💡 LLM Reasoning (82)¶
- Logical Phase Transitions: Understanding Collapse in LLM Logical Reasoning
-
This paper discovers the "logical phase transition" phenomenon in LLM logical reasoning—performance collapses abruptly at specific complexity thresholds rather than degrading smoothly. It proposes the Logical Complexity Measure (LoCM) to quantify this phenomenon and designs the Neuro-Symbolic Curriculum Tuning (NSCT) framework. Through adaptive neuro-symbolic alignment and complexity-aware curriculum optimization, NSCT improves accuracy by an average of +1.26 over naive prompting and +3.95 over CoT across five benchmarks.
- Semantic-Aware Logical Reasoning via a Semiotic Framework
-
Proposes LogicAgent, a logical reasoning framework based on the Greimas Semiotic Square, achieving SOTA logical reasoning performance under the dual challenges of semantic and logical complexity through multi-perspective semantic analysis and reflective verification.
- DRP: Distilled Reasoning Pruning with Skill-aware Step Decomposition for Efficient Large Reasoning Models
-
DRP allows a "Short-CoT teacher (GPT-4o)" to perform skill-level step decomposition and pruning/rewriting on the "Long-CoT student's (R1-Distill-Qwen)" own reasoning trajectories. By distilling these trajectories—which remove redundancy while preserving the student's speaking style—back into the student, DRP reduces the tokens of a 7B model on GSM8K from 917 to 328 (−64%) while increasing Pass@1 from 91.7% to 94.1%. It simultaneously reduces token counts and improves accuracy on OOD tasks like AIME/AMC/MATH500.
- TemplateRL: Structured Template-Guided Reinforcement Learning for LLM Reasoning
-
TemplateRL abstracts structured reasoning templates from a small seed set using MCTS and introduces these templates as explicit guidance during reinforcement learning training. This significantly improves the efficiency and stability of multi-step reasoning in LLMs, achieving a 99% improvement over GRPO on AIME.
- Is Chain-of-Thought Really Not Explainability? Chain-of-Thought Can Be Faithful without Hint Verbalization
-
This paper systematically refutes the popular recent conclusion that "CoT does not count as explainability." Using four complementary metrics—Filler Tokens, FUR, faithful@k, and Causal Mediation Analysis—it demonstrates that over half of CoT samples judged "unfaithful" by Biasing Features (hint verbalization) actually reflect model reasoning "in other ways." Unfaithfulness primarily stems from "incompleteness" due to lossy natural language compression rather than true divergence—increasing the sampling budget can raise hint verbalization probability to 90%, and even non-verbalized hints can causally transmit influence through the CoT.
- Render-of-Thought: Rendering Textual Chain-of-Thought as Images for Visual Latent Reasoning
-
Ours proposes Render-of-Thought (RoT), the first to render textual CoT reasoning steps into images. By utilizing a pre-trained visual encoder as a semantic anchor to align LLM hidden states with the visual embedding space, it achieves 3-4x token compression and significant inference acceleration while maintaining the analyzability of reasoning chains.
- LLM Reasoning as Trajectories: Step-Specific Representation Geometry and Correctness Signals
-
This paper models LLM chain-of-thought reasoning as geometric trajectories in the representation space. It discovers that (a) each reasoning step occupies a linearly separable subspace that becomes clearer in deeper layers, and (b) correct and incorrect solutions overlap in early stages but diverge systematically later. This allows predicting the final correctness with an ROC-AUC of 0.87 before the answer is output, leading to a proposed "trajectory steering" method for reasoning correction and length control.
- Revisiting Entropy in Reinforcement Learning for Large Reasoning Models
-
This work systematically investigates the entropy dynamics of LLMs during RLVR training, revealing that positive-advantage tokens are the primary drivers of entropy collapse. It introduces Positive-Advantage Reweighting to effectively regulate model entropy by dynamically adjusting the loss weights of these tokens.
- MTR-Bench: A Comprehensive Benchmark for Multi-Turn Reasoning Evaluation
-
MTR-Bench constructs an automated multi-turn reasoning evaluation framework comprising 4 categories, 40 tasks, and 3,600 instances, demonstrating that current frontier reasoning models remain unreliable in interactive and dynamic feedback environments.
- Parallel Test-Time Scaling for Latent Reasoning Models
-
This paper introduces parallel test-time scaling (parallel TTS) to latent reasoning models for the first time. It proposes two stochastic sampling strategies based on uncertainty theory (MC-Dropout and Additive Gaussian Noise) and a Latent Reward Model (LatentRM) trained with step-level contrastive learning. This enables models reasoning in continuous vector spaces to achieve stable performance gains through parallel sampling and aggregation.

- How Should We Enhance the Safety of Large Reasoning Models: An Empirical Study
-
This paper systematically investigates how to enhance the safety of Large Reasoning Models (LRMs) through SFT. It identifies that the root cause of the limited effectiveness of direct safety response distillation is five risk reasoning patterns (especially "weak vacillation"). The authors propose targeted distillation strategies that reduce the PAIR attack success rate from 63% to 13%, and find that short reasoning chains and template reasoning perform comparably to long reasoning chains in terms of safety.
- Robustness via Referencing: Defending against Prompt Injection Attacks by Referencing the Executed Instruction
-
This paper proposes a defense method against prompt injection based on instruction referencing. Instead of suppressing the instruction-following capability of LLMs, it requires the model to reference the instruction currently being executed within its response.

👻 Hallucination Detection (28)¶
- Hallucination Detection in LLMs with Topological Divergence on Attention Graphs
-
TOHA treats the LLM attention matrix as a weighted graph, utilizes Manifold Topology Divergence from topological data analysis (TDA) to measure the "topological novelty of the response subgraph relative to the prompt subgraph," and discovers "hallucination-aware heads" that are stable across datasets.

- The Reasoning Trap: How Enhancing LLM Reasoning Amplifies Tool Hallucination
-
This work systematically reveals the "Reasoning Trap" paradox: enhancing LLM reasoning capabilities (whether through RL, distillation, or switchable reasoning modes) systematically amplifies tool hallucinations. This effect is inherently associated with the reasoning process itself rather than RL training, and existing mitigation strategies (Prompt Engineering, DPO) face an inevitable reliability-capability trade-off.
- Through the Magnifying Glass: Adaptive Perception Magnification for Hallucination-Free VLM Decoding
-
This paper proposes Perception Magnifier (PM), a visual decoding method that iteratively identifies key visual regions using multi-layer attention during each autoregressive decoding step and adaptively magnifies them. By enhancing the effective resolution of key regions, it mitigates VLM visual hallucinations while maintaining spatial structural integrity and reasoning capabilities.
- Mechanisms of Prompt-Induced Hallucination in Vision–Language Models
-
In controlled object counting tasks, prompt-induced hallucination (PIH)—where the model follows the prompt rather than the image—is localized to 3–10 attention heads in the early layers (\(L0-1\)) of LLaVA-OneVision, Qwen-VL, and Janus-Pro. Mean ablation of these heads, requiring no retraining, reduces prompt-following from 42–64% to <11% and restores true counting rates to 70–78%, while zero-shot transferring to color identification (PIH suppression of 40–95%).
- FaithLens: Detecting and Explaining Faithfulness Hallucination
-
This paper proposes FaithLens, an 8B parameter faithfulness hallucination detection model. It undergoes cold-start SFT using high-quality data synthesis combined with three-dimensional filtering (label correctness, explanation quality, and data diversity), followed by further optimization via rule-based reinforcement learning (prediction correctness reward + explanation quality reward).

- FinGround: Detecting and Grounding Financial Hallucinations via Atomic Claim Verification
-
FinGround is a three-stage "verify-then-ground" pipeline for financial document QA: (1) finance-aware hybrid retrieval; (2) decomposing answers into atomic claims and verifying them using a type-routed strategy across a six-category taxonomy (Numerical, Temporal, Entity Property, Comparative, Regulatory, Computational—where computational claims use formula reconstruction and arithmetic re-verification); (3) grounded rewriting of unsupported claims with paragraph/cell-level citations. By distilling GPT-4o into an 8B detector, it achieves a 91.4% F1 score with 18× acceleration, reducing the hallucination rate by 78% compared to GPT-4o+CoT.
- Mitigating Hallucinations in Large Vision-Language Models without Performance Degradation
-
This paper proposes the MPD framework, which decouples hallucination components through semantic-aware orthogonal subspace projection and selectively updates a small number of parameters most relevant to hallucinations. While reducing hallucinations by 23.4%, it maintains 97.4% of general generation capability without introducing additional inference overhead.
- Two Pathways to Truthfulness: On the Intrinsic Encoding of LLM Hallucinations
-
This paper discovers that LLMs encode truthfulness signals through two distinct information pathways: Question-Anchored (dependent on information flow from question to answer) and Answer-Anchored (extracting self-contained evidence from the generated answer itself). These pathways are closely linked to knowledge boundaries. Based on this, the authors propose Mixture-of-Probes and Pathway Reweighting, achieving up to a 10% improvement in AUC for hallucination detection.

It comprises 172 composite workflows and 1,710 spreadsheets (27 million cells). Even the most advanced Agent, GPT 5.1 Pro, achieves only a 38.4% success rate despite an average execution time of 16.8 minutes, highlighting significant deficiencies of state-of-the-art AI Agents in real-world corporate scenarios.
- NovBench: Evaluating Large Language Models on Academic Paper Novelty Assessment
-
NovBench pairs "novelty claims in paper introductions" with "textual novelty evaluations from reviewers" to create a benchmark of 1,684 samples. Using four dimensions—Relevance, Correctness, Coverage, and Clarity—it systematically reveals that while current general-purpose and specialized LLMs can generate fluent evaluations, they still struggle to truly understand and comprehensively judge academic novelty.
- arXiv2Table: Toward Realistic Benchmarking and Evaluation for LLM-Based Literature-Review Table Generation
-
The authors present the arXiv2Table benchmark (1,957 tables, 7,158 papers), which achieves a more realistic evaluation of LLM-based literature-review table generation by introducing distractor papers, schema-agnostic user demands, and a QA-based reference-free evaluation framework, alongside an iterative batch generation method.
- BadScientist: Can a Research Agent Write Convincing but Unsound Papers that Fool LLM Reviewers?
-
The authors developed a "BadScientist" pipeline: a generation agent that conducts no real experiments uses five "performative fraud" strategies to write seemingly rigorous but fundamentally unsound papers. These are then fed to a multi-model reviewer agent composed of o3 / o4-mini / GPT-4.1. Results show that the acceptance rate for fraudulent papers reaches up to 82%. Furthermore, reviewers often point out integrity issues in their text comments while still assigning acceptance scores (concern-acceptance conflict), and existing mitigation methods perform barely better than random guessing.

CoMeT introduces a "global memory + FIFO temporary memory" dual-memory plug-in for existing LLMs. By processing inputs in chunks, it achieves constant memory and linear time complexity. Fine-tuned only on 32k context, it enables precise retrieval at any position within 1M tokens and proposes hierarchical pipeline parallelism to allow fine-tuning 128k context on 16×80GB GPUs.
- Task-Aware LLM Routing with Multi-Level Task-Profile-Guided Data Synthesis for Cold-Start Scenarios
-
A multi-level task-profile-guided data synthesis framework is proposed to address the cold-start problem in LLM routing. TRouter, a routing method using task types as latent variables, is designed to model the query-cost-performance relationship via variational inference, achieving effective routing in both cold-start and in-domain settings.
- The Illusion of Specialization: Revealing the "Standing Committee" in Mixture-of-Experts Models
-
By introducing the CommitteeAudit framework, the authors discover a "Standing Committee" in MoE models—a compact, persistent set of experts consistently activated and dominating routing weights across different domains. This contrasts with the widely assumed domain-specific specialization, revealing an inherent centralized structure in sparse computation.
- Alloc-MoE: Budget-Aware Expert Activation Allocation for Efficient Mixture-of-Experts Inference
-
The "number of activated experts" in MoE inference is abstracted as a global budget \(B\). Optimal Top-K allocation is performed across layers via dynamic programming (Alloc-L), followed by token-level redistribution using global Top-\((K \cdot T)\) selection (Alloc-T). This approach halves the activation budget of DeepSeek-V2-Lite while maintaining accuracy, achieving a 1.15× speedup in prefill and a 1.34× speedup in decode.
- Beyond Accuracy: Unveiling Inefficiency Patterns in Tool-Integrated Reasoning
-
This paper proposes PTE (Prefill Token Equivalents), a hardware-aware efficiency metric for tool-integrated reasoning (TIR) that unifies the costs of internal reasoning and external tool usage. Through large-scale experiments, it reveals four inefficiency patterns in TIR: confirmatory tool use, tool mixing, lack of tool priors, and tool format collapse.

- FOREVER: Forgetting Curve-Inspired Memory Replay for Language Model Continual Learning
-
The authors realign the "spaced repetition" concept of the Ebbinghaus forgetting curve from "training steps" to "model time" (accumulated parameter update norm \(\Delta_t = \|\Theta_t - \Theta_{t-1}\|_2\)). Specifically, cumulative model time \(\tau_t\) determines when to replay, while the instability ratio \(r_t\) (current update intensity \(\mu_t\) vs. baseline \(\mu_0\)) adaptively controls how to replay (regularization strength). The method consistently outperforms SOTA across 3 CL benchmarks and 4 backbones (0.6B–13B), achieving OP +1.2% and BWT +0.9% over the strongest baseline VBM.
- Data Mixing Agent: Learning to Re-weight Domains for Continual Pre-training
-
This paper proposes Data Mixing Agent, the first model-based end-to-end domain re-weighting framework. By training a small agent using CQL reinforcement learning on extensive data mixing trajectories, it learns generalizable data mixing heuristics. It balances performance between source and target domains in mathematical reasoning continual pre-training and generalizes to unseen source domains, target models, and domain spaces.
- Toward Consistent World Models with Multi-Token Prediction and Latent Semantic Enhancement
-
This paper theoretically analyzes how Multi-Token Prediction (MTP) induces representation contractivity through a gradient coupling mechanism, facilitating the emergence of belief states. However, it also reveals the "structural hallucination" problem of MTP (illegal shortcuts in latent space). The proposed LSE-MTP framework anchors predictions to true latent state trajectories through latent consistency and semantic anchoring losses, significantly improving path legality and robustness in synthetic graphs and real-world Manhattan taxi navigation.
- On the Proper Treatment of Units in Surprisal Theory
-
This paper points out that the choice of the "next unit" in surprisal theory has historically been implicitly determined by pre-trained language model tokenizers. It proposes a finite-state transduction framework that explicitly decouples model tokens, linguistic units, and experimental Regions of Interest (ROI), demonstrating on MECO eye-tracking data that different unit inventories fundamentally alter how surprisal predicts reading time.
- Compact Example-Based Explanations for Language Models
-
This paper proposes Selection Relevance Score, a re-training-free metric to evaluate the quality of training sample subsets as example-based explanations. It demonstrates that the common "select highest influence" strategy is often inferior to random selection and further introduces a new strategy that balances influence and representativeness.
- Fine-tuning vs. In-context Learning in Large Language Models: A Formal Language Learning Perspective
-
The authors utilize Probabilistic Hierarchical Context-Free Grammar (HPCFG) to construct a set of "contamination-free, bounded, and precisely samplable" formal languages as controlled testbeds. They propose the "Discriminative AUC Test" as a unified metric to systematically compare FT and ICL across 18 LLMs from 6 families on 6 languages. The study finds that FT consistently outperforms ICL in-distribution, but both perform equally on out-of-distribution data; ICL shares a similar inductive bias with FT but exhibits significantly higher sensitivity to specific tokens.
- Is a Document Educational or Just Wikipedia-Style? -- Pitfalls of Classifier-Based Quality Filtering
-
This paper discovers that Classifier-based Quality Filtering (CQF) mistakenly equates "Wikipedia-style writing" with "higher educational value." Simple rewriting allows low-quality web pages to bypass pre-training data filtering thresholds; approximately 7% of samples in FineWeb-Edu flip their filtering decisions as a result.
- KoCo: Conditioning Language Model Pre-training on Knowledge Coordinates
-
Ours proposes Knowledge Coordinate (KoCo) conditioning for pre-training, which maps each document to a three-dimensional semantic coordinate (Source, Content, Stability). These coordinates are injected into pre-training as text prefixes, providing the model with explicit context-awareness. This approach improves performance across 10 downstream tasks, accelerates convergence by approximately 30%, and effectively mitigates hallucinations.
- SAGE: Sign-Adaptive Gradient for Memory-Efficient LLM Optimization
-
Ours proposes the SAGE optimizer, which addresses the "embedding layer dilemma" where lightweight optimizers fail on embedding layers. By combining a Lion-style sign update direction with an \(O(d)\) memory overhead adaptive damping scaling factor, SAGE achieves new SOTA perplexity on Llama models (up to 1.3B) with significantly lower optimizer memory.
- Demystifying Data Organization for Enhanced LLM Training
-
This paper systematically investigates the impact of "sample appearance order" in LLM training. By reusing existing sample-level quality/difficulty scores, it proposes four data organization principles: boundary reinforcement, cyclic review, continuous curriculum, and local diversity. The proposed STR and SAW strategies consistently enhance performance in both pre-training and SFT.

✏️ Knowledge Editing (10)¶
- EvoEdit: Evolving Null-space Alignment for Robust and Efficient Knowledge Editing
-
Ours proposes EvoEdit, which achieves large-scale sequential knowledge editing by dynamically evolving a null-space projector. It efficiently injects new knowledge while maintaining existing knowledge, preserving SOTA performance at the 10K editing scale and running 3.5x faster than AlphaEdit.
- One Mask to Rule Them All: On Hidden Facts after Editing and How to Find Them
-
This paper discovers that ROME / MEMIT does not truly overwrite old knowledge but suppresses it through a shared overattention mechanism; a sparse binary mask can reverse most edits and reduce the success rate of new edits from 98% to 38%.
- Spectral Characterization and Mitigation of Sequential Knowledge Editing Collapse
-
The paper explains why sequential knowledge editing causes LLM general ability collapse from the perspective of SVD spectral structure and proposes REVIVE. By filtering update components that interfere with the dominant singular subspace within the singular vector basis of the original weights, REVIVE enables editors like MEMIT, RECT, and AlphaEdit to maintain both editing success rates and general capabilities under 10,000 to 20,000 continuous edits.
- FABLE: Fine-grained Fact Anchoring for Unstructured Model Editing
-
This paper identifies that existing unstructured model editing methods, while capable of holistic recall of edited text, fail to provide access to fine-grained facts. It proposes the FABLE framework, which uses a two-stage hierarchical strategy to anchor fine-grained facts in shallow layers and integrate holistic narratives in deep layers, and constructs the UnFine diagnostic benchmark for systematic evaluation.
- Aligning Language Models with Real-time Knowledge Editing
-
Introduces CRAFT (a continuously updated Chinese financial knowledge editing dataset) and KEDAS (a knowledge editing alignment paradigm based on diverse edit augmentation and adaptive inference) to resolve the difficulty of balancing success rate, locality, and portability in real-time knowledge editing scenarios.
- Can Factual Opinions Be Edited (Manipulated) in Large Language Models?
-
This paper points out that existing knowledge editing techniques can be used to manipulate the "documented stances of public figures" (factual opinions). To address this, the authors construct the FOE benchmark with evidence and find that current methods result in "surface-level opinion changes with contradictory evidence." They propose a two-stage Self-Generated Evidence-Aligned method, enabling edited models to provide self-consistent evidence for manipulated opinions without relying on explicit instructions.
- CLaRE-ty Amid Chaos: Quantifying Representational Entanglement to Predict Ripple Effects in LLM Editing
-
CLARE proposes a lightweight representational method that quantifies the degree of entanglement between facts through forward activations of a single intermediate layer. It is used to predict ripple effects in model editing, achieving an average improvement of 62.2% in Spearman correlation compared to gradient-based methods, while being 2.74x faster with 2.85x less memory consumption.
- HiEdit: Lifelong Model Editing with Hierarchical Reinforcement Learning
-
HiEdit utilizes hierarchical reinforcement learning to decompose "lifelong model editing" into two subtasks: high-level layer selection and low-level gradient update calculation. This allows the hypernetwork to adaptively modify only half of the layers based on specific knowledge, improving the strong baseline RLEdit by an average of 8.48%.
- Representation Interventions Enable Lifelong Knowledge Memory Control in LLMs
-
This paper proposes RILKE, which transforms lifelong knowledge editing from "modifying model weights" to "applying low-rank interventions in the hidden representation space." Through robust training, query-adaptive routing, and shared subspace modules, RILKE maintains near-perfect editing success rates and strong generalization after 1,000 unstructured knowledge edits while significantly reducing storage overhead.
- The Model Agreed, But Didn't Learn: Diagnosing Surface Compliance in Large Language Models
-
The SA-MCQ diagnostic framework is proposed to reveal the "surface compliance" phenomenon in knowledge editing—where editors achieve high scores on standard benchmarks but fail to truly overwrite internal beliefs. Models revert to original parametric memory in discriminative self-assessment, and sequential editing accumulates representational residue, leading to cognitive instability.
💬 LLM (Other) (62)¶
- A Study of LLMs' Preferences for Libraries and Programming Languages
-
This study presents the first systematic investigation into the preferences of 8 LLMs regarding libraries and programming languages during code generation. It reveals that LLMs exhibit a severe bias toward popular libraries like NumPy (45% unnecessary usage) and the Python language (chosen in 58% of high-performance tasks), and that natural language recommendations often diverge from actual code selection behavior.
- Confidence Estimation for LLMs in Multi-turn Interactions
-
This paper presents the first systematic study of LLM confidence estimation in multi-turn dialogue scenarios. It proposes two core desiderata (per-turn calibration and monotonicity with increasing information), the corresponding InfoECE metric and Kendall’s \(\tau\) evaluation, and the Hinter-Guesser dataset construction paradigm. A novel P(SUFFICIENT) logit probe is introduced. Findings indicate that existing methods (verbalized / SC / P(TRUE)) exhibit poor calibration and monotonicity in multi-turn settings. In contrast, P(SUFFICIENT) reduces InfoECE to 5.27 on the GUESS task (vs. 79.97 for P(TRUE)) and achieves a \(\tau\) of 81.51, although the task remains far from solved.
- When TableQA Meets Noise: A Dual Denoising Framework for Complex Questions and Large Tables
-
By decomposing semantic units in questions and constructing evidence trees for transparent table pruning, the EnoTab framework achieves significant performance gains when processing complex questions and ultra-large tables, effectively mitigating the negative impact of noisy data on reasoning through a dual denoising mechanism.
- One Persona, Many Cues, Different Results: How Sociodemographic Cues Impact LLM Personalization
-
This paper systematically compares the effects of 6 common persona prompting methods (two variants each for name, explicit mention, and dialogue history) across 7 LLMs and 4 tasks. The study find that while average responses are highly correlated across prompting methods, the differences between personas generated by different methods vary significantly. Overly explicit prompts lead to stronger personalization bias, suggesting that bias conclusions should not be drawn based on a single prompting method.
- Generative Interfaces for Language Models
-
This paper proposes Generative Interfaces (GenUI), which enables LLMs to move beyond single-box chat responses by generating interactive Web interfaces tailored to specific queries. Using a structured intermediate representation of "interaction flow graphs + finite state machines" and "adaptive reward-driven iterative refinement," GenUI achieves an 84% overall preference win rate against Claude 3.7's chat UI across 100 UIX prompts.
- MulDimIF: A Multi-Dimensional Constraint Framework for Evaluating and Improving Instruction Following in Large Language Models
-
The authors propose MulDimIF, a multi-dimensional constraint framework that systematically evaluates the instruction-following capabilities of LLMs across three dimensions: constraint patterns (3 types), constraint categories (4 categories, 13 subcategories), and constraint difficulty (4 levels). Model performance is significantly improved via GRPO training, with findings indicating that improvements primarily stem from parameter updates in the attention modules.
- Can AI Be a Good Peer Reviewer? A Survey of Peer Review Process, Evaluation, and the Future
-
The authors provide a systematic survey of AI-assisted peer review methods in the LLM era. They categorize "review generation" into four paradigms: fine-tuning / agent / RL / generation enhancement, classify "after-review" into rebuttal / meta-review / paper revision, and present a four-quadrant evaluation taxonomy (human / reference-based / LLM-based / aspect-oriented). Finally, they discuss the future across six directions: novelty, automatic evaluation, cross-domain, multimodality, and ethics.
- Automatic Combination of Sample Selection Strategies for Few-Shot Learning
-
This paper proposes the ACSESS method, which automatically identifies and combines complementary sample selection strategies through three mechanisms: forward selection, backward selection, and Datamodels. Validated across 23 strategies, 5 ICL models, 3 gradient-based few-shot learning methods, and 14 datasets (6 text, 8 image), the combined strategy consistently outperforms single strategies and ICL-specific baselines.
- Min-k Sampling: Decoupling Truncation from Temperature Scaling via Relative Logit Dynamics

- Agree, Disagree, Explain: Decomposing Human Label Variation in NLI through the Lens of Explanations
-
The LiTEx reasoning taxonomy is extended from "explanation variation under label agreement" to "label disagreement" scenarios. It is found that annotators may have different labels but similar reasoning, and the consistency of reasoning categories reflects the semantic similarity of explanations better than label consistency.
- Beyond Chunking: Discourse-Aware Hierarchical Retrieval for Long Document Question Answering
-
This paper leverages Rhetorical Structure Theory (RST) to parse the discourse organization of long documents, constructing a sentence-level hierarchical tree with intermediate nodes enhanced by LLM summarization. By performing structure-aware multi-granularity retrieval on this tree, the proposed method consistently outperforms fixed-size chunking and RAPTOR-style semantic clustering across four benchmarks: QASPER, QuALITY, NarrativeQA, and MultiFieldQA-zh.
- MTSQL-R1: Towards Long-Horizon Multi-Turn Text-to-SQL via Agentic Training
-
MTSQL-R1 transforms multi-turn Text-to-SQL from "one-shot translation" into a long-horizon agent training problem that interacts with databases and dialogue memory. Through self-teaching warm-start SFT and multi-level GRPO rewards, small-scale Qwen3 models outperform strong closed-source prompting baselines and short-horizon SFT/RL baselines on CoSQL and SParC.
- Table Question Answering in the Era of Large Language Models: A Comprehensive Survey
-
This paper provides a comprehensive survey of Table Question Answering (TQA) research in the LLM era. It systematically categorizes task settings across five dimensions (table format, question complexity, answer format, modality, and domain) and organizes modeling approaches based on core challenges (table understanding, complex queries, large inputs, data heterogeneity, and knowledge integration). Covering 277 papers, it also provides forward-looking discussions on emerging directions such as reinforcement learning and interpretability.
- Test-Time Reasoners Are Strategic Multiple-Choice Test-Takers
-
This paper systematically compares 12 reasoning LLMs on full multiple-choice questions (MCQs) versus choices-only MCQs. It finds that test-time reasoning (TTR) indeed allows models to perform above chance in choices-only scenarios. However, reasoning traces reveal that this is not entirely shallow cheating but includes "strategic test-taking" behaviors such as inferring missing questions, eliminating incorrect options, and invoking factual knowledge.
- ASTRA: Adaptive Semantic Tree Reasoning Architecture for Complex Table Question Answering
-
ASTRA adaptively reconstructs complex tables into semantic trees and employs a dual-mode reasoning approach consisting of text tree navigation and symbolic code execution. It achieves accuracies of 91.6%, 81.9%, and 90.1% on AIT-QA, SSTQA, and HiTab, respectively, outperforming strong LLMs and existing table structuralization methods.
- Can LLMs Estimate Cognitive Complexity of Reading Comprehension Items?
-
This paper constructs the ReCo reading comprehension cognitive complexity dataset and systematically evaluates whether 8 LLMs can automatically determine the required evidence scope and transformation levels for items. Results indicate that strong models approach but remain significantly lower than experts, particularly in identifying complete evidence sets and fine-grained word-order transformations.
- Lost in the Prompt Order: Revealing the Limitations of Causal Attention in Language Models
-
This paper investigates the sensitivity of Large Language Models (LLMs) to the order of prompt components in multiple-choice questions (MCQA). Through systematic experiments, it excludes training bias and memory decay hypotheses, revealing that the causal attention mask is the fundamental mechanism leading to significant performance degradation in the QOC (Question-Options-Context) order.

- Frankentext: Stitching Random Text Fragments into Long-Form Narratives
-
This paper proposes the Frankentext paradigm, which enables LLMs to stitch random human text fragments into coherent long-form narratives under extreme constraints (90% of text copied verbatim from human writing). This reveals the severe failure of current AI text detectors in mixed-authorship scenarios (72% of Frankentext is misclassified as human writing).
- ConlangCrafter: Constructing Languages with a Multi-Hop LLM Pipeline
-
This paper introduces ConlangCrafter, an LLM-based multi-hop pipeline that decomposes constructed language (conlang) design into modular stages of phonology, grammar, and lexicon.

- XtraGPT: Context-Aware and Controllable Academic Paper Revision via Human-AI Collaboration
-
This paper presents XtraGPT—the first open-source LLM suite (1.5B–14B) specifically for academic paper revision. By fine-tuning on 7,000 top-tier conference papers and 140,000 standard-guided instruction-revision pairs, it achieves context-aware paragraph-level controllable revisions. The 7B version matches GPT-4o-mini, while the 14B version outperforms GPT-4o-mini. Human evaluations show an average increase of 0.65 points in predicted paper scores after revisions.
- In-depth Research Impact Summarization through Fine-Grained Temporal Citation Analysis
-
This paper proposes the "Scientific Impact Summarization" task: first identifying fine-grained intents that truly reveal impact from the citation contexts of a paper, and then generating an impact narrative that evolves over time. This approach better illustrates how a paper is adopted, criticized, and transformed by subsequent work compared to simple citation counts.
- Adaptive Planning for Multi-Attribute Controllable Summarization with Monte Carlo Tree Search
-
This paper proposes PACO, which reformulates "multi-attribute controllable summarization" as a planning problem to find an "attribute control sequence." Using a customized Monte Carlo Tree Search (where nodes are full summaries and actions are single-attribute adjustments), it identifies the optimal adjustment path during the prompting stage without any attribute-specific training. With Llama-3.2-1B, it achieves controllability comparable to the Llama-3.3-70B baseline, while Llama-3.3-70B + PACO surpasses all existing methods.
- Can You Make It Sound Like You? Post-Editing LLM-Generated Text for Personal Style
-
The authors conducted a pre-registered online study with 81 participants who used GPT-o4-mini to draft and then manually post-edit style-sensitive texts such as wedding vows and apology letters. The findings reveal that while post-editing significantly moves the text toward the user's personal style and away from the LLM's style, the edited texts still systematically retain more "AI-like" traces than independent writing—a residue that participants themselves fail to perceive.
- Children's English Reading Story Generation via Supervised Fine-Tuning of Compact LLMs with Controllable Difficulty and Safety
-
The authors utilized 2,580 stories generated by GPT-4o / Llama-3.3-70B corresponding to the UFLI K–2 English reading curriculum to perform four SFT designs (baseline, Good Stories, Rewarded SFT, and simulated children's pronunciation errors) on three 8B models (Llama 3 / Granite 3.3 / Apertus). The results demonstrate that compact models + appropriate SFT strategies can outperform zero-shot GPT-4o and Llama-3.3-70B on key K-2 metrics such as Spache readability, syntactic complexity, and toxicity. Among these, Rewarded SFT proved most stable and nearly hallucination-free.
- EDUMATH: Generating Standards-aligned Educational Math Word Problems
-
The authors systematize the task of "generating math word problems (MWP) aligned with K-12 math curriculum standards," collecting 11,000+ STEM MWP training data points annotated by real US teachers. Through an SFT + KTO + ModernBERT filtering pipeline, they trained two open-source SOTA generators, EDUMATH-12B/30B. They conducted the first RCT on actual 3rd-5th grade students, finding that while student accuracy was comparable between LLM-generated and human-written problems, students showed an almost unanimous preference for customized LLM problems.
- FACTS: Table Summarization via Offline Template Generation with Agentic Workflows
-
Ours proposes FACTS (Fast, Accurate, and Privacy-Compliant Table Summarization), which automatically generates reusable offline templates (SQL queries + Jinja2 templates) through a three-stage Agentic workflow. It achieves rapid, accurate, and privacy-compliant query-focused table summarization, outperforming baselines across FeTaQA, QTSumm, and QFMTS benchmarks.
- Investigating the Representation of Backchannels and Fillers in Fine-tuned Language Models
-
This paper trains BERT, GPT-2, TurnGPT, LLaMA-3 8B, and Qwen-3 8B on English and Japanese spoken dialogue corpora using three fine-tuning tasks: MASK, NTP, and TTP. It utilizes t-SNE visualization and silhouette clustering to quantify the representation quality of "backchannels" (e.g., uh-huh) and "fillers" (e.g., um). The study finds that fine-tuning significantly distinguishes these "semantically bleached" functional words within the embedding space and enables models to naturally generate diverse backchannels/fillers during NLG, marking a quantifiable step toward "human-like conversational LMs."

🗣️ Dialogue Systems (26)¶
- Simulated Students in Tutoring Dialogues: Substance or Illusion?
-

- Context-Agent: Dynamic Discourse Trees for Non-Linear Dialogue
-
The authors propose Context-Agent, which models multi-turn dialogue history as a "forest of discourse trees" (where each tree represents an independent topic and each branch represent an instruction refinement/fork). Nodes are organized by navigational intent rather than semantic similarity. Accompanying the model is the NTM benchmark for evaluating non-linear long-range dialogues, demonstrating improved task completion rates and reduced token consumption across various LLMs.
- Author-in-the-Loop Response Generation and Evaluation: Integrating Author Expertise and Intent in Responses to Peer Review

- Metro: Towards Strategy Induction from Expert Dialogue Transcripts for Non-collaborative Dialogues
-
Metro automatically induces expert dialogue transcripts into a "Strategy Forest"—a collection of trees rooted in K-Means clustered dialogue states. Each node represents an LLM-expanded micro-principle action, and branches represent complete action trajectories pruned by Wilson confidence lower bounds and MCTS-style value backpropagation. During inference, it retrieves a specific tree to extract short-term (breadth) and long-term (depth) recommendations in parallel. Without any training, it outperforms baselines such as PRINCIPLES, PPDPP, and GDP-Zero by approximately 10% on P4G and CB non-collaborative dialogue tasks.
- Reasoning Gets Harder for LLMs Inside A Dialogue
-
This paper introduces the Boulder dynamic benchmark, demonstrating that while LLMs perform well on isolated reasoning problems, their performance significantly degrades when the same problems are embedded in task-oriented dialogues. This is primarily attributed to multi-turn context, dialogue role constraints, and the burden of tool calling.
- STRIDE-ED: A Strategy-Grounded Stepwise Reasoning Framework for Empathetic Dialogue Systems
-
This paper proposes the STRIDE-ED framework, which constructs a comprehensive empathetic strategy system covering positive/neutral/negative emotions. By designing task-aligned multi-stage cognitive CoT reasoning combined with strategy-aware data refinement and a two-stage SFT+PPO training paradigm, it achieves SOTA performance in empathetic dialogue across multiple open-source LLMs, reaching an emotion accuracy of 57.25% and a BLEU-4 of 4.67.

🌐 Multilingual & Translation (64)¶
- Evaluating Robustness of Large Language Models Against Multilingual Typographical Errors
-
This paper proposes MulTypo—a multilingual typo generation algorithm based on language-specific keyboard layouts and 10-finger typing habits. It systematically evaluates the robustness of 18 open-source LLMs across 12 languages and 5 downstream tasks, demonstrating that typos significantly impact generation and reasoning tasks, instruction-tuned models are more fragile, and typo effects exhibit cross-lingual and directional asymmetry.
- Beyond Literal Mapping: Benchmarking and Improving Non-Literal Evaluation Evaluation
-
The authors construct MENT, a meta-evaluation dataset for non-literal translation (7,530 human annotations), revealing the unreliability of traditional metrics and LLM-as-Judge in non-literal scenarios. They propose the RATE agentic evaluation framework, which improves correlation with human judgment by over 3.2 points through a reflective core agent that dynamically invokes functional sub-agents.
- LaoBench: A Large-Scale Multidimensional Lao Benchmark for Large Language Models
-
LaoBench is the first large-scale, multidimensional Lao evaluation benchmark for LLMs, containing 17,000+ expert-curated samples. It covers three dimensions: Culture-Knowledge Application, Lao K12 Curriculum, and Lao-Chinese-English trilingual translation. It features a unique three-part design—Open-source 7k + Black-box 10k + Open-ended 500. The 10k black-box set prevents contamination via a controlled scoring service. Mainstream closed-source models (GPT-5-High, Gemini-2.5-Pro, etc.) still lag behind human experts by ~10-20 percentage points, indicating that Lao cultural reasoning and translation fidelity remain significant unsolved challenges.
- Evaluating the Impact of Verbal Multiword Expressions on Machine Translation
-
This paper presents the first systematic evaluation of the impact of Verbal Multiword Expressions (VMWEs: Verbal Idioms (VID), Verb-Particle Constructions (VPC), and Light Verb Constructions (LVC)) on machine translation quality. Analyzing 8 MT systems across 7 language pairs using two QE models and human DA scores, the study proves that VMWEs consistently lead to performance degradation. This degradation is strictly positively correlated with "non-compositionality" (VID > VPC > LVC), and even GPT-4.1/GPT-5.1 cannot eliminate this regression.
- Is Human-Like Text Liked by Humans? Multilingual Human Detection and Preference Against AI
-
The authors organized 19 native experts to conduct 8.8k human-machine text discrimination trials across 16 datasets involving 9 languages, 9 domains, and 11 SOTA LLMs. They found that the average expert accuracy reached 87.6% (significantly higher than the "near random" conclusions of early studies) and further revealed that while machine text rewritten with prompts explicitly addressing differences can lower detection accuracy to 72.5%, humans tend to prefer machine text when they cannot distinguish its source, challenging the implicit assumption that "human-like equals liked-by-human."
- TransLaw: A Large-Scale Dataset and Multi-Agent Benchmark Simulating Professional Translation of Hong Kong Case Law
-
This paper constructs the first sentence-level parallel dataset, HKCFA Judgement 97-22, specifically for English-Chinese translation of Hong Kong Court of Final Appeal judgements.

- GoViG: Goal-Conditioned Visual Navigation Instruction Generation via Multimodal Reasoning
-
GoViG proposes a new task of generating navigation instructions based only on initial and goal egocentric observations. It decomposes the task into two steps: "imagining intermediate frames then writing instructions." By jointly training Anole-7B with a dual objective of token-level MSE and label-smoothing CE, and employing one-pass or interleaved multimodal reasoning strategies, the method improves the BLEU-4 score from a baseline of 0.08 to 0.32, maintaining 0.27 on cross-domain real-world videos.

-
SkillNav decomposes the vision-language navigation task into 5 atomic skills (Direction Adjustment, Vertical Movement, Stop, Landmark Identification, Area Identification) + 1 Temporal Order Planning skill. Each skill fine-tunes a DUET sub-agent using synthetic data, while a training-free VLM router performs temporal reordering + sub-goal localization + skill selection. It achieves SOTA generalization capabilities on GSA-R2R (Test-N-Scene SPL 48% vs. the previous highest of 43%).
- Libra-VLA: Achieving Learning Equilibrium via Asynchronous Coarse-to-Fine Dual-System
-
Libra-VLA decomposes robot actions into a hybrid action space of "discrete macro-intent + continuous micro-pose." It utilizes System 2 (VLM + parallel coarse-action head) for low-frequency planning and System 1 (diffusion transformer + independent SigLIP encoder) for high-frequency refinement. Achieving true asynchronous execution via an intent buffer, it reaches a SoTA of 97.2% on LIBERO and 79.5% zero-shot on LIBERO-Plus (10% higher than the previous OpenVLA-OFT+).
- Limited Linguistic Diversity in Embodied AI Datasets
-
This paper performs a systematic "linguistic diversity audit" on mainstream VLA training corpora (RT-1, BRIDGE, TacoPlay, Language Table, LIBERO). By quantifying lexical, semantic, and syntactic dimensions, it reveals that VLA data contains < 2% unique instructions, RT-1 has only 49 unique words in the entire corpus, and negation/conditional sentences account for < 1%. This "template-based poverty" compared to instruction-tuning corpora (OASST2 93%, Alpaca 99.8% unique) may be the root cause of VLA models' vulnerability to paraphrasing and generalization failures.

To address two major reliability bottlenecks in RL for Diffusion Language Models (dLLM)—sparse rewards and probability estimation bias—the authors propose d-TreeRPO. It organizes rollouts into a tree structure, calculating step-wise advantages bottom-up using verifiable rewards from leaf nodes. Simultaneously, it provides a theoretical proof that "higher model confidence leads to more accurate single-step forward probability estimation," and designs a time-scheduled self-distillation loss to sharpen the policy in later training stages. Tested on LLaDA-8B-Instruct, it achieves gains of +86.2% on Sudoku, +51.6% on Countdown, +4.5% on GSM8K, and +5.3% on Math500.

-
KnowRL integrates "atomic fact verification" as a process-level reward directly into the GRPO training loop, performing factual assessment on each step of the slow-thinking model's Chain-of-Thought (CoT). Simultaneously, it employs a "positive reward for refusal" strategy to teach the model to identify its own knowledge boundaries.

The authors propose using an on-policy incentivised test set to predict generalization failures in real-world monitoring.
- Linear Probes Detect Task Format, Not Reasoning Mode in Language Model Hidden States
-
This paper uses probes, residual de-confounding, trace-anchor, and causal steering experiments on Qwen3-14B to demonstrate that while linear probes appear to distinguish deductive, inductive, and abductive reasoning with 100% accuracy, they actually detect data source and task format rather than reasoning modes within hidden states.

Evaluation of 15 LME's shows Gemini-2.5-Pro achieving the highest average \(\text{CEM}=63.07\) but still lacking ~15% of the knowledge; further tests using knowledge editing methods like FT-LLM / IKE effectively update outdated knowledge in LLaVA-v1.5 and Qwen-VL under single editing, but performance significantly degrades under lifelong editing (FT-LLM drops by 43.2% on average).
- Probing Semantic Alignment, Lexical Invariance, and Syntactic Influence in LLM Metaphor Processing
-
This is a diagnostic analysis paper: instead of competing for performance, the authors probe LLM metaphor processing from three complementary dimensions—semantic property alignment, lexical invariance, and syntactic influence. They find that "high scores on metaphor benchmarks" may stem from heterogeneous shallow signals (semantic drift + stable lexical anchors + heuristic sensitivity to syntactic irregularities) rather than robust integrated semantic understanding.

- The Pitfalls of KV Cache Compression
-
This paper identifies that KV cache compression leads to selective forgetting and system prompt leakage in multi-instruction prompts.

The authors propose two simple modifications—whitelist retention and fair eviction—to significantly reduce leakage and stabilize instruction following.
- LLM Prompt Duel Optimizer: Efficient Label-Free Prompt Optimization
-
This paper formalizes label-free prompt optimization as a dueling bandit problem and proposes the Prompt Duel Optimizer (PDO).
