When Is a Draft Accepted? A Theory of Acceptance in Speculative Decoding

This article develops a theory for speculative decoding regimes that use greedy decoding, relaxed acceptance rules, or tree-based candidate sets, rather than the stochastic distribution-preserving settings studied in existing literature. The authors characterize rejection regions as lower level sets of the target distribution to derive exact KL divergence requirements and sharp margin-based bounds for various acceptance criteria.

Improving Large-Scale Weakly Supervised ASR by Filtering and Selection

The authors propose a novel training approach for end-to-end automatic speech recognition (ASR) that addresses noisy labels and lack of domain specificity in large-scale weakly supervised datasets. The method involves pretraining on the full dataset, continued pretraining on a filtered subset based on character error rate, and fine-tuning on acoustically similar samples from that subset.

DriftGuard: Safety-Aware Multi-Monitor Detection and Selective Adaptation for Evolving Toxicity Moderation

This paper introduces DriftGuard, a framework that combines multi-monitor drift detection with selective model updating to address evolving toxicity in automated moderation systems. The system tracks specific safety-relevant shifts, such as identity-harm and toxic-risk drift, rather than relying solely on global distributional changes.

5ting at SemEval-2026 Task 8: Strong End-to-End Multi-Turn RAG via LLM-Based Reranking and Faithfulness Control

The authors introduce 5ting, a system designed for the SemEval-2026 Task 8 (MTRAGEval) which evaluates multi-turn Retrieval Augmented Generation (RAG) systems. The system addresses challenges such as context drift, under specification, and hallucination risk by combining dense retrieval with LLM-based reranking and faithfulness control.

Majority Vote Silences Minority Values: Annotator Disagreement at the Hate/Offensive Boundary in HateXplain

The study demonstrates that collapsing annotator disagreement into majority vote labels during hate speech annotation is not neutral, as 42.6% of all disagreement concentrates specifically at the hate/offensive boundary. This pattern indicates that annotators apply different thresholds for where hate begins, creating a structural issue in how ground truth is defined.

Structure-Preserving Document Translation via Multi-Stage LLM Pipeline: A Case Study in Marathi

This paper presents a framework for translating Marathi government documents to English that maintains layout fidelity and structural integrity, addressing limitations of existing systems that neglect formatting. The system integrates layout-aware OCR, coordinate-based text extraction, LLM translation, and HTML reconstruction to ensure spatial alignment and hierarchical consistency.

Categorizing Mathematical Concepts with LLM Voting Ensembles in Mathswitch

The open-source project Mathswitch imports mathematical concept records from sources like Wikidata and Wikipedia, linking records that refer to the same concept without reorganizing the original content. To address noise in the imported data, such as non-mathematical or ambiguous items, the authors test whether a voting ensemble of LLM judges can effectively filter this noise.

Labeling Training Data for Entity Matching Using Large Language Models

This paper investigates using large language models as teacher models in knowledge-distillation workflows to automatically label training data for smaller student models in entity matching tasks. The study evaluates various pair-selection strategies, teacher and student models, and post-processing methods across five standard benchmarks.

AgentSeal: A Corpus-Availability Audit of SWE-bench Pro

The AgentSeal v5 audit tool evaluated the public availability of artifacts in the SWE-bench Pro benchmark to assess potential contamination risks. The study found that while 12 instances showed deterministic content overlap and 76 repositories were probable corpus members, most evidence consisted of date-unknown public replication rather than proven pre-cutoff contamination.

The Heterogeneous Safety Impacts of Benign Multilingual Fine-Tuning

A comprehensive empirical study reveals that fine-tuning large language models with benign multilingual data significantly increases their tendency to comply with unsafe adversarial prompts, a phenomenon termed multilingual safety drift. The research demonstrates that safety outcomes are highly sensitive to both the language used for fine-tuning and the language of evaluation, with compliance rates increasing four-fold in certain settings.

License Compatibility Analysis of Corpora for Low-Resource African Languages

This paper audits the license provenance of over twenty corpus families used in African NLP, revealing that while Creative Commons licenses dominate releases, their compatibility rules are rarely applied. The authors construct a six-tier compatibility matrix and apply it to three case-study languages: Kituba/Munukutuba, Zarma, and Moore.

Memory-Managed Long-Context Attention: A Preliminary Study of Editable Request-Local Memory

This study investigates memory-managed long-context attention by separating a fast recurrent or sparse backbone from explicit editable request-local memory slots and query-time sparse fallback. The research aims to address the limitations of existing linear, recurrent, and sparse attention methods in managing when facts should be written, overwritten, protected, or discarded.

Latent Bridges for Multi-Table Question Answering

The authors introduce GRAB, a constructor-encoder-bridge pipeline designed for table question answering that lifts relational data into a heterogeneous graph and encodes it via message passing. The method transfers signals to a frozen large language model through a small set of query-conditioned latent tokens, providing a compact structural representation while preserving the LLM's general reasoning capabilities.
