• KernelBench-X: A Comprehensive Benchmark for Evaluating LLM-Generated GPU Kernels \ LLM-based Triton kernel generation has attracted significant interest, yet a fundamental empirical question remains unanswered: where does this capability break down, and why? We present KernelBench-X, a benchmark designed to answer this q… \ Source • arXiv cs.LG • 16:18
• Benchmarking POS Tagging for the Tajik Language: A Comparative Study of Neural Architectures on the TajPersParallel Corpus \ This paper presents the first benchmark for the task of automatic part-of-speech (POS) tagging for the Tajik language. Despite the existence of multilingual language models demonstrating high effectiveness for many of the world's languages… \ Source • arXiv cs.CL • 09:26
• When LLMs get significantly worse: A statistical approach to detect model degradations \ Minimizing the inference cost and latency of foundation models has become a crucial area of research. Optimization approaches include theoretically lossless methods and others without accuracy guarantees like quantization. In all of these … \ Source • arXiv cs.LG • 19:38
• Low-Cost Black-Box Detection of LLM Hallucinations via Dynamical System Prediction \ Large Language Models (LLMs) frequently generate plausible but non-factual content, a phenomenon known as hallucination. While existing detection methods typically rely on computationally expensive sampling-based consistency checks or exte… \ Source • arXiv cs.LG • 19:07
• ContextPilot: Fast Long-Context Inference via Context Reuse \ AI applications increasingly depend on long-context inference, where LLMs consume substantial context to support stronger reasoning. Common examples include retrieval-augmented generation, agent memory layers, and multi-agent orchestration… \ Source • arXiv cs.LG • 17:59
• Text Corpora as Concept Fields: Black-Box Hallucination and Novelty Measurement \ We introduce the **Concept Field** of a text corpus: a local drift field with pointwise uncertainty, estimated in sentence-embedding space from the deltas between consecutive sentences. Given a candidate sentence transition, we score its a… \ Source • arXiv cs.CL • 18:38
• TabEmbed: Benchmarking and Learning Generalist Embeddings for Tabular Understanding \ Foundation models have established unified representations for natural language processing, yet this paradigm remains largely unexplored for tabular data. Existing methods face fundamental limitations: LLM-based approaches lack retrieval-c… \ Source • arXiv cs.CL • 16:22
• OceanPile: A Large-Scale Multimodal Ocean Corpus for Foundation Models \ The vast and underexplored ocean plays a critical role in regulating global climate and supporting marine biodiversity, yet artificial intelligence has so far delivered limited impact in this domain due to a fundamental data bottleneck. Sp… \ Source • arXiv cs.CL • 14:52
• ReasoningGuard: Safeguarding Large Reasoning Models with Inference-time Safety Aha Moments \ Large Reasoning Models (LRMs) have demonstrated impressive performance in reasoning-intensive tasks, but they remain vulnerable to harmful content generation, particularly in the mid-to-late steps of their reasoning processes. Current defe… \ Source • arXiv cs.CL • 08:58
• RLearner-LLM: Balancing Logical Grounding and Fluency in Large Language Models via Hybrid Direct Preference Optimization \ Direct Preference Optimization (DPO), the efficient alternative to PPO-based RLHF, falls short on knowledge-intensive generation: standard preference signals from human annotators or LLM judges exhibit a systematic verbosity bias that rewa… \ Source • arXiv cs.CL • 08:36
• Sharp Capacity Thresholds in Linear Associative Memory: From Winner-Take-All to Listwise Retrieval \ How many key-value associations can a $d\times d$ linear memory store? We show that the answer depends not only on the $d^2$ degrees of freedom in the memory matrix, but also on the retrieval criterion. In an isotropic Gaussian model for t… \ Source • arXiv cs.LG • 19:53
• Superposition Is Not Necessary: A Mechanistic Interpretability Analysis of Transformer Representations for Time Series Forecasting \ Transformer architectures have been widely adopted for time series forecasting, yet whether the representational mechanisms that make them powerful in NLP actually engage on time series data remains unexplored.
