A new arXiv paper (2609.13194v1) reports that exact polynomial invariants, canonicalised as reduced Gröbner bases over Q, are more useful for diagnosing faults in reinforcement learning simulators and world models than f…
Researchers introduced SPICE (Simple Polysemantic Feature Interpretation via Clustering-based Explanation), a framework for analyzing polysemanticity in deep vision architectures, detailed in arXiv paper 2609.13198v1. SP…
A new arXiv paper (2609.13201v1) models AI-generated text and images as anomalies linked to main data points and derives bounds on the minimum size of a strongly dissimilar decomposition of random datasets using redundan…
A controlled study across several versions of two major tabular foundation model (TFM) families found that feature engineering gains are concentrated in earlier model generations and become negligible for the strongest m…
Researchers introduced embedding-based partial information decomposition (ePID), a scalable pipeline that compresses nonfocal symptoms into a low-cardinality discrete embedding to compute a tractable two-source PID, acco…
A new arXiv paper, arXiv:2609.13204v1, introduces GradRepair-ODE, a reliability framework that checks, repairs, and rejects gradients in neural ODE training at the optimizer step. Across six synthetic ODE systems, GradRe…
Researchers introduced ReCAST (Reward Credit ASsignment across Timesteps), a method for per-reward, timestep-dependent credit assignment in diffusion reward fine-tuning, detailed in arXiv paper 2609.13425v1. ReCAST uses …
Researchers introduced MACCHIATO, a specialized training algorithm that jointly constructs an explicitly structured ReLU-MLP from partial truth-table observations and an explicit Boolean circuit over signed literals with…
A new analysis method called Elo-per-token measures how large language model agents allocate test-time compute as they revise solutions, use tools, explore alternatives, and decide when to stop, addressing the difficulty…
A training-free, CPU-only lexical prompt-compression pipeline reduced prompt tokens by a mean of 40.3% (sigma = 9.2) while holding BERTScore-F1 at 0.876 against original-prompt output, according to an arXiv paper (2609.1…
Token merging speeds up multilingual speech recognition in the Whisper model family with almost no loss in transcription accuracy across sixteen languages and three model sizes, according to an arXiv paper (arXiv:2609.13…
Researchers introduced TestHallVQA, a multi-image visual question answering benchmark built from scientific exams that combines document-level scale with human-examination difficulty, according to the arXiv paper 2609.13…
A new arXiv paper, RFCLLM, evaluates how well large language models reason about network protocol state machines, testing 16 protocols across 4 tasks and 1482 task queries. The study compares each LLM's implicit finite-s…
A maxillofacial cone beam CT report generation system scored 0.4122 against a composite objective that weights 80% on large language model factual entailment and 20% on lexical overlap, versus 0.2909 for a report selecte…
A new arXiv paper (2609.13454v1) introduces a paired benchmark of 171 PubMed Central Open Access case reports — 40 sepsis and 131 GLP-1/diabetes cases — to measure hindsight bias in clinical temporal reasoning by large l…
A new arXiv paper (2609.13481v1) presents a Hybrid Hierarchical CNN-LSTM Summarizer that frames biomedical and clinical summarization as extractive sentence selection rather than generation, eliminating hallucination ris…
Researchers identified Harmfulness Propagation Dynamics (HPD), a cross-layer signature in which the projection of the last-token hidden state onto a learned harm direction rises monotonically with transformer depth for h…
Researchers proposed ModelLog, a declarative probabilistic framework for pre-training evaluation of large language models that specifies evaluation targets as symbolic constraints over token-level predictions, according …
Researchers built pseudo-references for the WMT26 General MT task's 10 reference-free language pairs by translating 3,277 official documents with seven models across up to five prompt conditions, producing 26 system-prom…
A new arXiv paper (2609.13581v1) presents an evidence-driven alignment framework for hospital discharge summarization that treats provenance as a first-class constraint, using semantic graphs and deep learning models to …
