A new benchmark, Atrex-Bench, drawn from full-cluster production inference traces shows that even the best frontier coding agents reach only ~10% of hardware roofline on real GPU operators, with correctness inflated by P…

Researchers have discovered that Diffusion Multimodal Large Language Models (DMLLMs) reveal their valid semantic boundary at the first denoising step through a shift in MLP activation sparsity, enabling a training-free f…

Researchers propose CoEvoT, a co-evolving chain-of-thought prompting framework that improves graph-LLM reasoning under distribution shift by iteratively updating graph tokens based on intermediate textual thoughts. Exper…

A new study from researchers at an undisclosed institution developed a digital-twin-inspired time-to-event model that integrates longitudinal ALSFRS-R trajectories with survival modeling to predict functional decline and…

A new survey from arXiv proposes a mathematical taxonomy for local additive feature attribution methods in explainable AI, organizing Shapley, path-based, gradient/backpropagation, perturbation, and CAM-style methods aro…

Researchers at a single pediatric institution developed TEDDY (Temporal Event Decoder for Disease in Youth), a 1.84-million-parameter decoder transformer trained on approximately 73 million ICD-10 diagnoses from 1.6 mill…

A 135M-class depth-recurrent transformer trained on FineWeb-Edu converges to a per-token fixed point, with mean successive-output KL divergence falling from 3.9e-1 at the second loop to 8.5e-6 by the sixteenth. The resea…

A new three-level hierarchical learning architecture for autonomous UAV swarms in search and rescue integrates Hebbian neuroplasticity, multi-agent reinforcement learning with graph neural networks and behavior trees, an…

A new arXiv preprint proposes the Capability Convergence Hypothesis (CCH), which states that under a fixed per-token inference budget, representational convergence does not entail capability convergence; instead, capabil…

Researchers introduced RegNetAgents, a multi-agent AI framework for identifying regulatory driver candidates across heterogeneous gene regulatory networks in cancer genomics. The system integrates TCGA-derived cancer net…

Researchers introduce Ego Scene Augmentation (ESA), an egocentric spatial perception framework that enhances spatial reasoning in Multimodal Large Language Models (MLLMs) for egocentric Visual Question Answering (VQA). T…
