Researchers have developed a methodology for the inverse design of critical experiments using deep neural network surrogate modeling and gradient optimization to maximize neutronic similarity to target nuclear technologi…

Researchers have developed UniCanvas, a diffusion-based unified model that generates interleaved text and images within a single pixel canvas. The model embeds language as visual patterns during image synthesis, overcomi…

Researchers have developed SBP-Net, a new method for reconstructing thin 3D structures such as blood vessels and industrial pipes that are often missed by existing neural techniques. The approach uses a sliding box to ge…

Multimodal large language models fail to infer how individual mental states interact and crystallize into group-level outcomes, according to a new benchmark called GroupToM-Bench. The benchmark, the first for group-level…

Researchers have developed a diffusion model that separates reflections from a single image by simultaneously generating transmission and reflection layers through a unified framework. The model introduces a cross-layer …

A large-scale study of biomedical question-answering systems found that retrieval-augmented generation (RAG) provides only small and inconsistent accuracy improvements—typically 1-2 percentage points—over models that do …

Researchers introduced a methodology using CausalBERT, enhanced with temperature scaling, hyperparameter optimization, and interpretability methods, to isolate the impact of specific factors on online review ratings. The…

Researchers have developed LazyAttention, a new attention mechanism that enables zero-copy, position-agnostic key-value cache reuse for large language models by deferring positional encoding to within attention kernels. …

Researchers have developed RUBAS, a rubric-based reinforcement learning framework designed to improve safety in large language model (LLM) agents that execute real-world tasks. The framework evaluates agent behavior acro…

Researchers have identified a structural collapse in the Boolean Task Algebra (BTA) framework for reinforcement learning, showing that in deterministic environments, all optimal extended Q-value functions are determined …

Researchers have developed a differentiable Neural Architecture Search (NAS) framework that jointly optimizes both architectural configurations and mixed-precision quantization for compressing large language models (LLMs…

Researchers have developed a principle-driven foundation model that encodes signal-theoretic principles like Fourier decomposition and energy conservation, achieving cross-modal transfer from radio-frequency data to audi…

A new paper situates large language models within the longer history of computational approaches to analyzing scientific concepts in the history, philosophy, and sociology of science. The study reconstructs computational…

Researchers have introduced Trivium, a causal-memory controller that treats temporal regret—how long a miscalibrated causal model persists—as a first-class objective alongside outcome and epistemic regret. The system add…

Researchers have identified a new failure mode in multi-step agentic retrieval-augmented generation (RAG) systems called cascading hallucination, where errors from early pipeline stages propagate and amplify across reaso…

Researchers introduced the Meta-Agent Challenge (MAC), a new benchmark evaluating whether AI models can autonomously develop agent systems rather than simply execute predefined tasks. Testing showed that meta-agents rare…

Researchers proposed Answer Self-Consistency with Margin-Triggered Question Re-Arbitration (ASC-MQRA) for the CVPR 2026 VidLLMs Challenge Track 2, a training-free test-time reasoning framework that improves video relatio…

Researchers have developed AgentJet, a distributed swarm training framework for large language model agent reinforcement learning that decouples agent rollouts from model optimization across multi-node GPU clusters. The …

Researchers have extended refusal steering methods to Mixture-of-Experts (MoE) large language models, demonstrating that steering vectors can effectively suppress safety-aligned refusal behavior in these architectures. T…
