Same Reward, Different Skills: When Multimodal RL Learns to Look

Reinforcement learning with verifiable rewards (RLVR) improves vision-language benchmark scores even without visual information during training. With images at test, blind-trained models recover roughly half of the real-image gain at 3B and nearly four fifths at 7B. Prolonged real-image training can erode grounding whi...

EEGAgentBench: Benchmarking LLM Agents on Short- and Long-Horizon EEG Analysis

Results demonstrate that EEGAgentBench effectively distinguishes agent capabilities beyond model scale and inference cost, while revealing substantial limitations of current LLM agents in long-horizon EEG analysis, particularly in sustained evidence accumulation and multi-step reasoning.

FLASHand: Feed-forward reLightable and Animatable Single-view Hand Reconstruction

FLASHand is proposed, the first feed-forward relightable and animatable 3D hand reconstruction model from a single RGB image, and introduces a mesh-based disentangled 2D Gaussian splatting hand representation to ensure plausible geometry generation and achieve high-fidelity animation and relighting.
