Children Outperform AI in Language Acquisition, Mystery Remains
Human children still learn language with perfect fluency more efficiently than advanced AI models, a phenomenon scientists do not yet fully understand. This highlights a significant gap in current artificial intelligence capabilities compared to biological learning.
Harmony Improves Protein-Ligand Flexible Docking with Torsional Diffusion
Researchers introduce Harmony, a harmonic torsional diffusion framework for flexible protein-ligand docking that explicitly accounts for the periodic geometry of angular variables. This method improves ligand pose accuracy and pocket all-atom reconstruction on benchmarks like PDBBind and enhances the physical validity of generated complexes on PoseBusters.
Multilingual Verifier Bias Impacts RLVR in LLM Mathematical Reasoning
A study reveals that exact-match verifiers in Reinforcement Learning with Verifiable Rewards (RLVR) for Large Language Models (LLMs) exhibit significant language-dependent false-negative reward noise in multilingual mathematical reasoning. This bias, particularly pronounced in Japanese, stems from format and script variations, highlighting a cross-lingual selection bottleneck that impedes effective multilingual LLM training.
