Rises show once there are 4 weeks of history (from mid-November).
Modeling spatiotemporal coupling is a key challenge in building physical intelligence across scales, from microscopic to macroscopic. Existing models capture such structure broadly through physics-motivated dynamical formulations or learning-motivated architectures. The former…
A 512-expert mixture-of-experts model with half of its experts removed, targeted at code and retaining multimodal capability. 58.4 GB against 354 GB at BF16, an effective 1.89 bits per parameter of the original transformer.
Evaluating recommender systems before deployment requires simulators that remain realistic over long, closed-loop interaction cycles. Current LLM-based agents generally function as surface imitators that generate realistic short-term responses but fail to capture the underlying…
