Periodic Weak Spots: Phase Sensitivity from Chunked KV-Cache Compression

Xingyu Zhu, Pu, Yi +6

Chunked KV-cache compression reduces the memory and attention costs of long-context inference by compressing windows of consecutive tokens into fewer cache entries at a fixed strid…

LLMs as Noisy Channels: A Shannon Perspective on Model Capacity and Scaling Laws

Xu Ouyang, Deyi Liu, Yuhang Cai +5

Existing scaling laws for Large Language Models (LLMs), predominantly monotonic power laws, fail to explain emerging non-monotonic phenomena such as catastrophic overtraining and q…

Coupling Experts and Routers in Mixture-of-Experts via an Auxiliary Loss

Ang Lv, Jin Ma, Yiyuan Ma +1

Mixture-of-Experts (MoE) models lack explicit constraints to ensure the router's decisions align well with the experts' capabilities, which ultimately limits model performance. To…
