MaskPro: Linear-Space Probabilistic Learning for Strict (N:M)-Sparsity on LLMs

Yan Sun, Qixin Zhang, Zhiyuan Yu +3

The rapid scaling of large language models~(LLMs) has made inference efficiency a primary bottleneck in the practical deployment. To address this, semi-structured sparsity offers a…

Provable Sparse Inversion and Token Relabel Enhanced One-shot Federated Learning with ViTs

Li Shen, Xiaolei Hao, Qinglun Li +3

One-Shot Federated Learning, where a central server learns a global model in a single communication round, has emerged as a promising paradigm. However, under extremely non-IID set…
