When Data Is Scarce: Scaling Sparse Language Models with Repeated Training

Boqian Wu, Qiao Xiao, Patrik Okanovic +6

Scaling laws for dense LLMs under infinite data are well explored, but how sparsity interacts with limited data is not. In this work, we study sparse training in data-constrained r…
