Leave it to the Specialist: Repair Sparse LLMs with Sparse Fine-Tuning via Sparsity Evolution

Qiao Xiao, Alan Ansell, Boqian Wu +4

Sparse large language models (LLMs) offer an attractive direction toward efficient deployment, but adapting them to downstream tasks remains challenging. The central difficulty is…

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…

Memory-Efficient LLM Training with Dynamic Sparsity: From Stability to Practical Scaling

Qiao Xiao, Boqian Wu, Patrik Okanovic +6

Dynamic Sparse Training (DST) offers a promising paradigm for improving the training and inference efficiency of deep neural networks; however, we find that in large language model…

Batch Matrix-form Equations and Implementation of Multilayer Perceptrons

Wieger Wesselink, Bram Grooten, Huub van de Wetering +2

Multilayer perceptrons (MLPs) remain fundamental to modern deep learning, yet their algorithmic details are rarely presented in complete, explicit \emph{batch matrix-form}. Rather,…
