A new research paper investigates how the allocation of sparsity in neural networks impacts their ability to recover accuracy after pruning, especially when labeled retraining data is unavailable. The study compares different sparsity allocation methods like ERK and LAMP across various datasets and architectures, finding that the choice of allocation significantly affects post-repair accuracy. Researchers identified a critical transition regime where standard repair methods begin to fail, highlighting the need to jointly consider pruning allocation and repair strategies. AI

Researchers have developed a new method for compressing neural networks called slice-wise feature distillation. This technique breaks down large models into smaller, manageable slices for independent tensorization, which speeds up optimization and improves accuracy recovery compared to traditional global finetuning. The approach has shown promising results on models like ResNet-34 and GPT-2 XL, demonstrating its scalability and effectiveness, especially in distributed computing environments. AI
