About this paper
Key takeaways for engineers and specialists include the importance of shifting focus from weight selection to architecture search in network pruning. Training pruned models from scratch can often yield comparable or better results than fine-tuning, particularly for structured pruning methods. Automatic pruning methods offer an efficient way to identify more parameter-efficient network structures, potentially leading to the development of more scalable and powerful deep learning models.
