A new paper questions the long-standing foundation of neural network pruning, known as oracle pruning. The research, which involved training and analyzing 37,000 models across various architectures and datasets, found that the performance of a pruned model after retraining is negligibly correlated with its performance before retraining. This suggests that current pruning criteria, derived from oracle pruning, may be based on a flawed premise, especially for larger deep learning models. The study proposes that task complexity is a key factor in this invalidity and recommends incorporating the retraining stage when developing new pruning criteria. AI
