PASER: Post-Training Data Selection for Efficient Pruned Large Language Model Recovery

Bowei He, Lihao Yin, Hui-Ling Zhen +3

Model pruning is an effective approach for compressing large language models (LLMs). However, this process often leads to significant degradation of model capabilities. While post-…
