EMP: Enhance Memory in Data Pruning

no code implementations28 Aug 2024 Jinying Xiao, Ping Li, Jie Nie, Zhe Tang

Finally, we propose Enhance Memory Pruning (EMP), which addresses the issue of insufficient memory under high pruning rates by enhancing the model's memory of data, thereby improving its performance.
