Researchers have developed a new framework called OverRep to address the challenge of knowledge loss during structured pruning of large language models (LLMs). This method, which follows the principle of "train overcomplete, deploy compact," temporarily overparameterizes the recovery module during training to better capture complex knowledge from the original model. After recovery, this overparameterization is merged into a compact module, maintaining the model's original architecture and computational cost. OverRep has demonstrated significant improvements in retained reasoning performance compared to existing recovery methods, especially at higher pruning rates, while keeping memory usage and computational demands comparable.
