New Prox method boosts LLM efficiency via FFN activation sparsity

Researchers have developed a new training-free method called Prox to improve the efficiency of large language models (LLMs) by sparsifying their feed-forward networks (FFNs). Prox utilizes the intermediate state of SwiGLU activations as a signal for channel selection, which is approximated to reduce computational cost. This approach allows for sparse execution of FFNs without significant degradation in model quality, outperforming existing training-free methods across various LLMs and achieving notable speedups.
