This research introduces ActTail, a clever new method for speeding up Large Language Model (LLM) inference! By smartly allocating activation sparsity, ActTail significantly boosts performance compared to older methods, leading to faster and more efficient LLMs.
Key Takeaways
- •ActTail is a new activation sparsity method designed to speed up LLM inference.
- •It uses a novel approach to allocate sparsity based on the characteristics of Transformer weights.
- •Experiments on LLaMA and Mistral models show significant improvements in perplexity and performance.
