Focus method enhances LLM attention efficiency without performance loss

Researchers have developed a new method called Focus, designed to improve the efficiency of attention mechanisms in large language models. Standard attention scales quadratically with sequence length, leading to high computational costs. Focus introduces a small number of learnable centroids that act as gates, allowing only relevant token pairs to attend to each other over long ranges. This approach has shown to maintain or even improve performance on downstream tasks and perplexity benchmarks across various model sizes, while significantly increasing processing speed. AI
