Attention Scheme

Attention schemes are computational mechanisms designed to selectively focus on relevant information within large datasets, addressing the computational bottleneck of processing extensive data in tasks like video understanding and natural language processing. Current research emphasizes improving the efficiency of attention, particularly by exploring alternative algorithms to the computationally expensive softmax function, such as polynomial-based approaches and low-rank approximations like incremental SVD, and developing dynamic sparse attention mechanisms. These advancements are crucial for scaling up large language models and improving the performance of various applications, including image generation, text-to-video retrieval, and point cloud analysis, by enabling more efficient processing of complex data.
