สอบถามเพิ่มเติม

How does the introduction of TaylorShift impact the scalability of Transformer models

TaylorShift significantly impacts the scalability of Transformer models by addressing one of the biggest hurdles in processing long sequences - the quadratic complexity of the attention mechanism. By shifting the self-attention complexity from squared to linear using TaylorSoftmax, TaylorShift enables computing full token-to-token interactions in linear time and space. This reformulation allows for more efficient processing of longer sequences without sacrificing performance. The analytical determination of crossover points where employing TaylorShift becomes more efficient aligns closely with empirical measurements, showcasing its ability to enhance memory efficiency for sequences as short as 800 tokens and accelerate inference for inputs beyond approximately 1700 tokens.
