WebFeb 1, 2024 · Self-attention operates over sequences in a step-wise manner: At every time-step, attention assigns an attention weight to each previous input element (representation of past time-steps) and uses these weights to compute the representation of the current time-step as a weighted sum of the past input elements (Vaswani et al., 2024 ). WebAug 1, 2024 · Improvement of self-attention computational complexity. As mentioned in Section 3.3, the ProbSparse self-attention mechanism reduces the time complexity from O n 2 to O n log n compared with the original method. This results in significant performance improvement when dealing with large-scale inputs.
