VerifiedStandard self-attention has a computational complexity of O(n²); SSA reduces complexity by having each token attend only to the most relevant subset, theoretically compressible to O(n·log n) or even O(n) level.72% similarUnverifiedIn the standard attention mechanism, the Query matrix and Key matrix perform matrix multiplication to obtain an n×n attention score matrix, with a computational complexity of O(n²·d).72% similarVerifiedThe self-attention mechanism allows each position to interact directly with any other position in the sequence, with a computational complexity of O(n²).71% similarVerifiedThe computational complexity of the standard Self-Attention mechanism has a quadratic relationship with sequence length (O(n²)).70% similarVerifiedThe self-attention mechanism allows the model to simultaneously see the information of all other tokens in the input sequence when processing each token, and the computational complexity of the attention matrix is O(n²)68% similar
