Self-attention with linear complexity

WebSep 15, 2024 · Often based on strong mathematical basis, kernelized approaches allow to approximate an attention with linear complexity while retaining high accuracy. The work by Katharopoulos et al. [ 11 ] describes an approximation consisting of computing an attention by a dot product of projected queries and keys. WebIn real-world recommendation systems, the preferences of users are often affected by long-term constant interests and short-term temporal needs. The recently proposed Transformer-based models have proved superior in the sequential recommendation, modeling temporal dynamics globally via the remarkable self-attention mechanism. However, all equivalent …
