New FourierQK attention mechanism enhances transformer models

Researchers have developed FourierQK, a novel attention mechanism for generative pre-trained transformers that utilizes bandpass-filtered inner products. Experiments on character-level language modeling with TinyShakespeare demonstrated that DC and Nyquist components are detrimental, while an optimal single-scale bandwidth centered around paragraph length (70 tokens) yields significant gains. The study also found that admissible filters, like the Mexican Hat, outperform non-admissible ones and that spectral coverage directly impacts leakage, suggesting FourierQK's effectiveness in bidirectional attention settings such as BERT.
