TL;DR: 1. Take FNet (https://arxiv.org/abs/2105.03824 https://arxiv.org/abs/2105.03824). 2. Replace the fixed (frequency-domain) convolution filter with one that is dynamically computed from the data. 3. Apply non-linear functions to both real and imaginary components, before mapping the convolved data back to the time domain.
