Butterfly matrices

WebAs butterfly matrices are not hardware efficient, we propose simple variants of butterfly (block and flat) to take advantage of modern hardware. Our method (Pixelated Butterfly) uses a simple fixed sparsity pattern based on flat block butterfly and low-rank matrices to sparsify most network layers (e.g., attention, MLP).

WebApr 2, 2016 · For the GPU implementation, we use a recursive butterfly matrix U of depth \(d=2\). Only the diagonal values of the blocks are stored into a vector of size \(2\times N\) as described in . Applying the depth 2 recursive butterfly matrix U consists of multiple applications of depth 1 butterfly matrices on different parts of the matrix A.
