Fft winograd
WebJun 21, 2024 · Convolution is a critical component in modern deep neural networks, thus several algorithms for convolution have been developed. Direct convolution is simple but suffers from poor performance. As an alternative, multiple indirect methods have been proposed including im2col-based convolution, FFT-based convolution, or Winograd …

If you want the FFT of a sequence whose length is not a power of 2, and you don't have the machinery for things like the prime-factor algorithm or Winograd's algorithm, there is a method due to Glassman that is often better than actually using the defining sum for DFT. See these three references for details. WebThe main savings in computation in both the Winograd and FFT methods comes from the fact that both the kernel transforms (Wc,c′ ×Nn=1 Gn), and image (tiles) transforms (Ib,c …
