WebOct 12, 2024 · My model is in Pytorch 1.2.0 and I have some FFT and IFFT layers in my model which we use to convert our Image to Frequency domain and back. In the Frequency domain we perform some operations to preserve certain frequencies and then use IFFT to convert back to image domain and continue with regular deep learning. Web幸运的是，我们可以利用经典的Cooley-Tukey算法来将FFT的计算分解成一系列smaller blok-level的矩阵相乘的运算来充分利用tensor core。 So we need some way to take advantage of the tensor cores on GPU. Luckily, there’s a classic algorithm called the Cooley-Tukey decomposition of the FFT, or six-step FFT algorithm. pay milwaukee.guardianpharmacy.net
