UnverifiedFFT outputs complex values containing magnitude and phase; its magnitude spectrum is inherently shift-invariant, but the phase information is extremely sensitive to shifts.66% similarUnverifiedNTT (Number Theoretic Transform) can reduce the complexity of polynomial multiplication from O(n²) to O(n log n).65% similarUnverifiedFNO transforms the input function to frequency space via Fast Fourier Transform, applies a learnable linear transformation to the low-frequency components, and then transforms back to the spatial domain via inverse FFT.63% similarUnverified规则周期性纹理（如棋盘格）在DCT或傅里叶变换中会产生集中的高频分量，CNN中层卷积核对这类高频周期结构高度敏感，可能导致误判62% similarUnverifiedThe Discrete Fourier Transform (DFT) is a numerical computation version of the continuous Fourier transform, applicable to finite-length sampled data.60% similar
