摘要

最近的研究揭示了在二元和循环卷积计算中，当离散傅里叶变换（DFT）被哈达玛变换替代时，会出现显著的代数误差。本研究提出了三个关键发现：误差消除机制、误差算子的秩以及对预期误差的对齐标量的影响。这些见解对于提高各种应用中卷积操作的准确性至关重要，特别是在信号处理和机器学习领域。

Recent research has uncovered a significant algebraic error that occurs when the discrete Fourier transform (DFT) is substituted with the Hadamard transform in dyadic and circular convolution computations.
