Answer to: Optimizing a Gaussian penalty function for HSL color compatibility in PyTorch/NumPy

User Rep: 21,212
np.exp(- (hue_diff ** 2) / (2 * sigma ** 2)) Here, 2 * sigma ** 2 is a constant for every array value. Is you compiler clever enough to optimize this away? Why not pass it in as a parameter, rather than just sigma?
