Apologies if this has been discussed before, but so far I couldn’t find an answer that answers my “why”. So I have the following transformation:
transformation = transforms.Compose([
transforms.Normalize([0.485, 0.456, 0.406], [0.229, 0.224, 0.225])
Pretty standard. However, I am confused about the negative values. I have been told that I shouldn’t work with negative values. Moreover, this is an example of an image that I get from this transform:
I know that it doesn’t have to make sense to the human eye, but I can’t imagine that the pixel values here are appropriate for a machine learning pipeline.
Could someone explain why this is actually fine to work with (if it is)?
