The following steps need to be taken to normalize image pixels: Scaling pixels in the range 0-1 can be done by setting the rescale argument by dividing pixel’s max value by pixel’s min value: 1/255 = 0.0039. Creating iterators using the generator for both test and train datasets. biology tissue examples

"Web26 de set. de 2024 · 1 Answer. The reason for normalization is so that no feature overly dominates the gradient of the loss function. Some algorithms are better at dealing with unnormalized features than others, I think, but in general if your features have vastly different scales you could get in trouble. So normalizing to the range 0 - 1 is sensible. " - Normalization range in ml
