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.
WebThe ML pipeline starts with downloading the sMRI volumes of ASD and TD subjects provided by ABIDE I dataset , then the preprocessing of the sMRI volumes is performed by Freesurfer V.6.0 [54,55,56,57]. Preprocessing consists of three stages, which are: (i) intensity normalization, (ii) skull stripping, and (iii) brain segmentation.
