WebOct 26, 2015 · To normalize in [ − 1, 1] you can use: x ″ = 2 x − min x max x − min x − 1. In general, you can always get a new variable x ‴ in [ a, b]: x ‴ = ( b − a) x − min x max x − min x + a. And in case you want to bring a variable back to its original value you can do it because these are linear transformations and thus invertible ...
