Scaling features for neural network input I have a df with many features that take both negative and positive values.For example a feature may have values in range (-10 , 10).For each feature which has negative values the negative sign means direction and this -10 is actually a larger value than - 5.
After finilizing my model i tried many scaling techniques such as Minmaxscaler from (0,1) and mean max scaler from (-1,1),robust scaler,standarization and found the minmaxscaler from (0,1) has the best results.
My concern is this:
Scaling the data with this technique does not account for the true meaning of my feature as seen belo and -2 will be smaller than -1 after scaling to (0,1).
Is there a way to enforce this rule(negative means only direction) during my scaling process?

Peculiar to your case, you can scale the absolute values of your features, and then apply your directions, i.e. some sort of magnitude scaling, though I'm not sure it'll provide you performance uplift. In addition, don't expect properties like zero mean, unit variance etc. after performing the scaling this way.
