[Feature Request] Add a MinMaxTransform and a MinMaxMeanTransform normalizations ? #709

Open BambOoxX opened 3 years ago

I am very new to this field, so that may be a bad suggestion, but it seems that the most normalization strategies in use are:

Zscore normalization (already implemented)
Unitvector normalization (already implemented)
MinMax normalization i.e. x' = a + (b-a)(x - min(x))/(max(x) - min(x)) over interval [a,b]
MinMaxMean normalization (same than MinMax but with the min(x) in the numerator replaced with mean(x)).

Would you be willing to implement the last two strategies ?

Sure, why not. @wildart What do you think?
