Class "interpolation" (distance to classes)

[tremblap]

@rodrigo.constanzo

Where the big breakthrough came was when @balintlaczko suggested trying to encode the classes as “one-hot” vectors, and operating on that, rather than the descriptors themselves.

you know that this is exactly what the mlpclassifier is doing, and that I shared a patch doing this and sharing it here in April 2022 and pointed at it in May last year? So I wonder what is different now?
