OneHotEncoder

[flip111]

I wanted to try rust for some data analysis after getting started with python. In scikit there saw there is a OneHotEncoder which is useful for categorical data. Could such encoder be considered for rusty-machine? I would avoid having to write a bunch of boilerplate code.

By the way, i saw that the rust bindings for tensorflow have an open issue for the same thing https://github.com/tensorflow/rust

The scikit OneHotEncoder is not "the perfect design" in my opinion, but still it's nice to have one :) Perhaps a different design would be more suitable for rusty-machine
