Explicit, friendly keys names for MLhandler configuration

[pratapvardhan]

Should we consider explicit, friendly names in configuration?

• target_column for target_col
• exclude_columns for exclude
• categorical_columns for cats

Consistency is good. *_column as a convention is good.

This is early stages, so it's OK to make backward incompatible changes.

If we adopt some standard (e.g. sklearn), that would be even better. Is there a standard we could adopt @jaidevd / @pratapvardhan?

scikit-learn tends to use X for input columns, y for target. Although, mostly usage is with positional argument and not named. So, X, y is not so widely used aswell.

To exclude or numeric columns in scikit we usually use pipeline steps, with ColumnTransformer, make_column_selector etc.

So not sure, it there's something from scikit that can be used at root configuration.
