I am reviewing information for feature selection based in filter methods. I got info (link1, link2, link3, link4, link5) for:
- Numerical input, numerical output
- Categorical input, categorical output
- Numerical input, categorical output
However, I'm having a hard time finding information on:
- Categorical input, numerical output (categorical features in a regression problem.)
I would be grateful if you could pass me information about it, please, or the name of the function that could carry out this task.
