Hi Muller:

You have an excellent web site with advanced topics in ML. However, in the Automatic Feature Selection section, you are missing out on some of the easier tools that do feature selection without having to set the number of features you want to select (which is difficult to do) as well as whether to use forward or backward selection. There is a new python library called featurewiz which avoids both these difficulties. It is fast, effective and easy to use (working just like an scikit-learn estimator). Hence it can be used with the fit and transform methods of sklearn.

I believe your page automatic feature selection could use an explanation of this featurewiz library.

Thanks for your consideration,
Ram
