Using correlation matrix for feature selection

Hi @mehmet_baki_deniz

in addition to @Nithin_Skantha_M‘s great feedback.

Here you can also find an example as inspiration also for context and code in this Repo Source.

For example you could apply feature engineering techniques to describe the non-linearity already in your features and check and adapt your feature design based on your visualization. Here also a relevant thread for you:

Hope that helps!
