Is Mutual Information(MI) an important factor to consider in unsupervised learning (Clustering)?

I have a supervised learning problem. The final step in the solving process is segmentation. Do features with the lowest MI affect the clustering process?

My problem about Churn Customers Segmentation: I found out some features with no MI at all. Do I drop these features?

Solution

  • You should do a feature important experiment, like this.

    When you know what your X-variable is, you can run some clustering exercises.
