Feature Selection in Python | Machine Learning Basics | Boston Housing Data

YouTube Excerpt: Hey Everyone! I'm a first year machine learning PhD student. My research focuses on recommender systems applications in sports science including case-based reasoning techniques to support marathon runners. I have a YouTube channel about my experience doing a PhD and productivity tips but I also have made a few videos related to my research. This video is about feature selection in Python using an example of a kNN regressor on the Boston Housing Data. There are timestamps in the description as well as the python notebook available for download. I hope this will be of interest to some of you and be sure to subscribe if you would like to see more.
