We then divide this by the covariance matrix (or multiply by the inverse of the covariance matrix). TD3 euclidian ranking. Created by DataCamp.com. See Notes for common calling conventions. I work with L2-normalized vectors, so I wanted to make it faster in cdist by using just dot product instead of cosine, which computes norm as well (which is unit in my case).
