Unsupervised clustering.

14. Check out the DBSCAN algorithm. It clusters based on local density of vectors, i.e. they must not be more than some ε distance apart, and can determine the number of clusters automatically. It also considers outliers, i.e. points with an unsufficient number of ε -neighbors, to not be part of a cluster.

HDBSCAN is the best clustering algorithm and you should always use it. Basically all you need to do is provide a reasonable min_cluster_size, a valid distance metric and you're good to go. For min_cluster_size I suggest using 3 since a cluster of 2 is lame and for metric the default euclidean works great so you don't even need to mention it.Explore and run machine learning code with Kaggle Notebooks | Using data from Wine Quality DatasetIntroduction.
