Silhouette Score, Inliers, and Outliers

In this video, we tackle the basics of silhouette scores. The silhouette score reports on how central a data point is to its own cluster. We can use silhouette scoring to find inliers and outliers. We begin with a two dimensional example, draw the data, compute the silhouettes and plot them in the Silhouette Plot.
