"WebThe Silhouette Coefficient for a sample is (b - a) / max (a, b). To clarify, b is the distance between a sample and the nearest cluster that the sample is not a part of. Note that Silhouette Coefficient is only defined if number of labels is 2 <= n_labels <= n_samples - 1. This function returns the mean Silhouette Coefficient over all samples.
