WebTip: Clustering, grouping and classification techniques are some of the most widely used methods in machine learning. The Multivariate Clustering and the Spatially Constrained Multivariate Clustering tool also utilize unsupervised machine learning methods to determine natural clusters in your data. These classification methods are considered … Evaluation (or "validation") of clustering results is as difficult as the clustering itself. Popular approaches involve "internal" evaluation, where the clustering is summarized to a single quality score, "external" evaluation, where the clustering is compared to an existing "ground truth" classification, "manual" evaluation by a human expert, and "indirect" evaluation by evaluating the utility of the clustering in its intended application.
