WebMar 9, 2024 · It's naive to assume that data will cluster, just because it has a tendency - the test is mostly useful to detect uniform data. The problem is that it doesn't imply a multimodal distribution. A single Gaussian will have a "clustering tendency" according to Hopkins test. But running cluster analysis on a single Gaussian is pointless. WebDivisive clustering starts from one cluster containing all data items. At each step, clusters are successively split into smaller clusters according to some dissimilarity. Basically this is a top-down version. • Probabilistic Clustering Probabilistic clustering, e.g. Mixture of Gaussian, uses a completely probabilistic approach. 4.
