Deterministic algorithm k-means
WebSince deterministic hierarchical clustering methods are more predictable than -means, a hierarchical clustering of a small random sample of size (e.g., for or ) often provides good … Webtively. In conventional approaches, the LBG algorithm for GMMs and the segmental k-means algorithm for HMMs have been em-ployed to obtain initial model parameters before applying the EM algorithm. However these initial values are not guaranteed to be near the true maximum likelihood point, and the posterior den-
