WebProteins Feature extraction Prediction algorithms Optimization Data mining State estimation Evolutionary computation De novo protein structure prediction evolutionary algorithm feature information bisecting K-means algorithm similarity model state estimation WebThe algorithm starts from a single cluster that contains all points. Iteratively it finds divisible clusters on the bottom level and bisects each of them using k-means, until there are k leaf clusters in total or no leaf clusters are divisible. The bisecting steps of clusters on the same level are grouped together to increase parallelism.

WebThe bisecting k-means clustering algorithm combines k-means clustering with divisive hierarchy clustering. With bisecting k-means, you get not only the clusters but also the … WebNov 3, 2016 · It's very interesting that you are getting a giant cluster with 400k entries using bisecting k-means. Bisecting k-means iteratively breaks down the cluster with the highest dissimilarity into smaller clusters. Since you are already producing 100+ clusters, it seems to me that maybe the 400k entry cluster has a very high similarity score.
