hclust

Hierarchical clustering algorithms in JavaScript.

npm i ml-hclust

const { agnes } = require('ml-hclust');

const tree = agnes(data, {
  method: 'ward',
});

AGNES (AGglomerative NESting): Continuously merge nodes that have the least dissimilarity.
DIANA (Divisive ANAlysis): The process starts at the root with all the points as one cluster and recursively splits the higher level clusters to build the dendrogram.
BIRCH (Balanced Iterative Reducing and Clustering using Hierarchies): Incrementally construct a CF (Clustering Feature) tree, a hierarchical data structure for multiphase clustering
CURE (Clustering Using REpresentatives):
CHAMELEON
