K-tree is a tree-like clustering algorithm. It is also called tree structure vector quantization (TSVQ). The goal of clustering analysis is in similar group objects. Each K-tree object represents a dimension vector space. All vectors in the tree must be the same number of dimensions. K-tree provides a scalable clustering method combining B+-tree and K cluster algorithms. Clusters can be used to solve signal processing problems, using machine learning, and other environments. It has also recently been used to solve problems in the Wikipedia documentation cluster. K-tree 0 ...
