This paper presents TreeGNG, a top-down unsupervised learning method that produces hierarchical classification schemes.Tree-GNG extends the Growing Neural Gas algorithm by maintaining a time history of the learned topological mapping.TreeGNG is able to recover from poor decisions made during the construction of the tree, and provides the novel ability to influence the general shape of the hierarchy.
