Using the left Gram matrix to cluster high dimensional data

Shahina Rahman, Valen E. Johnson, Suhasini Subba Rao

For high dimensional data, where P features for N objects (P >> N) are represented in an NxP matrix X, we describe a clustering algorithm based on the normalized left Gram matrix,…

A Fast Algorithm for Clustering High Dimensional Feature Vectors

Shahina Rahman, Valen E. Johnson

We propose an algorithm for clustering high dimensional data. If $P$ features for $N$ objects are represented in an $N \times P$ matrix $X$ , where $N ≪ P$ , the method is base…
