Parallel Projections for Manifold Learning
Harry Strange, Reyer Zwiggelaar · 2010
Manifold learning is a widely used statistical tool which reduces the dimensionality of a data set while aiming to maintain both local and global properties of the data. We present a novel manifold learning technique which aligns local hyper planes to build a global representation of the data. A Minimum Spanning Tree provides the skeleton needed to traverse the manifold so that the local hyper planes can be merged using parallel projections to build a global hyper plane of the data. We show state of the art results when compared against existing manifold learning algorithm on both artificial and real world image data.
