Abstract
A method of reducing a dimensionality of a dataset is disclosed. The method comprises: calculating an interpolation matrix based on a Laplacian eigenbasis matrix of a sparse representation of the dataset; applying multidimensional scaling (MDS) to a transformation matrix of the interpolation matrix, thereby providing a reduced dataset; and storing the reduced dataset is a computer readable medium.
