Data Sets: Example Data Sets [Updated on 6/7/11].
I include here data sets from a variety of sources, transformed to Matlab format and typically pre-processed, for use with the Diffusion Geometry Code.
They include variations/subsets of the MNIST data base, CBCL Face Data, Science News articles (prepared by J. Solka), Yale Face B database.
Please refer to the original data on these sites if you plan to use this data, as the parts included here are only for the purpose of running examples with the packages above.
They may be installed in any directory and that directory should be added to the Matlab path, so that the packages above may find them (this works for the most recent versions of Matlab).
