py-sparse-filtering

Python implementation of the Sparse Filtering code by Ngiam et al.

Dependencies

The main code depends on numpy and scipy's optimization toolkit. For the demo you also need matplotlib/pylab for visualization and scipy.io.loadmat for reading in the image data.

The image data is the same as the data used by Jiquan Ngiam et al., and can be downloaded from http://cs.stanford.edu/~jngiam/data/patches.mat.
