I am happy to announce that the Sparse PCA code has been reviewed and merged into the main scikits.learn repository.

You can use it if you install the bleeding edge scikits.learn git version, by first downloading the source code as explained in the user’s guide, and then running python install.

To see what code is needed to produce an image such as the one above, using scikits.learn. check out this cool decomposition example that compares the results of most matrix decomposition models implemented at the moment.

There are other new cool things that have been recently merged by other contributors, such as support for sparse matrices in minibatch K-means, and the variational infinite gaussian mixture model, so I invite you to take a look!
