Hi Tom, as far as I know this is not implemented in sklearn. I implemented that in another library (https://github.com/AlexanderFabisch/gmr, example: https://github.com/AlexanderFabisch/gmr/blob/master/examples/plot_estimate_gmm.py). The implementation is very simple and not as efficient and usable as sklearn. Maybe we can integrate something like this? The problem is that it does not really work with the standard sklearn interface.
