Rhythm features

I was able to add some rhythm features to the model. I’m using Thomas Lidy and Andreas Rauber’s Rhythm Histograms (RH), summarizing each histogram (one histogram per song) with four features: mean, median, standard deviation, and (at Thomas’s recommendation) kurtosis. Here’s how the map of the same music library looks now:

You can compare with the last version, before RH features were used:

Unfortunately the Rhythm Histogram code couldn’t open my classical music, so you have to disregard that data (to which I gave the mean value of the rest of the songs’ RH data).

So the main thing that happened here is that the rap music popped out. And perhaps a wee bit the jazz.
