Metric comparison between the used dataset and the closest values reported in evaluation, both for the MuseGAN baseline and PowGAN.

Values in the ‘Model’ row are better the closer to the ‘Dataset’ row. Notice that both datasets show different metrics due to random sampling, track trimming, and sample rejection, but the error still shows a similar scale, which suggests correct training. For the columns, ‘D’, ‘B’, and ‘G’ correspond to Drums, Bass, and Guitar.
