X*.txt files represent values in the parameter space.
Y*.txt files represent values in the feature space.

Each row of these file is a different sample in the training dataset.
- Parameters are described as follows:
* First two columns: our reparametrized melanin parameters. They correspond to the values sampled uniformly between 0 and 1.
* Next three columns: the R,TT and TRT lobe width, in radians
* Last column: geometric noise

- Features are described as follow:
* First 150 columns: 50 clusters containing Lab color values. Colors are interleaved.
* Next 50 columns: normalized reweighted pixel count per cluster.

Files naming correspond to hairstyles described in Fig.2 in the paper.
