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.
