The confusion curves compared to the exponent of relaxation a The confusion curves (classifier accuracy as a function of chosen threshold ρp) of different dislocation structure descriptors reach a maximum at the same ρp. For these curves, the used number of PCs was 5 for junctions and GND density, and 10 for correlations. The error bars represent the standard deviation of classifier accuracy in 2-fold cross validation. b The maximum accuracy coincides quite well with the change in the relaxation rate, depicted by the exponent θ of power-law part in the strain rate curves of Fig. 2
