Summary of algorithm performance.

Δ correlation is computed as the mean difference in correlation coefficient compared to the STM algorithm. Δ var. exp. in % is computed as the mean relative improvement variance explained (r2). Note that since variance explained is a nonlinear function of correlation, algorithms can be ranked differently according to the two measures. All means are taken over N = 32 recordings in the test set, except for training correlation, which is computed over N = 60 recordings in the training set.
