Table 2.

Classification accuracies for all classifiers and feature sets. Blue/red intensities denote the overestimation/underestimation of the CV techniques compared to the ground truth (G.T.) for k-fold and block columns, and compared to chance ($50\%$) for trial-random k-fold (t.r. k-f) and trial-random block (t.r. bl.) columns. Heat map intensities are calculated separately for the ranges in ${}^1$, ${}^2$, and ${}^3$. Bolded values were found to be significantly different, as per Section 4.2.5.
