P-values of one-tailed Wilcoxon tests between the best models trained on each representation. The value in i-th row and j-th column corresponds to the alternative hypothesis saying that the median squared error of i-th representation is greater than the median of j-th representation (superior representations have darker columns, and inferior ones have darker rows). The darkest cells are statistically significant with Bonferroni correction
