Difference in Average Precision: Genes Binned by B1 AP. The genes are distributed into 10 bins defined by B1 AP score. Each bin has 450 genes except for the right most bin, which has 617 genes. Average B1 scores for the genes in the bins are shown in square brackets along the X axis. The Y axis depicts the mean difference in AP between a given strategy and B1. Thus for example, for the bin closest to the origin, which has average B1 score of 1.0, B2 degrades performances. On average it brings down AP by 0.06. Bars below the X axis indicate negative effects of ranking and bars above indicate positive effects. The height of the bars indicate the extent of the improvement/drop in performance.
