Combined with the results in Table 2, we may infer that to achieve 77.3% accuracy on CTB -test, AL with FA requires 149, 051 × 6.7 = 998, 641.7 seconds of annotation, whereas AL with batch dependency-wise PA needs 56, 389 × 13.6 = 766, 890.4 seconds.
we may roughly say that AL with PA can reduce annotation time over FA by 998,641.7−766,890.4 998,641.7 = 23.2%.
