In this section, we evaluate the effectiveness of the proposed localization method: Vulnerable Block Localization, by investigating whether repairing on the block with the highest block suspiciousness has the best repairing performance. In the following experiments, we apply localization method under different thresholds and models, comparing the results over the accuracy with the models repaired on different blocks. The results show the repairing on the block with the highest block suspiciousness has the highest accuracy, demonstrating our localization method is effective.
