Title: Evaluating Weakly Supervised Object Localization Methods Right? A Study on Heatmap-based XAI and Neural Backed Decision Tree. Abstract: Choe et al have investigated several aspects of Weakly Supervised Object Localization (WSOL) with only image label. They addressed the ill-posed nature of the problem and showed that WSOL has not significantly improved beyond the baseline method class activation mapping (CAM). We report the results of similar experiments on ResNet50 with some crucial differences: (1) we perform WSOL using heatmap-based eXplanaible AI (XAI) methods (2) our model is not class agnostic since we are interested in the XAI aspect as well. Under similar protocol, we find that XAI methods perform WSOL with very sub-standard MaxBoxAcc scores. The experiment is then repeated for the same model trained with Neural Backed Decision Tree (NBDT) and we found that vanilla CAM yields significantly better WSOL performance after NBDT training.
