SlowGuess/NeurIPS_2023_OCR huggingface dataset:
We plot the distribution of energy scores before and after VRA modification in Figure 5. After using VRA modification, the overlap between the energy scores of ID and OOD data becomes less. This phenomenon indicates that VRA makes it easier to distinguish ID and OOD data.
Figure 5: Distribution of scores before and after variational rectification. We treat ImageNet as ID data and use ResNet-50 as the backbone.
