Figure 1. An object from a low-performing class (Pottedplant),
original image in blue, augmented version in orange. a) Because
of its low-entropy, uncertainty-based AL methods do not label the
image. b) Because of its high confidence, pseudo-label SSL meth-
ods wrongly pseudo-label the image and thus harm the training. c)
Because of its high-inconsistency, consistency-based SSL meth-
ods cannot learn from it. d) Our method selects the image for
labeling and prevents it from getting pseudo-labeled.
