Suspicious examples identified by EIF -- Generalization errors in test set

Generalization errors in testing set

According to the definitions in paper (Section 5.2) , we divide the generalization errors in testing set into 4 categories:

Type I error agreeable confusion pair: Two inter-class samples confuse with each other and human cannot distinguish them

Type II error disagreeable confusion pair: Two inter-class samples confuse with each other but human can distinguish them

Type III error agreeable mis-similar pair: Two intra-class samples far from with each other and human agree they look very different

Type IV error disagreeable mis-similar pair: Two intra-class samples far from with each other and human think they are visually similar

Based on these definitions, we show some examples from each dataset (model is trained with Proxy-NCA++).
