Web16 de set. de 2024 · Such a “long-tailed” (LT) distribution of outcomes can make it challenging to learn discriminative image features, as standard deep image classification methods will be biased toward the common “head” classes, sacrificing predictive performance on the infrequent “tail” classes [ 31 ]. WebTherefore, long-tailed classification is the key to deep learning at scale. However, existing methods are mainly based on re-weighting/re-sampling heuristics that lack a fundamental theory. In this paper, we establish a causal inference framework, which not only unravels the whys of previous methods, but also derives a new principled solution.
