Probabilistic Decoupling of Labels in Classification

16 Jun 2020  ·  Jeppe Nørregaard, Lars Kai Hansen ·

In this paper we develop a principled, probabilistic, unified approach to non-standard classification tasks, such as semi-supervised, positive-unlabelled, multi-positive-unlabelled and noisy-label learning. We train a classifier on the given labels to predict the label-distribution. We then infer the underlying class-distributions by variationally optimizing a model of label-class transitions.
