Generalized Consistent Multi-Class Classification with Rejection to be Compatible with Arbitrary Losses

2 code implementations Conference 2022 Yuzhou Cao, Tianchi Cai, Lei Feng, Lihong Gu, Jinjie Gu, Bo An, Gang Niu, Masashi Sugiyama

\emph{Classification with rejection} (CwR) refrains from making a prediction to avoid critical misclassification when encountering test samples that are difficult to classify.

Multi-Class Classification from Single-Class Data with Confidences

no code implementations16 Jun 2021 Yuzhou Cao, Lei Feng, Senlin Shu, Yitian Xu, Bo An, Gang Niu, Masashi Sugiyama

We show that without any assumptions on the loss functions, models, and optimizers, we can successfully learn a multi-class classifier from only data of a single class with a rigorous consistency guarantee when confidences (i. e., the class-posterior probabilities for all the classes) are available.

Learning from Similarity-Confidence Data

Weakly supervised learning has drawn considerable attention recently to reduce the expensive time and labor consumption of labeling massive data.

Multi-Complementary and Unlabeled Learning for Arbitrary Losses and Models

no code implementations13 Jan 2020 Yuzhou Cao, Shuqi Liu, Yitian Xu

We first give an unbiased estimator of the classification risk from samples with multiple complementary labels, and then further improve the estimator by incorporating unlabeled samples into the risk formulation.
