WebMar 3, 2024 · To address this issue, we focus on learning robust contrastive representations of data on which the classifier is hard to memorize the label noise under the CE loss. We propose a novel contrastive regularization function to learn such representations over noisy data where label noise does not dominate the representation learning. Weband more robust loss function than the standard loss function (negative log-likelihood) of LR. For example, Pregiobon [15] proposed the following M-estimator: ^ = argmin Xn i=1 ˆ(‘ i( )); where ‘ i() is the negative log-likelihood of the ith sample x iand ˆ() is a Huber type function [8] such as ˆ(t) = ˆ t; if t c; 2 p tc c; if t>c;
