Learning from Noisy Labels - - Notes on Machine Learning and Biology Zheltonozhskii et al, 2021 make a nice distinction between self supervised learning (SSL) and learning with noisy labels (LNL). The former, they say, assumes a small quantity of high quality labeled data and a large quantity of unlabeled data of the same distribution. The latter, they say, assumes a large quantity of cheap annotations.

Soon after the introduction of the noise-freePAC model, Angluin and Laird [1988] proposed the random classification noise (RCN) model where each label is flipped independently with some probability ρ∈[0,1/2). How Noisy Labels Impact Machine Learning Models - KDnuggets While this study demonstrates that ML systems have a basic ability to handle mislabeling, many practical applications of ML are faced with complications that make label noise more of a problem. These complications include: Not being able to create very large training sets, and Systematic labeling errors that confuse machine learning.

How to handle noisy labels for robust learning from uncertainty Most deep neural networks (DNNs) are trained with large amounts of noisy labels when they are applied. As DNNs have the high capacity to fit any noisy labels, it is known to be difficult to train DNNs robustly with noisy labels. These noisy labels cause the performance degradation of DNNs due to the memorization effect by over-fitting.

Noisy Labels: Theoretical Approaches/Empirical Studies We demonstrate that several proposed learning-with-noisy-labels solutions in the literature relate closely to negative label smoothing (NLS), which defines as using a negative weight to combine the hard and soft labels. We unify (positive) LS and NLS into GLS, and provide understandings for the properties of GLS when learning with noisy labels.
