Are Label Errors Imperative? Is Confident Learning Useful? Confident learning (CL) is a class of learning where the focus is to learn well despite some noise in the dataset. This is achieved by accurately and directly characterizing the uncertainty of label noise in the data. The foundation CL depends on is that Label noise is class-conditional, depending only on the latent true class, not the data 1. Characterizing Label Errors: Confident Learning for Noisy-Labeled Image ... 2.2 The Confident Learning Module. Based on the assumption of Angluin , CL can identify the label errors in the datasets and improve the training with noisy labels by estimating the joint distribution between the noisy (observed) labels \(\tilde{y}\) and the true (latent) labels \({y^*}\). Remarkably, no hyper-parameters and few extra ... Confident Learning: Estimating Uncertainty in Dataset Labels Confident Learning: Estimating Uncertainty in Dataset Labels. Learning exists in the context of data, yet notions of confidence typically focus on model predictions, not label quality. Confident learning (CL) is an alternative approach which focuses instead on label quality by characterizing and identifying label errors in datasets, based on the principles of pruning noisy data, counting with probabilistic thresholds to estimate noise, and ranking examples to train with confidence. Data Noise and Label Noise in Machine Learning Aleatoric, epistemic and label noise can detect certain types of data and label noise [11, 12]. Reflecting the certainty of a prediction is an important asset for autonomous systems, particularly in noisy real-world scenarios. Confidence is also utilized frequently, though it requires well-calibrated models.
