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.

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.
