Researchers have developed a new method called Rank-Variance Scores (TRV) to improve the accuracy of importance sampling and data pruning techniques, particularly in scenarios with label contamination. Unlike traditional methods that prioritize high-loss examples which can be corrupted data, TRV uses the ranks of multiple independently trained proxies to identify mislabeled examples. This approach is designed to be more robust to noisy labels and has been shown to outperform random selection and magnitude-based rules in experiments on CIFAR-10 and CIFAR-100 datasets, with a minimal increase in training cost.
