This research aims to enhance noisy label learning using an improved part-level multi-labeling method that addresses performance bottlenecks.
Developed a pre-anchoring filtering mechanism to refine anchor samples before Q computation.
Utilized dynamic instance-specific thresholds to filter out unreliable labels and low-confidence instances.
Enhanced optimization through dynamic loss weighting, shifting supervision from instance-level to part-level labels.
L2 distance between predicted and clean class posteriors reduced by 0.01–0.41, validating the reliable anchor selection strategy.
Achieved classification accuracy of 99.38% on MNIST with 45% noise, indicating significant performance gains.
Demonstrated consistent gains of 1.16–4.82 percentage points over existing methods across three benchmark datasets.
