GenMix: Combining Generative and Mixture Data Augmentation for Medical Image Classification

no code implementations31 May 2024 Hansang Lee, Haeil Lee, Helen Hong

This process improves the quality and diversity of synthetic data while simultaneously benefiting from the new pattern learning of generative models and the boundary enhancement of mixture models.

Test-Time Mixup Augmentation for Data and Class-Specific Uncertainty Estimation in Deep Learning Image Classification

no code implementations1 Dec 2022 Hansang Lee, Haeil Lee, Helen Hong, Junmo Kim

Our experiments show that (1) TTMA-DU more effectively differentiates correct and incorrect predictions compared to existing uncertainty measures due to mixup perturbation, and (2) TTMA-CSU provides information on class confusion and class similarity for both datasets.

Noisy Label Classification using Label Noise Selection with Test-Time Augmentation Cross-Entropy and NoiseMix Learning

no code implementations1 Dec 2022 Hansang Lee, Haeil Lee, Helen Hong, Junmo Kim

In the classifier learning, we propose the NoiseMix method based on MixUp and BalancedMix methods by mixing the samples from the noisy and the clean label data.
