The Effects of Mixed Sample Data Augmentation are Class Dependent

no code implementations18 Jul 2023 Haeil Lee, Hansang Lee, Junmo Kim

Mixed Sample Data Augmentation (MSDA) techniques, such as Mixup, CutMix, and PuzzleMix, have been widely acknowledged for enhancing performance in a variety of tasks.

Data Augmentation

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.

Image Classification

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.
