PropMix: Hard Sample Filtering and Proportional MixUp for Learning with Noisy Labels

1 code implementation22 Oct 2021 Filipe R. Cordeiro, Vasileios Belagiannis, Ian Reid, Gustavo Carneiro

The most competitive noisy label learning methods rely on an unsupervised classification of clean and noisy samples, where samples classified as noisy are re-labelled and "MixMatched" with the clean samples.

Image Classification with Label Noise Learning with noisy labels

LongReMix: Robust Learning with High Confidence Samples in a Noisy Label Environment

1 code implementation6 Mar 2021 Filipe R. Cordeiro, Ragav Sachdeva, Vasileios Belagiannis, Ian Reid, Gustavo Carneiro

Deep neural network models are robust to a limited amount of label noise, but their ability to memorise noisy labels in high noise rate problems is still an open issue.

Self-supervised Mean Teacher for Semi-supervised Chest X-ray Classification

1 code implementation5 Mar 2021 Fengbei Liu, Yu Tian, Filipe R. Cordeiro, Vasileios Belagiannis, Ian Reid, Gustavo Carneiro

In this paper, we propose Self-supervised Mean Teacher for Semi-supervised (S$^2$MTS$^2$) learning that combines self-supervised mean-teacher pre-training with semi-supervised fine-tuning.

A Survey on Deep Learning with Noisy Labels: How to train your model when you cannot trust on the annotations?

no code implementations5 Dec 2020 Filipe R. Cordeiro, Gustavo Carneiro

As deep learning models depend on correctly labeled data sets and label correctness is difficult to guarantee, it is crucial to consider the presence of noisy labels for deep learning training.

EvidentialMix: Learning with Combined Open-set and Closed-set Noisy Labels

1 code implementation11 Nov 2020 Ragav Sachdeva, Filipe R. Cordeiro, Vasileios Belagiannis, Ian Reid, Gustavo Carneiro

In this work, we study a new variant of the noisy label problem that combines the open-set and closed-set noisy labels, and introduce a benchmark evaluation to assess the performance of training algorithms under this setup.
