Leveraging Gradients for Unsupervised Accuracy Estimation under Distribution Shift

no code implementations17 Jan 2024 Renchunzi Xie, Ambroise Odonnat, Vasilii Feofanov, Ievgen Redko, Jianfeng Zhang, Bo An

Our key idea is that the model should be adjusted with a higher magnitude of gradients when it does not generalize to the test dataset with a distribution shift.

Mitigating Memorization of Noisy Labels by Clipping the Model Prediction

no code implementations8 Dec 2022 Hongxin Wei, Huiping Zhuang, Renchunzi Xie, Lei Feng, Gang Niu, Bo An, Yixuan Li

In the presence of noisy labels, designing robust loss functions is critical for securing the generalization performance of deep neural networks.

Open-Sampling: Exploring Out-of-Distribution data for Re-balancing Long-tailed datasets

3 code implementations17 Jun 2022 Hongxin Wei, Lue Tao, Renchunzi Xie, Lei Feng, Bo An

Deep neural networks usually perform poorly when the training dataset suffers from extreme class imbalance.

Mitigating Neural Network Overconfidence with Logit Normalization

2 code implementations19 May 2022 Hongxin Wei, Renchunzi Xie, Hao Cheng, Lei Feng, Bo An, Yixuan Li

Our method is motivated by the analysis that the norm of the logit keeps increasing during training, leading to overconfident output.

GearNet: Stepwise Dual Learning for Weakly Supervised Domain Adaptation

3 code implementations16 Jan 2022 Renchunzi Xie, Hongxin Wei, Lei Feng, Bo An

Although there have been a few studies on this problem, most of them only exploit unidirectional relationships from the source domain to the target domain.

Open-sampling: Re-balancing Long-tailed Datasets with Out-of-Distribution Data

no code implementations29 Sep 2021 Hongxin Wei, Lue Tao, Renchunzi Xie, Lei Feng, Bo An

Deep neural networks usually perform poorly when the training dataset suffers from extreme class imbalance.

Automatic Online Multi-Source Domain Adaptation

1 code implementation5 Sep 2021 Renchunzi Xie, Mahardhika Pratama

Knowledge transfer across several streaming processes remain challenging problem not only because of different distributions of each stream but also because of rapidly changing and never-ending environments of data streams.

ATL: Autonomous Knowledge Transfer from Many Streaming Processes

2 code implementations8 Oct 2019 Mahardhika Pratama, Marcus de Carvalho, Renchunzi Xie, Edwin Lughofer, Jie Lu

It automatically evolves its network structure from scratch with/without the presence of ground truth to overcome independent concept drifts in the source and target domain.
