On the Dynamics Under the Unhinged Loss and Beyond

no code implementations13 Dec 2023 Xiong Zhou, Xianming Liu, Hanzhang Wang, Deming Zhai, Junjun Jiang, Xiangyang Ji

In this paper, we introduce the unhinged loss, a concise loss function, that offers more mathematical opportunities to analyze the closed-form dynamics while requiring as few simplifications or assumptions as possible.

Backdoor Attacks Against Incremental Learners: An Empirical Evaluation Study

no code implementations28 May 2023 Yiqi Zhong, Xianming Liu, Deming Zhai, Junjun Jiang, Xiangyang Ji

Large amounts of incremental learning algorithms have been proposed to alleviate the catastrophic forgetting issue arises while dealing with sequential data on a time series.

Super-Resolving Face Image by Facial Parsing Information

1 code implementation6 Apr 2023 Chenyang Wang, Junjun Jiang, Zhiwei Zhong, Deming Zhai, Xianming Liu

In this paper, we build a novel parsing map guided face super-resolution network which extracts the face prior (i. e., parsing map) directly from low-resolution face image for the following utilization.

Prototype-Anchored Learning for Learning with Imperfect Annotations

no code implementations23 Jun 2022 Xiong Zhou, Xianming Liu, Deming Zhai, Junjun Jiang, Xin Gao, Xiangyang Ji

We verify the effectiveness of PAL on class-imbalanced learning and noise-tolerant learning by extensive experiments on synthetic and real-world datasets.

Learning Towards the Largest Margins

no code implementations ICLR 2022 Xiong Zhou, Xianming Liu, Deming Zhai, Junjun Jiang, Xin Gao, Xiangyang Ji

One of the main challenges for feature representation in deep learning-based classification is the design of appropriate loss functions that exhibit strong discriminative power.

Learning with Noisy Labels via Sparse Regularization

1 code implementation ICCV 2021 Xiong Zhou, Xianming Liu, Chenyang Wang, Deming Zhai, Junjun Jiang, Xiangyang Ji

In this paper, we theoretically prove that \textbf{any loss can be made robust to noisy labels} by restricting the network output to the set of permutations over a fixed vector.

Rectified Meta-Learning from Noisy Labels for Robust Image-based Plant Disease Diagnosis

no code implementations17 Mar 2020 Ruifeng Shi, Deming Zhai, Xian-Ming Liu, Junjun Jiang, Wen Gao

However, the performance of CNN-based classification approach depends on a large amount of high-quality manually labeled training data, which are inevitably introduced noise on labels in practice, leading to model overfitting and performance degradation.
