Probabilistic Contrastive Learning for Long-Tailed Visual Recognition

1 code implementation11 Mar 2024 Chaoqun Du, Yulin Wang, Shiji Song, Gao Huang

To overcome this obstacle, we propose a novel probabilistic contrastive (ProCo) learning algorithm that estimates the data distribution of the samples from each class in the feature space, and samples contrastive pairs accordingly.

SimPro: A Simple Probabilistic Framework Towards Realistic Long-Tailed Semi-Supervised Learning

1 code implementation21 Feb 2024 Chaoqun Du, Yizeng Han, Gao Huang

Recent advancements in semi-supervised learning have focused on a more realistic yet challenging task: addressing imbalances in labeled data while the class distribution of unlabeled data remains both unknown and potentially mismatched.

Assessing a Single Image in Reference-Guided Image Synthesis

no code implementations8 Dec 2021 Jiayi Guo, Chaoqun Du, Jiangshan Wang, Huijuan Huang, Pengfei Wan, Gao Huang

For Reference-guided Image Synthesis (RIS) tasks, i. e., rendering a source image in the style of another reference image, where assessing the quality of a single generated image is crucial, these metrics are not applicable.
