FairRAG: Fair Human Generation via Fair Retrieval Augmentation

no code implementations29 Mar 2024 Robik Shrestha, Yang Zou, Qiuyu Chen, Zhiheng Li, Yusheng Xie, Siqi Deng

In this work, we introduce Fair Retrieval Augmented Generation (FairRAG), a novel framework that conditions pre-trained generative models on reference images retrieved from an external image database to improve fairness in human generation.

Semi-Supervised Learning for Anomaly Traffic Detection via Bidirectional Normalizing Flows

1 code implementation13 Mar 2024 Zhangxuan Dang, Yu Zheng, Xinglin Lin, Chunlei Peng, Qiuyu Chen, Xinbo Gao

We consider the problem of anomaly network traffic detection and propose a three-stage anomaly detection framework using only normal traffic.

Adaptive Fractional Dilated Convolution Network for Image Aesthetics Assessment

no code implementations CVPR 2020 Qiuyu Chen, Wei zhang, Ning Zhou, Peng Lei, Yi Xu, Yu Zheng, Jianping Fan

Specifically, the fractional dilated kernel is adaptively constructed according to the image aspect ratios, where the interpolation of nearest two integers dilated kernels is used to cope with the misalignment of fractional sampling.

Deep Boosting of Diverse Experts

no code implementations ICLR 2018 Wei Zhang, Qiuyu Chen, Jun Yu, Jianping Fan

In this paper, a deep boosting algorithm is developed to learn more discriminative ensemble classifier by seamlessly combining a set of base deep CNNs (base experts) with diverse capabilities, e. g., these base deep CNNs are sequentially trained to recognize a set of object classes in an easy-to-hard way according to their learning complexities.
