Debiasing Text-to-Image Diffusion Models

no code implementations22 Feb 2024 Ruifei He, Chuhui Xue, Haoru Tan, Wenqing Zhang, Yingchen Yu, Song Bai, Xiaojuan Qi

Despite its simplicity, we show that IDA shows efficiency and fast convergence in resolving the social bias in TTI diffusion models.

Vertical Layering of Quantized Neural Networks for Heterogeneous Inference

no code implementations10 Dec 2022 Hai Wu, Ruifei He, Haoru Tan, Xiaojuan Qi, Kaibin Huang

Experiments show that the proposed vertical-layered representation and developed once QAT scheme are effective in embodying multiple quantized networks into a single one and allow one-time training, and it delivers comparable performance as that of quantized models tailored to any specific bit-width.

LUMix: Improving Mixup by Better Modelling Label Uncertainty

no code implementations29 Nov 2022 Shuyang Sun, Jie-Neng Chen, Ruifei He, Alan Yuille, Philip Torr, Song Bai

LUMix is simple as it can be implemented in just a few lines of code and can be universally applied to any deep networks \eg CNNs and Vision Transformers, with minimal computational cost.

Re-distributing Biased Pseudo Labels for Semi-supervised Semantic Segmentation: A Baseline Investigation

1 code implementation ICCV 2021 Ruifei He, Jihan Yang, Xiaojuan Qi

In this paper, we present a simple and yet effective Distribution Alignment and Random Sampling (DARS) method to produce unbiased pseudo labels that match the true class distribution estimated from the labeled data.
