DisenStudio: Customized Multi-subject Text-to-Video Generation with Disentangled Spatial Control

no code implementations21 May 2024 Hong Chen, Xin Wang, YiPeng Zhang, Yuwei Zhou, Zeyang Zhang, Siao Tang, Wenwu Zhu

To tackle the problems, in this paper, we propose DisenStudio, a novel framework that can generate text-guided videos for customized multiple subjects, given few images for each subject.

Post-training Quantization with Progressive Calibration and Activation Relaxing for Text-to-Image Diffusion Models

no code implementations10 Nov 2023 Siao Tang, Xin Wang, Hong Chen, Chaoyu Guan, Zewen Wu, Yansong Tang, Wenwu Zhu

In this paper, we propose a novel post-training quantization method PCR (Progressive Calibration and Relaxing) for text-to-image diffusion models, which consists of a progressive calibration strategy that considers the accumulated quantization error across timesteps, and an activation relaxing strategy that improves the performance with negligible cost.

Lightweight Diffusion Models with Distillation-Based Block Neural Architecture Search

no code implementations8 Nov 2023 Siao Tang, Xin Wang, Hong Chen, Chaoyu Guan, Yansong Tang, Wenwu Zhu

When retraining the searched architecture, we adopt a dynamic joint loss to maintain the consistency between supernet training and subnet retraining, which also provides informative objectives for each block and shortens the paths of gradient propagation.
