CustomContrast: A Multilevel Contrastive Perspective For Subject-Driven Text-to-Image Customization

no code implementations9 Sep 2024 Nan Chen, Mengqi Huang, Zhuowei Chen, Yang Zheng, Lei Zhang, Zhendong Mao

This misconstruction leads to both overfitting or underfitting of irrelevant and intrinsic attributes of the subject, i. e., these attributes are over-represented or under-represented simultaneously, causing a trade-off between similarity and controllability.

An Effective Deployment of Diffusion LM for Data Augmentation in Low-Resource Sentiment Classification

1 code implementation5 Sep 2024 Zhuowei Chen, Lianxi Wang, Yuben Wu, Xinfeng Liao, Yujia Tian, Junyang Zhong

The potential of the diffusion language model (LM) for textual data augmentation (DA) remains unexplored, moreover, textual DA methods struggle to balance the diversity and consistency of new samples.

DreamIdentity: Improved Editability for Efficient Face-identity Preserved Image Generation

no code implementations1 Jul 2023 Zhuowei Chen, Shancheng Fang, Wei Liu, Qian He, Mengqi Huang, Yongdong Zhang, Zhendong Mao

While large-scale pre-trained text-to-image models can synthesize diverse and high-quality human-centric images, an intractable problem is how to preserve the face identity for conditioned face images.

Towards Accurate Image Coding: Improved Autoregressive Image Generation with Dynamic Vector Quantization

1 code implementation CVPR 2023 Mengqi Huang, Zhendong Mao, Zhuowei Chen, Yongdong Zhang

Existing vector quantization (VQ) based autoregressive models follow a two-stage generation paradigm that first learns a codebook to encode images as discrete codes, and then completes generation based on the learned codebook.
