bioRxiv preprint, 2026

We introduce DODock and DOScore, docking and scoring ML/physics hybrid frameworks that are also highly expressive, yet generalize much better out of distribution compared with the prior ML approaches.

Multi-Concept T2I-Zero: Tweaking Only The Text Embeddings and Nothing Else

Multi-Concept T2I-Zero: Tweaking Only The Text Embeddings and Nothing Else

Hazarapet Tunanyan, Dejia Xu, Shant Navasardyan, Zhangyang Wang, and Humphrey Shi

Arxiv preprint, 2023

In this work, we consider a more ambitious goal: natural multi-concept generation using a pre-trained diffusion model, and with almost no extra cost.

Specialist Diffusion: Plug-and-Play Sample-Efficient Fine-Tuning of Text-to-Image Diffusion Models to Learn Any Unseen Style

Haoming Lu, Hazarapet Tunanyan, Kai Wang, Shant Navasardyan, Zhangyang Wang, and Humphrey Shi

IEEE / CVF Computer Vision and Pattern Recognition Conference (CVPR), 2023

In this paper, we aim to learn an unseen style, so that the fine-tuned model can generate high-quality images of arbitrary objects in this style.
