I am a postdoctoral researcher at University of British Columbia working on neural fields. I am advised by Prof. Kwang Moo Yi and Prof. Andrea Tagliasacchi . I did my Ph.D. at CICS UMass-Amherst. I was advised by Prof. Evangelos Kalogerakis , and Prof. Subhransu Maji . I am broadly interested in the problems at the intersection of computer graphics and machine learning. Currently, I work on Neural Fields and Diffusion Models. During my Ph.D., I worked on learning interpretable and editable representations o
Unsupervised Semantic Correspondence Using Stable Diffusion Eric Hedlin, Gopal Sharma , Shweta Mahajan, Hossam Isack, Abhishek Kar, Andrea Tagliasacchi, Kwang Moo Yi. Arxiv 2023, Webpage Abstract Text-to-image diffusion models are now capable of generating images that are often indistinguishable from real images. To generate such images, these models must understand the semantics of the objects they are asked to generate. In this work we show that, without any training, one can leverage this semantic knowle
