*Who: *         Raymond Yeh, Purdue University

*Title:*          Immunization and Test-Time Augmentation for Pre-Trained
Computer Vision Models
*Abstract:  *With the advancement of open-source pre-trained models,
computer vision systems are built largely by starting from these models
followed by a fine-tuning/adaptation stage. In this context, we explore two
important aspects of pre-trained models: (a) the mitigation of the
potential misuse of pre-trained models, and (b) methods to improve the
performance of a pre-trained model at test time. In this talk, I will
present two recent works from our lab addressing these two topics, namely,
"IMMA: Immunizing Text-to-Image Models Against Malicious Adaptation" and
"Deep Networks with Subsampling Layers Unintentionally Discard Useful
Activations at Test Time."

*Short Bio*: Raymond A. Yeh is an Assistant Professor in Computer Science
at Purdue University. His research focuses on the intersection of machine
learning and computer vision. He develops algorithms to learn effective
computer vision models, with a recent focus on immunizing pre-trained
vision models against fine-tuning and developing vision models with
provable equivariance guarantees. Before joining Purdue, Raymond spent a
year as a research assistant professor at the Toyota Technological
Institute at Chicago (TTIC). He holds a PhD and an M.S. in ECE from the
University of Illinois at Urbana-Champaign (UIUC). Raymond is a recipient
of the Google PhD Fellowship, the Mavis Future Faculty Fellowship, and the
Henry Ford II Scholar Award.
