UNFORTUNATELY THIS SESSION IS CANCELED

We are Back with BIU AI & ML Learning Club !

On May 5,  Hadar Averbuch-Elor from TAU will give a talk titled : Marrying Vision and Language: A Mutually Beneficial Relationship?

Abstract:

Foundation models that connect vision and language have recently shown great promise for a wide array of tasks such as text-to-image generation. Significant attention has been devoted towards utilizing the visual representations learned from these powerful vision and language models. In this talk, I will present an ongoing line of research that focuses on the other direction, aiming at understanding what knowledge language models acquire through exposure to images during pretraining. We first consider in-distribution text and demonstrate how multimodally trained text encoders, such as that of CLIP, outperform models trained in a unimodal vacuum, such as BERT, over tasks that require implicit visual reasoning. Expanding to out-of-distribution text, we address a phenomenon known as sound symbolism, which studies non-trivial correlations between particular sounds and meanings across languages, and demonstrate the presence of this phenomenon in vision and language models such as CLIP and Stable Diffusion. Our work provides new angles for understanding what is learned by these vision and language foundation models, offering principled guidelines for designing models for tasks involving visual reasoning.

BIO:

Hadar Averbuch-Elor is an Assistant Professor at the School of Electrical Engineering in Tel Aviv University. Before that, Hadar was a postdoctoral researcher at Cornell-Tech, working with Noah Snavely. She completed her PhD in Electrical Engineering at Tel-Aviv University, where she was advised by Daniel Cohen-Or. Hadar is a recipient of multiple awards including the Zuckerman Postdoctoral Scholar Fellowship, the Schmidt Postdoctoral Award for Women in Mathematical and Computing Sciences, and the Alon Scholarship. She was also selected as a Rising Star in EECS by UC Berkeley. Hadar’s research interests lie in the intersection of computer graphics and computer vision, particularly in combining pixels with more structured modalities, such as natural language and 3D geometry.

Venue:

Our new venue is CS Building 503, Seminar Room 226, Sunday, May 5, 12:00 PM.

Refreshments (and not less important, the lecture) are awaiting for you!

Looking forward to seeing you there.
