Visual Relations, Relative Attributes and Graph Neural Networks

Speaker: Vikas Singh (Biostats)

Seminar Title: Visual Relations, Relative Attributes and Graph Neural Networks

Date: August 3

Time: 4pm-5pm

Location: SMPH/HSLC Room 1325

Abstract: Exploiting relations between entities within an image or between samples in a set of training examples can be very useful in a number of image interpretation and analysis tasks in computer vision. This can be accomplished using shallow models, deep architectures and/or hybrid formulations that mix and match concepts from both. In this talk, I will describe some of our recent results focused on leveraging such “relational” information for improving the performance of computer vision algorithms for visual relationship learning, semi-supervised learning and relative attribute learning. In this talk, we will first cover the simpler settings where the ideas offer impressive results on standard computer vision problems which provide large training datasets. Then, we will discuss preliminary results on the (more challenging) use cases in medical image analysis including design of clinical trials with moderately sized datasets. If time permits, we will see an overview of some ongoing projects based on extensions/variants of these concepts.
