[Colloquium] 11/13 Research at TTIC: Greg Shakhnarovich, TTIC

[Mary Marre]

*When: *    Friday, November 13th at noon

*Where:*    TTIC, 6045 S Kenwood Avenue, 5th Floor, Room 526

*Who: *       Greg Shakhnarovich, TTIC

*Title:*   Rich Representations for Parsing Visual Scenes

*Abstract: *
I will describe recent and ongoing work on building and using rich
representations aimed at automatic analysis of visual scenes. In
particular, I will describe methods for semantic segmentation (labeling
regions of an image according to the category it belongs to), and on
semantic boundary detection (recovering accurate boundaries of semantically
meaningful regions, such as those corresponding to objects). We focus on
feed-forward architectures for these tasks, leveraging recent advances in
the art of training deep neural networks. Our idea is to shift the burden
of inducing desirable constraints from explicit structure in the model to
implicit structure inherent in computing richer, context-aware
representations. I will describe experiments on standard benchmark data
sets that demonstrate the success of this approach, as well as some work in
progress.

Joint work with Mohammadreza Mostajabi, Payman Yadollahpour, Harry Yang,
Gustav Larsson, and Michael Maire.

*Research at TTIC Seminar Series*

TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research.  The lectures are intended both for students
seeking research topics and adviser, and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.

To receive announcements about the seminar series, please subscribe to the
mailing list: https://groups.google.com/a/ttic.edu/group/talks/subscribe
