Aayush Bansal

I am a PhD student (2015-) at the Robotics Institute of Carnegie Mellon University, where I am supervised by Deva Ramanan and Yaser Sheikh. I received my Masters (2013-15) under Abhinav Gupta. At CMU, I have also worked with Daniel Huber on real-time systems and robotic applications. Prior to joining CMU as a graduate student, I worked with Devi Parikh. I did my undergrad in ECE from University of Delhi in 2011.

I had a joyful summer (2017) working with the amazing Shugao Ma, and my advisor, Yaser Sheikh, at Oculus Research in Pittsburgh. Previously, I spent a wonderful summer (2015) working with Bryan Russell at Adobe Research in San Francisco.

I received the prestigious Qualcomm Fellowship for 2017-18, an Uber Presidential Fellowship for 2016-17, and named a Presidential Fellow at CMU.

teaser_mid-obj

Mid-level Elements for Object Detection
Aayush Bansal, Abhinav Shrivastava, Carl Doersch, Abhinav Gupta
arXiv / analysis

We proposed an object detection approach using HoG-based mid-level elements. Without using any contextual reasoning and external data, this method achieved a mean average precision (mAP) of 41.9 on PASCAL VOC 2007, and mAP of 37.1 on VOC 2010. This is comparable to existing state-of-the-art techniques on comp-3 evaluation.

teaser_failure-modes

Towards Transparent Systems: Semantic Characterization of Failure Modes
Aayush Bansal, Ali Farhadi, Devi Parikh
European Conference on Computer Vision (ECCV), 2014
project page / supplementary material

We proposed an approach that identifies patterns in failures and summarizes them with a human understandable characterization using attributes.

teaser_localization
