Professional Activities
PhD Student - Computer Science Dept. University of Cambridge (Oct 2019 - Present)
Leveraging the use of semi-supervised learning for image to image translation.
Computer Vision Research Intern - Inception Institute of Artificial Intelligence (Sep 2018 - Sep 2019)
Working on making deep neural networks robust against adversarial attacks.
Computer Vision Research Intern - Indian Institute of Technology, Ropar (Dec 2017 - Mar 2018)
Worked on prediction and localization of student engagement in response to a stimuli video (e-learning environment) from facial expressions using Deep Multi-Instance Learning.
Machine Learning Research Intern - University of Canberra, Australia (Dec 2016 - Feb 2017)
Estimation of Heart rate of different individuals and its variations over the span of video from their facial videos by extracting plethysmograph (PG) signals from green channel of the frames. Considering heart rate as extracted feature, individuals are classified into two categories - healthy controls and depressed patients using a linear SVM classifier.
