Hi, I have been working as a senior researcher in computer vision and machine learning at the Torr Vision Group (University of Oxford) since 1st March 2019. Prior to that, I was a postdoctoral researcher in the same group from 1st Aug 2016 to 28th Feb 2019. I am also associated with an amazing startup based in Cambridge (U.K.) called FiveAI where we are trying to build driverless cars.
I work in the field of machine learning (optimization, deep learning, generative models etc.) and its applications to vision and language. Please find below few research areas (and related articles) that I am currently excited about.
- Neural Network Discretization: ProxMeanField
- Incremental Learning: RWalk (ECCV18), Tiny Episodic
- Generative Models: MAD-GAN (CVPR18)
- Vision and Language: Flip-Dial (CVPR18), CCA-VD (NIPS-WS18)
- Weakly supervised semantic segmentation: BMVC17, EMMCVPR17
- High-Order Inference: Parsimonious Labeling (ICCV15)
- Structured Prediction: HOAP-SVM (ECCV14), ECCV16, ICML16
Amazing PhD Students I closely work with (jointly with Prof. Philip Torr)
- Arslan Chaudhry (PhD student since Jan 2017)
- Viveka Kulharia (working since September 2017)
- Arnab Ghosh (Intern Jan-July 2017, then joined as a PhD student in TVG)
- Amartya Sanyal (working since August 2018)
- Daniela Massiceti (working since October 2016)
- Jishnu Mukhoti (Internship student since Sept 2018)
I am fortunate to have following amazing external collaborators
