Bio
I’m the Co-CEO and Co-Founder of Yutori. Almost everything in computing has been reinvented in the last thirty years, except how we interact with the web. It’s still a person, a browser, and endless clicking, scrolling, filling forms, fighting popups and ads. At Yutori, we’re building agents that browse and act on the web for you, autonomously.
During my PhD at Georgia Tech (2016–2020), I did some of the earliest work on agents that can see, talk, and act, e.g. visual chatbots trained with deep reinforcement learning, embodied agents that navigate and answer questions, and attention-based multi-agent communication. My labmates and I also developed Grad-CAM (42k+ citations), a general method for interpreting neural networks. Along the way, I interned at FAIR, DeepMind, and Tesla Autopilot.
My PhD thesis was a runner-up for the 2020 AAAI/ACM SIGAI Doctoral Dissertation Award.
I’ve also spent time at Fundamental AI Research (FAIR) at Meta, where I helped start the Open Catalyst Project (now FAIR Chemistry) to accelerate electrocatalyst discovery. My teammates and I developed large datasets like OC20 and OC22, and state-of-the-art models like GemNet-OC, EquiformerV2, and UMA, which have sped up DFT calculations by over 2000x.
I got my Bachelor’s at IIT Roorkee. On the side, I’ve built aideadlin.es, aipaygrad.es, and other things, and I occasionally dabble in generative art.

Side projects
aipaygrad.es
aipaygrad.es provides statistics of industry job offers in Artificial Intelligence (AI).
All data is anonymous, cross-verified against offer letters and will
hopefully reduce information asymmetry.
aideadlin.es
aideadlin.es is a webpage to keep track of CV/NLP/ML/AI conference deadlines. It's hosted on GitHub, and countdowns are automatically updated via pull requests to the data file in the repo.
neural-vqa-attention
Torch implementation of an attention-based visual question answering model (Yang et al., CVPR16).
The model looks at an image, reads a question, and comes up with an answer to the question and a heatmap of where it looked in the image to answer it.
Some results here.
neural-vqa
neural-vqa is an efficient, GPU-based Torch implementation of the visual question answering model from the NIPS 2015 paper 'Exploring Models and Data for Image Question Answering' by Ren et al.
Erdős
Erdős by SDSLabs is a competitive math learning platform, similar in spirit to Project Euler, albeit more feature-packed (support for holding competitions, has a social layer) and prettier.
graf
graf plots pretty git contribution bar graphs in the terminal.
gem install graf to install.
HackFlowy
Clone of WorkFlowy.com, a beautiful, list-based note-taking website that has a 500-item monthly limit on the free tier :-(. This project is an open-source clone of WorkFlowy. "Make lists. Not war." :-)
AirMaps
AirMaps was a fun hackathon project that lets users navigate through Google Earth with gestures and speech commands using a Kinect sensor. It was the winning entry in Microsoft Code.Fun.Do.
HackView
Another fun hackathon-winning project built during Yahoo! HackU! 2012 that involves webRTC-based P2P video chat, and was faster than any other video chat provider (at the time, before Google launched Hangouts).
8tracks-downloader
Ugly-looking, but super-effective bash script for downloading entire playlists from 8tracks. (Still works as of 10/2016).
