Ankur Deka

I am an AI Robotics Engineer at Nimble Robotics developing state-of-the-art AI technologies for automating robotic warehouses. Prior to this, I was an AI Research Engineer/Scientist working on Reinforcement Learning for robot navigation and manipulation at Intel Labs in Matthias Mueller's group.

I did my Master's at the Robotics Institute, Carnegie Mellon University (CMU) working on Multi Agent Reinforcement Learning (MARL) and Imitation Learning advised by Prof. Katia Sycara and Prof. Michael Lewis. My Master's thesis is On Combining Reinforcement Learning and Adversarial Training.

I completed my BTech in Electronics and Commmunication Engineering and Computer Science from Indian Institute of Technology (IIT) Guwahati in 2019. I have worked on Socially-Aware robot navigation at ATR IRC Lab, Japan in Dr. Norihiro Hagita's group and on 3D reconstruction and segmentation of medical images at Chubu University, Japan in Prof. Yuji Iwahori's group.

I have received the J N Tata Scholarship for graduate studies and was selected for KVPY (English: Young Scientist Incentive Plan).

I am interested in Artificial Intelligence (AI) agents that can act in the world, learn from their experiences and adapt to changes in the environment. Such versatile agents would ultimately improve the quality of human life - robots would provide relief in disasters, perform daily chores in homes and help perform surgeries. I have explored areas of Reinforcement Learning, Computer Vision, Deep Learning, Probabilistic Modeling and hardware design of mechanisms/electronics.

A new class of RL algorithms that improves Adversarial Imitation Learning by leveraging reward differentiability.

Reinforcement Learning policies trained purely in simulation perform compliant insertion of dishes and cups with noisy observations by leveraging a soft gripper and force feedback.

MARL can generate complex leader-follower multi-robot navigation strategies that hide the leader's identity for defense against enemies.

Complex multi-agent strategies can naturally emerge out of competition between teams.

Learning to detect nuclei boundaries can help improve segmentation.

Proposed an Spatio-Temporal Graph based framework for pedestrian trajectory prediction along with an improved attention model.

Reconstruction of 3D shape of polyp from 2 monocular endoscopy images with unknown transformation.

Sim2Real transfer of low-level control policy for self-driving and drifting using q-learning. The project involved creating a simulation environment and training a policy in simulation, modifying the hardware of an RC car, setting up visual trackers, integrating the system with Robot Operating System (ROS) and finally transferring the simulation policy to the real world.

A ball robot similar to BB8 Droid, that can be wirelessly controlled from a long distance to maneuver. There are no external actuators and the robot looks like a normal ball from the outside.

I was bad at the Chrome browser's dinosaur game, so I made a robot to play it.

I made an image scanner from a broken CD drive.

I made made my first robot, a remote-controller pick and place machine from broken toys.
