Hello! :)

I’m Praveen.

I am a Computer Vison / AI Research Engineer at Neubility, I specialize in developing perception algorithms for self-driving robots. I possess a deep understanding of multiview geometry and a passion for training deep neural networks and optimizing them to make them lightweight.

Previously, I was a Graduate student researcher in Vehicular Intelligence Lab at Korea Advanced Institute of Science and Technology where I pursued M.S. in Future Vehicle Program. My research interests include deep learning, 3D computer vision and autonomous driving. Also, I worked with SL Lumax and SL Corporation as Automotive Software Engineer.

I enjoy videos of 3Blue1Brown and Veritasium.
I love cycling. I’ve completed all the officially listed bicycling paths in Korea and received Cycling Road Grand Slam Award.

  • Won 2nd prize for the Robotics event of Path Finder (Line Follower) in the national level technical symposium VISION 2016 organized by Anna University, Chennai, Apr 2016
  • We are expected to design and build a robot (Autonomous robot) with the given specifications in a Line follower competition. Points are assigned based on time to target, with deviations from the black line’s given path avoided. The robot will encounter various obstacles, zig-zag lines, curve lines, and intersecting lines, and it is expected to reach the target without being misled. We are also expected to program it in a different way in different rounds.
I learned about SVC (Static Variable Compensator). Gained hands-on experience with how the organization compensates reactive power to maintain a good power factor, along with the understanding of circuit breaker operation at high voltage machinery.
