Sean Segal

I'm currently a research scientist at Uber ATG R&D where I work on deep learning research for the development of self-driving cars. I'm also a PhD student in Computer Science at the University of Toronto supervised by Professor Raquel Urtasun.

I obtained my Masters in Computer Science at University of Toronto in 2020, supervised by Professor Raquel Urtasun. Prior to that, I did my Bachelor's at Brown University studying Computer Science and Economics.

Carla RL Gym


GitHub

OpenAI Gym environment for the CARLA self-driving simulator with implementations of multiple common RL baselines (e.g., A2C, ACKTR, PPO). Originally written as part of a final project for Prof. Jimmy Ba’s deep reinforcement learning course. Now has 50+ stars on Github!
