20 August 2020 - Yoav Artzi: Seminar

TITLE:    Robot Control and Collaboration in Situated Instruction Following ABSTRACT:

I will present two projects studying the problem of learning to follow natural language instructions. I will present new tasks, a class of interpretable models for instruction following, and learning methods that combine the benefits of supervised and reinforcement learning. In the first part, I will discuss the task of executing natural language instructions with a robotic agent. In contrast to existing work, we do not engineer formal representations of language meaning or the robot environment. Instead, we learn to directly map raw observations and language to low-level continuous control of a quadcopter drone. In the second part, I will propose the task of learning to follow sequences of instructions in a collaborative scenario, where both the user and the system execute actions in the environment and the user controls the system using natural language. To study this problem, we build CerealBar, a multi-player 3D game where a leader instructs a follower, and both act in the environment together to accomplish complex goals.
