Learning to Map Natural Language Instructions to Physical Quadcopter Control using Simulated Flight

Understand

We propose a joint simulation and real-world learning framework for mapping navigation instructions and raw first-person observations to continuous control.

• Our model estimates the need for environment exploration, predicts the likelihood of visiting environment positions during execution, and controls the agent to both explore and visit high-likelihood positions.
• We introduce Supervised Reinforcement Asynchronous Learning (SuReAL).
• Learning uses both simulation and real environments without requiring autonomous flight in the physical environment during training, and combines supervised learning for predicting positions to visit and reinforcement learning for continuous control.
