LEMON: Language-Based Environment Manipulation via Execution-Guided Pre-training

Understand

Language-based environment manipulation requires agents to manipulate the environment following natural language instructions, which is challenging due to the huge space of the environments.

• To address this challenge, various approaches have been proposed in recent work.
• Although these approaches work well for their intended environments, they are difficult to generalize across environments.
• In this work, we propose LEMON, a general framework for language-based environment manipulation tasks.
