Plan Arithmetic: Compositional Plan Vectors for Multi-Task Control

Understand

Autonomous agents situated in real-world environments must be able to master large repertoires of skills.

• While a single short skill can be learned quickly, it would be impractical to learn every task independently.
• Instead, the agent should share knowledge across behaviors such that each task can be learned efficiently, and such that the resulting model can generalize to new tasks, especially ones that are compositions or subsets of tasks seen previously.
• A policy conditioned on a goal or demonstration has the potential to share knowledge between tasks if it sees enough diversity of inputs.
