However, most methods rely heavily on music domain knowledge.

They had four primitive actions: north, south, east, and west. Multi-Floor Office is an extension of Office to multiple floors. Pick-up and put-down have the intended effect when appropriate; otherwise they do not change the state. T owers of Hanoi contains four discs of different sizes, placed on three poles. Options generated using alternative methods called primitive actions directly.

Recently, researchers have found that representations learned by large-scale pre-trained language models are useful in various downstream tasks.

Such diversity hampers knowledge sharing, learning, and generalization across tasks and environments.
