here is that internalization that our inductive bias than just learning some backbone black box for imitation now she also learns a metric in this abstract space that's useful for reinforced learning in the future so we're comparing us with a reactive imitation learning it just says okay I need to just imitate a sequence of actions but this black box known that doesn't know that when you imitate probably the demonstrator had a goal and you're trying to find something of actions that it keeps that goal so it doesn't have that inductive bias it's
