Figure 2.

HRL representation of the casino task. The top level shows the task of playing a casino, and the bottom level decomposes this task into the subtasks of playing slot machines. Prediction errors under the Outcome Model and Slot-Points Model are shown (in this example, “slot-3” indicates the name of the slot machine just played). Note that the prediction error for playing the left casino and the second slot machine occur simultaneously.
