Episodic memory is the important function of hippocampus, and we can't lack it for our wholesome life. But its theory and role in decision making is not clear yet.

As the result, an association of the episodes and the value enabled rapid action learning with small number of experiences, and takes complementary role with the strong but slow feature of Deep Learning.
