There is a large gap between current AI systems and human intelligence. We study intelligence with a focus on metacognitive activities while following the recent development of deep learning, and eventually aim at their concrete implementation through three approaches: Introspection, Constructivism and Neuroscience.

Metacognition and Curiosity for Efficient Exploration

Many tasks have sparse rewards in the world. Random exploration for sparse rewards, however, is computationally expensive. A human agent explores the world by seeking sparse rewards efficiently. We focus on metacognition and curiosity as the crucial factors for such efficient explorative strategies. We proposed experience sampling methods to approach metacognition [1,2]. We demonstrated our experience sampling methods to collect introspective experience effiently. We also investigate neural mechanisms of curiosity for such an efficient explorative algorithm and its relation to metacognition.
