Abstract:
Latest research in reinforcement learning (RL) has demonstrated an ability to succeed in a few arduous tasks. However, fundamental questions still remain as to how the human brain develops an ability to handle a wide variety of tasks and to learn from only few observations. This talk introduces our research team\u2019s twofold approach to advancing the understanding of human RL, by juxtaposing wisdoms from neuroscience and AI.
The first line of research (AI to brain) examines neural correlates of reinforcement learning, causal inference, and prefrontal meta-control. I will summarize our recent findings to support the view that the brain implements multiple distinctive types of learning and inference: model-based and model-free RL, incremental and one-shot inference. This idea forms a basis for the theory that one of the key functions of human prefrontal cortex is to allocate behavioral control to the brain\u2019s subsystems, placing it as the \u201cprefrontal meta-controller\u201d.
The second line of research (Brain to AI) focuses on brain-inspired RL algorithms. I will then discuss an applicability of RL to engineering and neuroscience: AI-human co-evolution engine and neural experimenter. A detailed insight into these issues not only permits advances in AI, but also helps us understand the nature of human intelligence on a deeper level.<\/p>\n\n\n\n
