Learning From Scratch by Thinking Fast and Slow with Deep Learning and Tree Search

According to dual process theory human reasoning consists of two different kinds of thinking. System 1 is a fast, unconscious and automatic mode of thought, also known as intuition. System 2 is a slow, conscious, explicit and rule-based mode of reasoning that is believed to be an evolutionarily recent process. When learning to complete a challenging planning task, such as playing a board game, humans exploit both processes: strong intuitions allow for more effective analytic reasoning by rapidly selecting interesting lines of play for consideration. Repeated deep study gradually improves intuitions.
