Quotes: However, Roy's controversial ideas on how the brain works and learns probably won't immediately win over many of his colleagues, who have spent decades teaching robots and artificial intelligence (AI) systems how to think using the classic connectionist theory of the brain. Connectionists propose that the brain consists of an interacting network of neurons and cells, and that it solves problems based on how these components are connected. In this theory, there are no separate controllers for higher level brain functions, but all control is local and distributed fairly equally among all the parts. In his paper, Roy argues for a controller theory of the brain. In this view, there are some parts of the brain that control other parts, making it a hierarchical system. In the controller theory, which fits with the so-called computational theory, the brain learns lots of rules and uses them in a top-down processing method to operate. In his paper, Roy shows that the connectionist theory actually is controller-based, using a logical argument and neurological evidence. He explains that some of the simplest connectionist systems use controllers to execute operations, and, since more complex connectionist systems are based on simpler ones, these too use controllers. If Roy's logic correctly describes how the brain functions, it could help AI researchers overcome some inherent limitations in connectionist algorithms. "Connectionism can never create autonomous learning machines, and that's where its flaw is," Roy told PhysOrg.com. "Connectionism requires human babysitting of their learning algorithms, and that's not very brain-like. We don't guide and control the learning inside our head. etc....
