Reinforcement learning via supervised learning

Ziel

The field of machine learning develops learning paradigms and algorithms which allow systems to learn some desired functionality on their own. Supervised learning is learning with a teacher; some authoritative source provides a finite set of correct examples, and the learner generalises from the examples and learns a correct function over the entire spectrum. An example from human learning would be the learning of correct spelling by observing correctly spelled words. Reinforcement learning, on the other hand, is learning by trial and error; there is no teacher and the learner interacts directly with its environment to acquire information. The learner makes decisions arbitrarily and occasionally receives a numerical score (reinforcement signal) for its overall behaviour. This score does not indicate correct or incorrect actions, but can be used to reinforce good decision-making and discourage bad decision-making.

An example from human learning would be the process of learning how to balance and ride a bicycle (falls incur negative scores). These two fields have been researched mostly independently. Recent advances in supervised learning have demonstrated outstanding, near optimal, generalisation performance. Reinforcement learning has not reached the same level of applicability to real-world problems. This research proposal investigates the potential of using supervised learning technology for advancing reinforcement learning. It is possible to incorporate supervised learning algorithms within the inner loops of several reinforcement learning algorithms and therefore reduce one problem to the other. This synergy opens the door to a variety of promising combinations. The proposed research will establish the criteria under which this reduction is possible, will investigate viable combinations, will propose novel algorithms, will assess their potential, and will apply them to real problems of practical interest to demonstrate their effectiveness.
