Deep Reinforcement Learning Boosted by External Knowledge
Recent improvements in deep reinforcement learning have allowed to solve problems in many 2D domains such as Atari games. However, in complex 3D environments, numerous learning episodes are required which may be too time consuming or even impossible especially in real-world scenarios. We present a new architecture to combine external knowledge and deep reinforcement learning using only visual i...
متن کاملThe detrimental effects of extrinsic reinforcement on "Intrinsic motivation".
Extrinsic consequences have been criticized on the grounds that they decrease intrinsic motivation or internally initiated behavior. Two popular rationales for this criticism, Lepper's overjustification hypothesis (1981) and Deci's motivational theory (Deci & Ryan, 1985), are reviewed and the criticism is then redefined behaviorally. "Intrinsically controlled" behavior is defined as behavior ma...
متن کاملExploring Effects of Intrinsic Motivation in Reinforcement Learning Agents
We explore Intrinsic Motivation as a reward framework for learning how to perform complicated tasks. Most reinforcement learning tasks assume the existence of a critic who rewards the agent for its actions. However, taking inspiration for biological agents, we can say that the real critic is the agent itself. We experiment with a model where the rewards are generated by the agent using a proces...
متن کاملIntrinsic Motivation and Reinforcement Learning
Psychologists distinguish between extrinsically motivated behavior, which is behavior undertaken to achieve some externally supplied reward, such as a prize, a high grade, or a high-paying job, and intrinsically motivated behavior, which is behavior done for its own sake. Is an analogous distinction meaningful for machine learning systems? Can we say of a machine learning system that it is moti...
متن کاملImproving Information Extraction by Acquiring External Evidence with Reinforcement Learning
Most successful information extraction systems operate with access to a large collection of documents. In this work, we explore the task of acquiring and incorporating external evidence to improve extraction accuracy in domains where the amount of training data is scarce. This process entails issuing search queries, extraction from new sources and reconciliation of extracted values, which are r...
