title: Covert Perceptual Capability Development creator: Huang, Xiao creator: Weng, Juyang subject: Statistical Models subject: Machine Learning subject: Robotics description: In this paper, we propose a model to develop robots’ covert perceptual capability using reinforcement learning. Covert perceptual behavior is treated as action selected by a motivational system. We apply this model to vision-based navigation. The goal is to enable a robot to learn road boundary type. Instead of dealing with problems in controlled environments with a low-dimensional state space, we test the model on images captured in non-stationary environments. Incremental Hierarchical Discriminant Regression is used to generate states on the fly. Its coarse-to-fine tree structure guarantees real-time retrieval in high-dimensional state space. K Nearest-Neighbor strategy is adopted to further reduce training time complexity. publisher: Lund University Cognitive Studies contributor: Berthouze, Luc contributor: Kaplan, Frédéric contributor: Kozima, Hideki contributor: Yano, Hiroyuki contributor: Konczak, Jürgen contributor: Metta, Giorgio contributor: Nadel, Jacqueline contributor: Sandini, Giulio contributor: Stojanov, Georgi contributor: Balkenius, Christian date: 2005 type: Conference Paper type: PeerReviewed format: application/pdf identifier: http://cogprints.org/4981/1/huang.pdf identifier: Huang, Xiao and Weng, Juyang (2005) Covert Perceptual Capability Development.
