%A Xiao Huang %A Juyang Weng %T Covert Perceptual Capability Development %X 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. %K vision-based navigation, incremental hierarchical discriminant regression, K-nearest neighbor Q-learning, developmental robot %P 107-110 %E Luc Berthouze %E Fr?d?ric Kaplan %E Hideki Kozima %E Hiroyuki Yano %E J?rgen Konczak %E Giorgio Metta %E Jacqueline Nadel %E Giulio Sandini %E Georgi Stojanov %E Christian Balkenius %V 123 %D 2005 %I Lund University Cognitive Studies %L cogprints4981
