The learning system is characterized by using a direct policy search method for learning the internal state/action mapping. Policy only algorithms may suffer from long convergence times when dealing with real robotics. In order to speed up the process, the learning phase has been carried out in a simulated environment and, in a second step, the policy has been transferred and tested successfully on a real robot. Future steps plan to continue the learning process on-line while on the real robot while performing the mentioned task. We demonstrate its feasibility with real experiments on the underwater robot ICTINEU AUV" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "IEEE" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1109/IROS.2008.4650873" , "dc.relation.ispartof": "© IEEE/RSJ International Conference on Intelligent Robots and Systems : 2008 : IROS 2008, 2008, p. 3635-3640" , "dc.relation.ispartofseries": "Articles publicats (D-ATC)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Aprenentatge per reforç" , "dc.subject": "Robots autònoms" , "dc.subject": "Autonomous robots" , "dc.subject": "Reinforcement learning" , "dc.title": "Policy gradient based Reinforcement Learning for real autonomous underwater cable tracking" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.identifier.doi": "http://dx.doi.org/10.1109/IROS.2008.4650873" }
