Reinforcement learning for robot control using probability density estimations
Agostini, Alejandro Gabriel; Celaya Llover, Enric (INSTICC Press. Institute for Systems and Technologies of Information, Control and Communication, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialThe successful application of Reinforcement Learning (RL) techniques to robot control is limited by the fact that, in most robotic tasks, the state and action spaces are continuous, multidimensional, and in essence, too ... -
Reinforcement learning with a Gaussian mixture model
Agostini, Alejandro Gabriel; Celaya Llover, Enric (2010)
Text en actes de congrés
Accés obertRecent approaches to Reinforcement Learning (RL) with function approximation include Neural Fitted Q Iteration and the use of Gaussian Processes. They belong to the class of fitted value iteration algorithms, which use a ... -
Robot task specification and execution through relational positioning
Rodríguez Tsouroukdissian, Adolfo; Basañez Villaluenga, Luis; Celaya Llover, Enric (IFAC, 2007)
Text en actes de congrés
Accés obertThis paper presents a relational positioning methodology for flexibly and intuitively specifying offline programmed robot tasks, and for assisting the execution of teleoperated tasks featuring precise or repetitive movements. ... -
Second order collocation
Celaya Llover, Enric (2021)
Report de recerca
Accés obertCollocation methods for optimal control commonly assume that the system dynamics is expressed as a first order ODE of the form dx/dt = f(x, u, t), where x is the state and u the control vector. However, in many cases, the ... -
Solution intervals for variables in spatial RCRCR linkages
Celaya Llover, Enric (2019-03-01)
Article
Accés obertAn analytic method to compute the solution intervals for the input variables of spatial RCRCR linkages and their inversions is presented. The input-output equation is formulated as the intersection of a single ellipse with ... -
Stochastic approximations of average values using proportions of samples
Agostini, Alejandro Gabriel; Celaya Llover, Enric (2011)
Report de recerca
Accés obertIn this work we explain how the stochastic approximation of the average of a random variable is carried out when the observations used in the updates consist in proportion of samples rather than complete samples. -
Visually-guided robot navigation: from artificial to natural landmarks
Celaya Llover, Enric; Albarral Garcia, Jose Luis; Jiménez Schlegl, Pablo; Torras, Carme (2007)
Text en actes de congrés
Accés obertLandmark-based navigation in unknown unstructured environments is far from solved. The bottleneck nowadays seems to be the fast detection of reliable visual references in the image stream as the robot moves. In our research, ... -
