Large-scale image classification using ensembles of nested dichotomies
Ramisa Ayats, Arnau; Torras, Carme (IOS Press, 2013)
Text en actes de congrés
Accés obertMany techniques to reduce the cost at test time in large-scale problems involve a hierarchical organization of classifiers, but are either too expensive to learn or degrade the classification performance. Conversely, in ... -

Text en actes de congrés
Accés obertLocally weighted as well as Gaussian mixtures learning algorithms are suitable strategies for trajectory learning and skill acquisition, in the context of programming by demonstration. Input streams other than visual ... -
Learning inverse kinematics: Reduced sampling through decomposition into virtual robots
Ruiz de Angulo García, Vicente; Torras, Carme (IEEE, 2008)
Article
Accés obertWe propose a technique to speed up the learning of the inverse kinematics of a robot manipulator by decomposing it into two or more virtual robot arms. Unlike previous decomposition approaches, this one does not place any ... -
Learning physical collaborative robot behaviors from human demonstrations
Rozo Castañeda, Leonel; Calinon, Sylvain; Caldwell, Darwin; Jiménez Schlegl, Pablo; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2016-04-01)
Article
Accés obertRobots are becoming safe and smart enough to work alongside people not only on manufacturing production lines, but also in spaces such as houses, museums, or hospitals. This can be significantly exploited in situations in ... -
Learning probabilistic action models from interpretation transitions
Martínez Martínez, David; Ribeiro, Tony; Inoue, Katsumi; Alenyà Ribas, Guillem; Torras, Carme (2015)
Text en actes de congrés
Accés obertProbabilistic planners are very flexible tools that provide good solutions for difficult tasks. However, they rely on a model of the domain and actions, which they have difficulties to learn for complex tasks. We propose ... -
Learning relational dynamics of stochastic domains for planning
Martínez Martínez, David; Alenyà Ribas, Guillem; Torras, Carme; Ribeiro, Tony; Inoue, Katsumi (2016)
Text en actes de congrés
Accés obertProbabilistic planners are very flexible tools that can provide good solutions for difficult tasks. However, they rely on a model of the domain, which may be costly to either hand code or automatically learn for complex ... -
Learning RGB-D descriptors of garment parts for informed robot grasping
Ramisa Ayats, Arnau; Alenyà Ribas, Guillem; Moreno-Noguer, Francesc; Torras, Carme (2014)
Article
Accés obertRobotic handling of textile objects in household environments is an emerging application that has recently received considerable attention thanks to the development of domestic robots. Most current approaches follow a ... -
Learning robot policies using a high-level abstraction persona-behaviour simulator
Andriella, Antonio; Torras, Carme; Alenyà Ribas, Guillem (2019)
Text en actes de congrés
Accés obertCollecting data in Human-Robot Interaction for training learning agents might be a hard task to accomplish. This is especially true when the target users are older adults with dementia since this usually requires hours of ... -
