Author:Ranchod, P; Rosman, Benjamin S; Konidaris, GDate:Oct 2015We present a method for segmenting a set of unstructured demonstration trajectories to discover reusable skills using inverse reinforcement learning (IRL). Each skill is characterised by a latent reward function which the demonstrator is ...Read more
Author:Nortje, R; Britz, K; Meyer, TDate:Dec 2012Modularization is an important part of the modular design and maintenance of large scale ontologies. Syntactic locality modules, with their desirable model theoretic properties, play an ever increasing role in the design of algorithms for ...Read more
Author:Britz, K; Meyer, T; Varzinczak, IDate:Dec 2012One of the most successful approaches to the formalization of commonsense reasoning is the work by Lehmann and colleagues, known as the KLM approach, in which defeasible consequence relations with a preferential semantics are studied. In spite ...Read more
Author:Casini, G; Gerber, A; Meyer, TDate:Oct 2012Conceptual modeling is nowadays mostly done using languages such as Entity-Relationship (ER) Models, Unified Modeling Language (UML), and Object-Role Modeling (ORM). These models are used to depict the ontological organization of relevant ...Read more
