Author:Boloka, Tlou J; Makondo, N; Rosman, BDate:Jan 2021Deep reinforcement learning has recently been adopted for robot behavior learning, where robot skills are acquired and adapted from data generated by the robot while interacting with its environment through a trial-and-error process. Despite ...Read more
Author:Coetzer, W; Moodley, D; Gerber, ADate:Nov 2014We modeled expert knowledge of arthropod flower-visiting behavioral ecology and represented this in an event-centric domain ontology, which we describe along with the ontology construction process. Two smaller domain ontologies were created ...Read more
Author:Coetzer, W; Moodley, D; Gerber, ADate:Nov 2017Semantic heterogeneity hampers efforts to find, integrate, analyse and interpret ecological data. An application case-study is described, in which the objective was to automate the integration and interpretation of heterogeneous, flower-visiting ...Read more
Author:Parbhoo, C; Moodley, DDate:Mar 2007The discovery, access and sharing of suitable geospatial information in current open and distributed Spatial Data Infrastructures (SDI) still pose a major challenge. These problems usually stem from a lack of consistent semantics that is ...Read more
Author:Stevenson, L; Britz, AA; Home, TDate:Dec 2008The modal satisfiability problem is solved either by using a specifically designed algorith, or by translating the modal logic formula into an instance of a different class of problem, or, more recently, a constraint satisfaction problem. In ...Read more
