While the strategy of active vision is well established in early vision, it is not widespread in high-level vision. In this paper we suggest an approach for integrating aspects of active vision into a knowledge-based system. One aspect is the selection of optimal camera actions which are chosen to make the recognition process more reliable and efficient. We integrated such camera actions into o...

This paper proposes a novel approach to knowledge discovery and network adaptation through a high-level ontological and context-based architecture that facilitates information customization and knowledge organization through a longitudinal study of user/network behaviors. The proposed model aims at managing distributed knowledge items through stand-alone computational layers that use ontology t...

The goal of transfer learning is to exploit previous experiences and knowledge in order to improve learning in a novel domain. This is especially beneficial for the challenging task of learning classifiers that generalize well when only few training examples are available. In such a case, knowledge transfer methods can help to compensate for the lack of data. The performance and robustness agai...

The continuous increase of data volumes available from many sources raises new challenges for their effective understanding. Knowledge discovery in large data repositories involves processes and activities that are computational intensive, collaborative, and distributed in nature. The Grid is a profitable infrastructure that can be effectively exploited for handling distributed data mining and ...

when emerging technologies such as search engine marketing (sem) face tasks that require human level intelligence, it is inevitable to use the knowledge repositories to endow the machine with the breadth of knowledge available to humans. keyword suggestion for search engine advertising is an important problem for sponsored search and sem that requires a goldmine repository of knowledge. a recen...
