We flrst construct a robust classifler combining contributions of a large number of gene expression values, and then search for compact summarizations of subgroups among genes associated in the

The shift in the CIM-software concepts towards both the object-oriented philosophy and the fast-prototyping methodology was simulated by the AI-theoretical backgrounds. The software life cycle models developed in the area of knowledge engineering are compared to the CIM-software development methodologies and the product life

The proposed solutions are based on task decomposition, organization of negotiations, responsibility delegation and other aspects of social behavior in multi-agent systems aimed at integration of already existing software components. It is supposed that all the social knowledge is kept

The system is based on a heterogeneous hierarchy of agents of three types that reflect the managerial structure of the manufacturing enterprise. To improve the system efficiency, a new formalism—called tri-base model—of the multi-agent internal communication/negotiation mechanism has been introduced. The tri-base model

In the paper we present existing solutions of eHealth and ambient assisted living systems developed by researchers of the Faculty of Electrical Engineering of the Czech Technical University in Prague and their industrial partners. We also touch the issue of interoperability that is crucial for correct interconnection

We have focused mainly on knowledge propagation mechanisms. Various types of middle-agents can use these ...
