Defining Graph

Neural networks are increasingly becoming a useful and popular choice for process modeling. The success of neural networks in effectively modeling a certain problem depends on the topology of the neural network. Generating topologies manually relies on previous neural network experience and is tedious and difficult. Hence there is a rising need for a method that generates neural network topologies for different problems automatically. Current methods such as growing, pruning and using genetic algorithms for this task are very complicated and do not explore all the possible topologies. This paper presents a novel method of automatically generating neural networks using a graph grammar. The approach involves representing the neural network as a graph and defining graph transformation rules to generate the topologies. The approach is simple, efficient and has the ability to create topologies of varying complexity. Two example problems are presented to demonstrate the power of our approach.

Time Required

This paper deals with the design of a multi-agent system for distributed design. The design processes are often complex and require high computational costs. Yet in many situations many elements of a design process can be computed simultaneously and thus lowering the total time required to finish the design. In this paper an approach based on hypergraph representation and using a formal background of the parallel application of the graph transformation rules is presented (parallel derivation process). The system is illustrated with examples from the floor layout design system.

Architecture Evolution

This chapter presents the concept of graph-based architecture evolution and how this concept can be applied to improve the quality characteristics of a software system. For this purpose, the UML-RT used as an architectural specification language is mapped to a hypergraph-based data structure. Thus, transformation operators can be specified as hypergraph transformation rules and applied automatically.
