Molding the Knowledge in Modular Neural Networks

Problem description. The learning of monolithic neural networks becomes harder with growing network size. Likewise the knowledge obtained while learning becomes harder to extract. Such disadvantages are caused by a lack of internal structure, that by its presence would reduce the degrees of freedom in evolving to a training target. A suitable internal structure with respect to modular network construction as well as to nodal discrimination is required. Details on the grouping and selection of nodes can sometimes be concluded from the characteristics of the application area; otherwise a comprehensive search within the solution space is necessary

A unifying approach to CoDesign

Basic arguments are described to create a unified CoDesign environment. A unique feature is the use of a single language to describe systems. Different subsets describe hardware, both structure and behavior, as well a software. It vividly shows that software and hardware are much more alike than usually perceived Borders between the different descriptions now become artificial, meaning we can walk much more freely in the design space. Also our tools benefit from the unification, we need fewer of them and they are inherently more general. Recent developments in functional languages, integrating functional and imperative languages, made this approach practical for the first time. The tool we are developing is intended to stimulate rile integration of software and hardware design roofs into genuine CoDesign tools. The use of a modem typed functional language such as Haskell also makes the language into a broad spectrum CoDesign language.</p
