Advanced Computer Architectures (ACA)

The Advanced Computer Architectures Groups major aim is to undertake research into novel computer architectures. To date the Group's work has developed systems such as the Cortex II machine based on neural networks, novel search engines, new types of processors for computers and new ways to make computers recognise people.

Group Aims

The ACA group undertakes research into software and hardware for problems that involve large, complex unstructured data, with a particular emphasis on the use of Neural Networks and applications in Pattern Recognition. We work on the theory and application of novel methods as well as the development of the underlying hardware and software for the systems. The group has a strong theme in eScience and Grids. Many of our approaches are biologically inspired.

The group has strong industrial links supported by a spin off company (Cybula Ltd.) to address and commercialise problems in diverse subject areas including search large data sets & biometrics.
