The 13th Annual Workshop on Computational Intelligence will be hosted by the University of Surrey, from September 9-11, 2013. UKCI is the premier UK and Ireland event for presenting leading research on all aspects of computational intelligence. The workshop aims to provide a forum for academic researchers to share research progresses and discuss emerging topics and future directions in the field of computational intelligence. Equally important, this workshop intends to demonstrate successful case studies, identify challenges and bridge the gap between theory and practice in applying computational intelligence to solving real-world problems. The workshop will consist of regular sessions, special sessions and keynote talks from leading researchers in the field of computational intelligence.
