Item Metadata only Adaptive Differential Evolution Applied to Point Matching 2D GIS Data(IEEE, 2015-12-07) Khan, N.; Neri, Ferrante; Ahmadi, SamadThe impetus behind data analytics and integration is the need for greater insight and data visibility, but since a growing share of our data is multimedia, there is a parallel need for methods that can align multimedia data. This paper explores georeferencing, which is used to combine spatial datasets and used here to align map images to 2D GIS models. This paper surveys various approaches for building the key components of a georeferencing solution, notes their strengths and weaknesses, and comments on their trajectory to help orient future work. The implementation presented here uses Hough transforms for feature detection, nearest neighbor correspondences with simplistic similarity measures, and a population based optimizer. The comparison among metaheuristics has shown that Differential Evolution (DE) frameworks appear especially suited for this problem. In particular, the controlled randomization of DE parameters appears to display the best performance in terms of execution time and competitive performance in terms of function evaluations even with respect to more complex memetic implementations.Item Metadata only Analytics of Research Literature Quality through Content and Semantics of the Scholarly Literature(2015) Murtagh, F.; Casey, Arlene; Ahmadi, Samad; Contreras, P.Item Metadata only Applying Ahuja-Orlin's large neighbourhood for constructing examination timetabling solution(2004) Abdullah, S.; Ahmadi, Samad; Burke, E.; Dror, M.Item Metadata only Combining human and machine intelligence to produce effective examination timetables(2002) Cowling, P.

This method enables execution of complex moves for improving an existing solution, while dealing with the challenge of exploring the neighbourhood efficiently. An improvement graph is used in which certain negative cycles correspond to the neighbours; these cycles are explored using a recursive method. We address the problem of applying large neighbourhood structure methods on problems where the cost function is not exactly the sum of independent cost functions, as it is in the set partitioning problem. For computational experiments we use four real world data sets for high school timetabling in the Netherlands and England. We present results of the cyclic transfer algorithm with different settings on these data sets. The costs decrease by 8–28% if we use the cyclic transfers for local optimization compared to our initial solutions. The quality of the best initial solutions are comparable to the solutions found in practice by timetablers.Item Metadata only Delivery of intelligent transport systems through the application of computational intelligence.(2011) Goodyer, E.
