  • Fitness landscape analysis of weight-elimination neural networks 
    Bosman, Anna; Engelbrecht, Andries P.; Helbig, Marde (Springer, 2018-08)
    Neural network architectures can be regularised by adding a penalty term to the objective function, thus minimising network complexity in addition to the error. However, adding a term to the objective function inevitably ...
  • A simplicial homology algorithm for Lipschitz optimisation 
    Endres, S.C. (Stefan); Sandrock, Carl; Focke, Walter Wilhelm (Springer, 2018-10)
    The simplicial homology global optimisation (SHGO) algorithm is a general purpose global optimisation algorithm based on applications of simplicial integral homology and combinatorial topology. SHGO approximates the homology ...
