In order to preserve the local structure of the input data, many dimensionality reduction algorithms are involved in the definition of certain locality in the feature space. Thus local patch selection will directly affect the performance of these algorithms. In this paper, we propose a new method of local patch selection for dimensionality reduction. Specially, we incorporate our method into locality-preserving...
An improved genetic algorithm (Fuzzy Adaptive Simulated Annealing Genetic Algorithm with Gradient direction, GFASAGA) will be proposed in this paper, whose global superlinear convergence properties was analyzed by means by Markov chain etc. Certain fuzzy aeroengine compressor guide vane controller parameters of the regulator were optimized by GFASAGA, standard genetic algorithm (SGA) and customized...
University examination timetabling problem is a complicated, multi-constraint combinatorial optimization problem. The current grouping genetic algorithm could get a better optimistic solution. Although the block encoding technique was applied in, the probabilities of crossover and mutation operation were still based on simple genetic algorithm. So the universality of this algorithm is not very well...
