Grey Wolf Optimizer (GWO) is a new meta-heuristic optimization. It is inspired by the unique predator strategy and organization system of grey wolves. Since the GWO algorithm is easy to fall into local optimum especially when it is used in the high-dimensional data, an improved GWO algorithm combined with Cuckoo Search (CS) is proposed in this paper. By introducing the global-search ability of CS...
Fault isolation is an essential step in multivariate statistical process monitoring, which discovers the cause of the detected fault. The common adopted techniques for fault isolation, such as contribution plots, reconstruction analysis, branch and bound, etc., often suffer from the problems of the smearing effect, insufficient historical fault data, and heavy computational burden. In this paper,...
In order to solve the problem of unsatisfactory results of imbalanced risk prediction on minority class samples, we suggested to adjust the up-sampling approach to be the neighborhood triangular synthetic minority over-sampling technique (NT-SMOTE). The new approach that we add the nearest neighbor idea and the triangular area sampling idea to the SMOTE performed better in dealing with samples of...
With the information from labeled RGB image an unsupervised method based on label transfer technology is proposed for 3D object recognition and segmentation in RGB-D images. We first use scale invariant features extracted from color space to retrieve a set of nearest neighbors of the input image from the labeled image database. Based on the projection matrix between the labeled image and the input...
Acetoin (3-hydroxy-2-butanone) is an important flavor compound, widely existing in dairy products and some fruits. An study has been performed on acetoin production Bacillus subtilis TH-49. The mutant was obtained by treating B. subtilis NT-50-44 with compound mutation and subjecting it to a shake flask fermentation selection procedure. It was proved that the main metabolite produced by mutant strain...
This paper proposes a novel phased array multi-step mixed feed method using Active Mutating Anneal-Genetic Algorithm(AMAGA) based on sorting. It describes phase array antenna ultra low side lobe technique theory and simulation examples in the case of finite TR module number or variety. In comparison with the density weighed method and multi-step amplitude quantization method, the multi-step mixed...
Public parking facility location is a multi-index and multi-restriction problem. Based on the urban parking comprehensive planning and parkerspsila behavior decisions, it aims to meet the requirement of the parking service under the constraint of limited resources. Itpsilas not all of the parkers that will choose the nearest parking facilities, but all the demand points in facility that is influenced...
