For transformers with multiple working states and nonlinearity of data, adaptive kernel fuzzy C-means clustering (KFCM) algorithm is used to cluster sample data, each class corresponds to a working state. Then, the kernel principal component analysis (KPCA) is used to obtain projection matrices and anomaly detection limits of various classes. A method for online update of sample data is designed in this paper. Finally, the measured data of the power transformer is used for experiment, and the results are compared with the results obtained by using the conventional KPCA algorithm. The experimental results prove the correctness and effectiveness of the method in this paper.","PeriodicalId":358801,"journal":{"name":"2018 Australian & New Zealand Control Conference (ANZCC)","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124712974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the acquisition of MR images due to the interference of the hardware device and external environment, it introduces a amount of noises, which will affect the clinical accuracy of the diagnosis of the disease. The basic principle of non-local mean filtering is similar to the mean filter, but the non-local mean filter adds the weight value of each point to the calculation, so it can be ensured that when neighboring and very different points are averaged in the box, which also retains a lot of details on the edge of the image, so that the image will look more clear. In this paper, the non-local mean denoising algorithm is compared with three kinds of preserving and denoising algorithms: median filtering, anisotropic diffusion filtering, and bilateral filtering. It is verified that it has good performance in denoising while maintaining the edge, and applied in the denoising of real head MR images.","PeriodicalId":358801,"journal":{"name":"2018 Australian & New Zealand Control Conference (ANZCC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128686962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the disadvantages of the generally used Gabor filter based Competitive Coding method is that it is sensitive to variations caused in image acquisition stage. To handle this problem, researchers have proposed a reconstruction based scheme in original image pixel domain. However, the reconstruction in original image domain may lose much valuable directional information extracted by Gabor filters with different orientations. Compared with the previous methods, in this paper, we propose to perform reconstruction in Gabor filter response domain. For each orientation, we reconstruct the Gabor response of a query image using the responses in the template database. Thus, the directional information contained in the image is fully utilized. Then, we binarize each reconstructed responses for feature coding and matching with the constructed \"mask\", which considers not only the reconstructive error but also the Gabor response in a specific location. The mask can characterize the significance of a specific location along a specific orientation. Finally, by using a score level adaptive binary fusion rule, the matching distances before and after reconstruction are adaptively fused. The experimental results conducted on the benchmark PolyU FKP database show the performance advantage of the presented method.","PeriodicalId":358801,"journal":{"name":"2018 Australian & New Zealand Control Conference (ANZCC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127845009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider four different update rules: birth-death(BD), death-birth(DB), imitation(IM) and pairwise comparison(PC). With the same values of cost and benefit of cooperation, we show that there is a unique stochastically stable equilibrium for evolutionary prisoner’s dilemma on regular graphs. If the benefit-to-cost ratio is larger than k + 2 (k is the degree of a regular graph), the networked game has a higher fraction of cooperators than that for a well-mixed population. Under certain conditions, the lower graph connectivity can lead to the emergence of more cooperators. Besides theoretical analysis, we demonstrate our results through numerical computations and simulations as well.","PeriodicalId":358801,"journal":{"name":"2018 Australian & New Zealand Control Conference (ANZCC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114267945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
