It is motivated by the smoothness of graph signal which will reach a lower bound when samples from the same cluster merge into one component of a graph. We mimic the merging process by using some dynamic clients to represent original samples. The dynamic nature of representatives also reduces to a dynamic graph which endows the final stable graph a lower smoothness, whereas the previous work robust continuous clustering (RCC) uses a fixed graph. This dynamic process is realized by alternatively optimizing the representatives and weights of the graph. We perform experiments on two public database COIL20 and MNIST to demonstrate that the dynamically shrinking of the graph is able to promote the clustering performance.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124179352","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}

Since several parameters are necessary to determine the orthogonality of such transforms, we conducted numerical experiments to determine the optimal parameter for minimizing distortion errors in nonlinear image approximations.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131314768","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}

To explore an effective solution, this paper proposes the Siamese Parallel Fully-connected Neural Network (SPFCNN) as a binary classifier and uses the SMOTE method to deal with the problem of class-unbalanced data distribution. Given that classified cases naturally come with costs, cost-sensitive learning is used to improve the performance of the proposed SPFCNN. An extensive computational study is also performed on cost-sensitive SPFCNN, and the results show that the performance of the proposed approach is better than that of the comparison methods.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133216837","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}

In the solar industry, the prediction of the solar irradiation intensity is an important procedure during the photovoltaic power generation. But sometimes the solar data, which could be used to predict the future power generation case and hold the economic operation, is difficult to capture because the actual geographical environment, where is not allowed to put up the sensor. In order to solve this dilemma, this paper proposes a method of the data generation, which mainly consist of three factors. Through the comparison of the actual solar irradiation intensity data and the generated data with the method, the error is in the permitted range, which means the validity of the method.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115100601","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}

In this paper, a modified U-Net-based method is proposed by combining with Recurrent Residual Convolutional Units (RRCU) and Dilated Convolution. In our method, we achieve higher accuracy by three enhancements. Firstly, replace the basic 3x3 convolution blocks with RRCU. Secondly, replace the 3x3 convolution bottle neck block with multi-ways concatenation. Lastly, replace the max pooling operation with dilated convolution between upper and lower levels. In experiment, the performance of the proposed modified U-Net network is proved to obtain obviously better accuracy than other existing methods in low-light image enhancement.","PeriodicalId":436840,"journal":{"name":"2019 International Conference on Wavelet Analysis and Pattern Recognition (ICWAPR)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134063170","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}
