Existing smoothing filter based data cleaning methods seriously alter the data without preserving the original information. And the others such as SCREEN need to be guided by some semantic constraints in specific application scenarios. To improve the usability, we propose a method called TsRss, which is a practical stream data cleaning method based on local shape feature (Shape-Sheet). TsRss is based on the basic idea that data points failing to match its local shape features are more likely to be dirty. To this end, we first study the methods of generating and representing unequal-length Shape-Sheets based on the local shape features. Then the method for finding dirty data via anomaly detection is proposed based on Shape-Sheet. Finally, experiments were conducted on several real datasets. The result showed that TsRss was more practical in use on various types of data, more accurate or more time-saving compared with state-of-the-art methods.","PeriodicalId":137505,"journal":{"name":"2022 Asia Conference on Algorithms, Computing and Machine Learning (CACML)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129322626","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 use some effective evaluation measures to assess the contribution from each input to each output. Clear interpretations of the learned models are revealed, along with intuitive heat-maps for visualization of the connection weights. Furthermore, the proposed methods are applied to infer the inter-well connectivity between the injectors and the producers in reservoir engineering. After training the networks by water injection rate and liquid production rate data, the reservoir connectivity is efficiently characterized with dynamic parameters. To our knowledge, this is the first time to emphasize on special interpretable neural networks to handle this problem.

Recent work has shown that individual models are more vulnerable than ensemble models in adversarial settings. However, we have empirically demonstrated that ordinary integration methods do not always improve the robustness against black-box attacks, which is more common in the physical world. In this paper, we prove that random forest does not effectively defend against adversarial attacks, even if it is highly discrete. The proposed non-gradient based algorithm can be fast implemented and receives binary feature inputs. We experimentally compared the robustness of random forests and SVMs using white-box and black-box assessments respectively, and show that random forests and decision tree are consistently worse than SVMs.","PeriodicalId":137505,"journal":{"name":"2022 Asia Conference on Algorithms, Computing and Machine Learning (CACML)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129842929","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}

Next, the estimated illumination value of scene is used to adjust the multi-scale reflection components of the input image, and to obtain a preliminarily enhanced image.

A large amount of data simulation results found that the EM algorithm has a good effect on the estimation of mixed distribution parameters, with high accuracy and fast convergence. The initial value selection has little effect on the results, and the preliminary derivation process is more complicated; the Nelder-Mead algorithm has a good effect on the estimation of mixed distribution parameters. High precision, fast convergence speed, the initial value selection has a greater impact on the result, the preliminary derivation process is relatively simple, and the application range is wide. When the initial value is close to the peak value of the real data, the parameter estimation effect is better; the two algorithms have poorer effect on the unimodal distribution parameter estimation for the data, and the bimodal distribution parameter estimation effect is better.","PeriodicalId":137505,"journal":{"name":"2022 Asia Conference on Algorithms, Computing and Machine Learning (CACML)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693515","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}
