The traditional load classification method based on user types can not meet the needs of power grid services. Iterative Self-Organizing Data Analysis Algorithm (ISODATA) is an unsupervised learning dynamic clustering algorithm based on statistical pattern recognition. In view of the current problems that the initial clustering number of each algorithm is difficult to take and easy to fall into local optimum, the principle and implementation steps of ISODATA are introduced, and this algorithm is applied to the power load curve clustering. The clustering analysis is combined with specific power load curve samples, and the results prove that the clustering effect is better and the time improvement is larger. ISODATA is compared with the traditional clustering method to compare the clustering effect and the time loss of the algorithm. The results of the comparison experiments show that ISODATA has good clustering effect when applied to power load curve clustering.Isodata-based clustering of power load curves can fine distinguish users and provide decision support and scientific basis for the reliable operation of power system.","PeriodicalId":104366,"journal":{"name":"2022 IEEE 7th International Conference on Smart Cloud (SmartCloud)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132514275","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 grade liver fibrosis, ultrasound gray-scale images and ultrasound elastic images are commonly used in clinical diagnosis to judge the severity of liver fibrosis. However, these two diagnoses methods are often vulnerable to disturbances, such as personal experience or instrument differences. Moreover, these individual differences usually lead to conflicting stand-alone machine learning diagnosis models at each hospital whose medical data are not allowed to share in public due to data privacy. To handle the conflicts among diagnosis models, we propose a federated learning based hierarchical diagnosis method of liver fibrosis by utilizing shear wave elasticity pictures of multiple users across hospitals without sharing the original data. Our method is validated with authentic shear wave elasticity pictures of hepatic fibrosis patients in Shanghai, China. Experimental results show that our method is able to preprocess these shear wave elasticity pictures, train local diagnosis models at each hospital and securely consolidate into a shared global diagnosis model whose accuracy is over 70% with only a small dataset containing a few hundreds of labeled pictures. Our method is expected to further improve in its accuracy with more training samples. Our method would be the first practice based on federated learning in liver fibrosis diagnosis.","PeriodicalId":104366,"journal":{"name":"2022 IEEE 7th International Conference on Smart Cloud (SmartCloud)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129417407","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}

This storage is commonly used for caching, local state tracking, and offline support that allows web applications to work when the web server cannot be contacted. The HTML5 Web Storage is becoming increasingly popular with the majority of new web applications using at least some features provided by this standard. Unfortunately, the local storage provided by HTML5 Web Storage is not entirely secure and does not sufficiently ensure the confidentiality of the user’s data. Encrypting data prior to storage is a common approach to protecting local user data. However, as browser-based applications become more complex and demanding the impact of data encryption may adversely impact application performance. Furthermore, the average web developer is generally not proficient in cryptographic best practices in web applications. First, we provide a simple design approach for encryption of local storage that supports offline web applications. Second, we analyze the impact of various symmetric encryption algorithms and implementations on the performance of the HTML Web Storage API. We show that there are several viable options that will increase the confidentiality and privacy of user data within local storage without imposing significant performance penalties.","PeriodicalId":104366,"journal":{"name":"2022 IEEE 7th International Conference on Smart Cloud (SmartCloud)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114854855","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}

It has become an active research topic to develop the offloading schemes for mobile devices, in which the tasks arriving at the mobile devices may be offloaded to run in the cloud or the edge devices. In this paper, mobile edge cloud systems are considered, which consists of mobile devices, edge devices and the cloud server, and the three-tier offloading schemes are proposed to achieve the optimal task performance in MEC. In the three-tier offloading schemes, the computation tasks arriving at the mobile devices may be offloaded to run on the edge devices while the edge devices may further offload the tasks to the cloud when the edge devices are overwhelmed. In this paper, two task modes are considered: batch mode and streaming mode. For the batch mode (i.e., the tasks arriving at the systems and being processed in batches), the offloading optimization problem is modelled as a Mixed 0-1 Integer Programming problem, aiming to minimizing the makespan of the batch of tasks. For streaming mode (i.e., the tasks arriving at the system continuously), the offloading optimization problem is formulated as a non-linear optimization problem, aiming to minimizing the average response time of a task in the task stream. The extensive experiments have been conducted to demonstrate the effectiveness of the proposed offloading schemes, and the impact of various parameters in the MEC systems is also evaluated.","PeriodicalId":104366,"journal":{"name":"2022 IEEE 7th International Conference on Smart Cloud (SmartCloud)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130671513","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}
