To solve the practical teaching problem of engineering postgraduate students, a Full-chain Innovation Ecological Environment (FIEE) is proposed. FIEE has been constructed by relying on the National Supercomputing Center (NSC) with major scientific research and application projects as driving forces. FIEE is constructed as a three-level practical teaching system, including practical courses pool, integrated practical platforms and domain application innovation platforms. Practical courses have been jointly constructed. Integrated practice platforms consist of common algorithm libraries, general AI software, scientific computing and engineering simulation software. Domain application innovation platforms have been created with a cross-disciplinary and school-enterprise cooperating way. And FIEE is also a double-coupled system, including the supercomputing based virtual simulation part and that of physical instruments, devices and reality platforms. FIEE has chained the whole process of postgraduate training in our college, domain users and even cross-school demonstration units. FIEE has been widely used in our college to systematically train postgraduate students’ abilities of condensing scientific issues, independently engaging in academic research or technological innovation, and cross-disciplinary cooperation. FIEE has also provided innovation training for cross-school students and innovation platforms for domain applications.","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122036860","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}

However, most existing feature selection methods always assume the features have the same cost. These research efforts mainly focus on features’ relevance to learning performance while neglecting the cost to obtain them. Feature cost is a crucial factor need to be considered in feature selection problem especially for the real world applications. For example, in the process of medical diagnosis, each feature may have a very different testing cost. To select low-cost subsets of informative features, in this paper, we propose a stratified random forest-based cost-sensitive feature selection method. Unlike commonly used two-step cost-sensitive feature selection approaches, in our model, the cost of features is incorporated into the construction process of the base decision tree, that is, the cost and the performance of each feature are optimized simultaneously. Moreover, we adopt a stratified sample method to enhance the performance of the feature subset for high-dimensional data. A series of experimental results show that compared with the state-of-the-art methods, the proposed approach can lower the cost of the selected feature subset while maintaining comparable learning performance.","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131513537","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}

Requirements on basic artistic education vary from ages: in the agrarian age, the visual demand for capability of imitative reproduction needed stronger realistic creation ability to lay a better basis; in the industrial age, given the detailed division of sectors, a diversity of basic requirements was raised to facilitate commercial manufacturing; in the information age where we exist at present, unprecedented cross-border integration has been witnessed in various industries and cultures, leading to the deviation of basic requirements from those in previous ages. Therefore, we need a new basic training mode under the general background of new creative & entrepreneurial chain, and training shall be implemented from the core of “training on cognition, development of aesthetic analysis, and elaboration on logic of fine art”. Popular expressions of “BIG DATA”, “Big Data”, “Digitalization” and “Mediatization” are exactly typical characteristics of the age which is now going through information explosion. Regardless of the correctness of such a craze, each of us has actually been involved in this torrent and is hardly possible to stay out of it. Meanwhile, big data and big information are intruding into and changing our lives unexpectedly at an amazing speed. CG (Computer Graphics) has been rapidly popularized and developed in the digital field, and can be considered as having changed all design-related visual languages and existing in every sector of work and life; thus, it has further brought about an adjustment of the entire human educational regime, including reflection and deliberation on basic training for cultivating artistic design talents. What is basic education supposed to be for cultivating design talents under the current situation at this information age? Is there any value of the existence of sketching, known as a core course in the basic education system for design majors and the first course for freshmen who major in design? If so, what are its cultivation mode and system supposed to be? How can we tell its essential difference from the original exam-oriented education? What are its key goals of training? Why does such training have coherency and systematicity with the subsequent curriculum arrangement in sophomore and junior years and in internship and graduation project? Is it substantially divorced from social sectors where graduates are employed? Given similar problems emerging in recent years, is there a need for the reform of sketching systems adopted in all-level educational institutions and universities? How does the reform work? What kinds of design talents are expected? What design qualities are required for designers dealing with information media?Considering aforesaid questions, the author has set the basic teaching mode of arts adopted in the first-line university education for 10 years as a basis, which is essentially different from the original sketching system (including design sketch tutorials and other","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126435253","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 Korea, software education has been introduced for elementary schools that have applied for software education since 2015, and software education has been adopted as a regular subject in all elementary schools since 2017. As the importance of the software industry grows, interest in coding education is increasing. In Korea, students must complete 16 hours of instruction in elementary school and 34 hours in middle school from 2019. In Korea, however, there are not enough professional teachers who majored in software, and many schools have poor laboratory environments. For successful software coding education, a basic hands-on environment should be supported. It is also difficult for the teacher to analyze and score all students’ program sources during class. In this paper, we propose a computer labs management system that can be executed within seconds by using images already generated by Docker for software education at school. And we implemented a programming practice management system using Docker. Our system provides the ability for teachers to automatically identify and score students’ source code as they conduct coding training.","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129524459","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}

However, the increasing density of small cell in UDN brings greater challenge to resource allocation in wireless networks. In order to achieve efficient resource allocation, a many-to-many swap matching (M-MSM) based algorithm of adaptive small cells clustering in ultra-dense networks is proposed in the paper. The many-to-many matching algorithm is utilized to divide the user-centric small cells into different clusters. Meanwhile the matching effect is further optimized by the swap matching algorithm. Simulation results show that the proposed M-MSM algorithm can effectively improve the maximum achievable rate of the UDN.","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132986198","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}

Existing time series prediction algorithms require complex data preprocessing and dynamic feature attribute changes are not supported in these. Based on the above problems, a Dynamic feature-filtering algorithm DFF-TopK (Dynamic Feature filter-TopK) was proposed to reduce the degree of fusion of prior knowledge and support the change of dynamic feature attributes. The algorithm firstly established the initial random forest classifier by directly using the data of all existing features, sorted according to the importance of features. Subsequently, the mapped features are set up as priority queues, and K features with higher priority are selected as input items. When the priority queue length is determined, the importance of input data features within a certain period will be dynamically adjusted along with the priority queue. Furthermore, the influence degree of the upstream and downstream nodes' opening and closing or the dry season and rainy season will be dynamically recognized with the algorithm, which reduces the time complexity and solves the uncertainty caused by a large number of characteristic stacking, and avoids the influence of the traditional prior knowledge division on the results. Compared with the existing global static RF and gradient lifting algorithm DS-TopK, the experiments show that the algorithm has a greater improvement in time complexity and prediction accuracy, which verifies the effectiveness of the algorithm.","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130754212","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}

Information that can be collected in a war environment by soldiers is important information and must reach top-level commanders in time for timely decisions making. Also, ambulance staff in the battlefield need to enter the data of injured soldiers after the first aid, so that the information is available for the field hospital staff to prepare the needs for incoming injured soldiers.In this research, we propose two transaction techniques to handle these issues and use different concurrency control protocols, depending on the nature of the transaction and not a one concurrency control protocol for all types of transactions. Message transaction technique is used to collect valuable data from the battlefield by soldiers and allows top-level commanders to view it according to their permissions by logging into the system, to help them make timely decisions. In addition, use the capabilities of DBMS tools to organize data and generate reports, as well as for future analysis. Medical service unit transactional workflow technique is used to provides medical information to the medical authorities about the injured soldiers and their status, which helps them to prepare the required needs before the wounded soldiers arrive at the hospitals. Both techniques handle the disconnection problem during transaction processing.In our approach, the transaction consists of four phases, reading, editing, validation, and writing phases, and its processing is based on the optimistic concurrency control protocol, and the rules of actionability that describe how a transaction behaves if a value-change is occurred on one or more of its attributes during its processing time by other transactions.","PeriodicalId":351346,"journal":{"name":"2019 14th International Conference on Computer Science & Education (ICCSE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134389013","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}

At this stage, infants' intelligence, physical strength, and psychological development are the fastest, and family education is an indispensable and important link. However, due to irresistible factors such as going out to work, many parents accompany their children for a very limited time or even cannot live together. However, the lack of accompanying children's soul will be hurt, and even affect early education. Therefore, this paper takes \"parent-child accompanying reading\" software as a case study, and proposes a mobile digital early education model based on the Internet and cloud platform, especially for the long-term and short-term left-behind children to provide them with parents' long-distance accompanying reading early education platform. With the rapid development of mobile client and Internet technology, the platform can easily record, broadcast and manage the audio materials of parents' original reading picture books.
