The traditional principal component analysis method is sensitive to outliers since it is based on the sample covariance matrix. Meanwhile, the deviation of the principal component analysis based on the Minimum Covariance Determinant (MCD) estimation is significantly increased as the data dimension increases. In this paper, we propose a high-dimensional robust principal component analysis based on the Rocke estimator. Simulation studies and a real data analysis illustrate that the finite sample performance of the proposed method is significantly better than those of the existing methods.","PeriodicalId":45004,"journal":{"name":"Journal of Computational Methods in Sciences and Engineering","volume":"23 1","pages":"2303-2311"},"PeriodicalIF":0.5,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70041271","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}

{"title":"Construction of the flipped classroom teaching mode of British and American literature in the context of big data and IoT","authors":"Xiangnan Xu, Shuhui Shi","doi":"10.3233/jcm-226816","DOIUrl":"https://doi.org/10.3233/jcm-226816","url":null,"abstract":"With the advancement of cultural globalization, China has increased its support for the study of British and American literature. However, due to the great differences in the forms of expression and thinking logic between British and American literature and Chinese local literature, it is difficult for Chinese students to learn British and American literature. In order to solve the dilemma of Chinese students learning English and American literature, the team constructed a smart classroom model with flipped classroom as the core based on big data and Internet of Things technology. The smart classroom model is constructed according to the four-layer architecture of the Internet of Things, which is divided into perception layer, network layer, platform layer and application layer. The flipped classroom is in the application layer. The flipped classroom is designed according to the three processes before, during and after class, which has certain theoretical significance. In order to verify the effectiveness of this model, a university in H city was selected for research. Through the control experiment, it was concluded that within a certain error range, the flipped classroom teaching mode can significantly improve the teaching effect of British and American literature compared with the traditional teaching mode. Finally, based on the problems of English and American literature learning, we further deepen the model of flipped classroom. In the pre-course pre-study stage, teachers should play their organizational role and enhance students’ pre-study effect through interesting pre-study methods. Teachers should also pay attention to students’ pre-study status and make timely adjustments. In the classroom, teachers need to find students’ questions in time and answer common questions in a unified manner and answer individual questions in private, in an effort to improve classroom efficiency and promote the process of internalizing students’ knowledge. At the end of the flipped classroom, the classroom should also summarize the lesson, recognize the strengths and weaknesses of the lesson implementation based on the feedback from the students, and clarify the room for improvement of the lesson. At the same time, teachers should also reflect on the flipped classroom model and comprehensively assess its strengths and weaknesses to ensure that this model can be applied to its full value.","PeriodicalId":45004,"journal":{"name":"Journal of Computational Methods in Sciences and Engineering","volume":"23 1","pages":"2451-2461"},"PeriodicalIF":0.5,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70041078","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 context, big data technology has gradually become a type of technology with special value in the field of education. It realizes business decision-making through the collection and analysis of specific types of data. The application of technology to the field of education can realize the analysis of students’ learning needs and classroom teaching efficiency, while the application of big data technology to piano teaching can strengthen the combination of piano teaching and technology, and at the same time provide more data analysis and decision support for the whole process of piano teaching. Soft computing simplifies the calculation process by combining a variety of sophisticated algorithms. Soft computing is similar to human brain processing and perception. It can complete multi-variable complex calculations through low-cost and uncertain processes. With the continuous integration, the variables generated in the teaching process gradually increase, and the application of soft computing technology can effectively solve the complex calculation problems caused by many variables in the analysis of piano teaching. This paper first analyzes the basic theory of big data, soft computing and piano informatization teaching, and then obtains the problems existing in the current piano informatization teaching through questionnaire survey and analysis, and designs piano informatization, teaching innovation model based on big data and soft computing technology respectively. Through the post-investigation of the piano informatization teaching institutions combined with technical strategies, it is found that the degree of match between the piano informatization teaching content of the institution and the students’ learning needs, the evaluation accuracy of piano teachers’ teaching effects, and the students’ piano learning performance have improved.","PeriodicalId":45004,"journal":{"name":"Journal of Computational Methods in Sciences and Engineering","volume":"23 1","pages":"2425-2435"},"PeriodicalIF":0.5,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70040968","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}

The development of big data and the Internet of Things provides a new opportunity to study the impact of parental participation on parent-child sports interaction. This article uses technology to obtain experimental data and analyze the results of the experiment. By studying the four situations of parental participation, single parent participation, and neither parent participating, it is shown in a comparative way that parental participation can significantly improve children’s sense of experience and comprehensive ability in parent-child sports interaction. When one parent participates alone, the effect of the father’s participation is better than that of the mother. Parental participation will make children more interested in sports, and parental participation will also improve children’s abilities in all aspects. Targeted solutions are proposed based on these problems. Let fathers participate more in parent-child sports interaction, strengthen parents’ understanding of parent-child sports interaction, enrich parents’ educational experience, parents should coordinate work and life time, and choose appropriate methods for parent-child sports interaction. At present, although some achievements have been made in parent-child sports interaction, there is still a lot of room for improvement, and further research is needed.","PeriodicalId":45004,"journal":{"name":"Journal of Computational Methods in Sciences and Engineering","volume":"23 1","pages":"2377-2387"},"PeriodicalIF":0.5,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70040778","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}

The rise of big data and the Internet of Things has had an impact on all walks of life. The development of big data and the Internet of Things provides an opportunity for the evolution of street form. With the rapid development of smart cities, the street shape is also changing more and more towards the direction of intelligence. Taking Chunxi Road in Chengdu as an example, this paper studies the generation mechanism of street morphology. The factors influencing the generation of street form are divided into two categories: (1) legal factors. (2) Architectural design factors. By building a model, the article quantitatively analyzes the impact of these two types of factors on street form. At the same time, the article conducts an in-depth study on the evolution of ancient Chinese street morphology. The ancient Chinese street form is divided into four stages, namely the Tang and Song Dynasties, the Yuan, Ming and Qing Dynasties, the Late Qing Dynasty, and the founding of New China. The influencing factors of street shape are divided into four categories, namely, the influence of commodity economy, the influence of foreign culture, the influence of building materials, and the influence of traffic. This paper elaborates the influence mechanism of these four factors on the street form in China. The article finally puts forward the development trend of my country’s future street form, and points out that the evolution of my country’s street form will develop in the direction of intelligence, and intelligent transportation, intelligent garbage classification system, etc. will be applied. The number of brick-and-mortar stores in my country’s street layout may decrease.","PeriodicalId":45004,"journal":{"name":"Journal of Computational Methods in Sciences and Engineering","volume":"23 1","pages":"2401-2411"},"PeriodicalIF":0.5,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70041042","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}
