A Machine Learning Model for Product Fraud Detection Based On SVM 基于SVM的产品欺诈检测机器学习模型
Yiyang Dong, Keyu Xie, Zhan Bohan, Lan-Hui Lin
With the rise of IoT technology, more and more companies use this technology for daily work production. This technology will generate large amounts of data during the application process. If data can be used wisely, it will help companies make better decisions. It is very meaningful to establish a model based on supply chain data to determine whether there is fraud in the product transaction process. It can help merchants in the supply chain avoid fraud, default and credit risk, and improve market order. In this paper, we propose a fraud prediction model based on the SVM classification model. Due to the large amount of data provided by the materials, we first perform feature engineering on the data to obtain processed data that can be used for modeling, and then use the SVM classification model algorithm for data classification and regression. Experiments show that the accuracy of the SVM classification model is 98.61. Compared with logistic regression model and naive Bayes model, it has better data classification and regression capabilities.
随着物联网技术的兴起,越来越多的公司将这项技术用于日常工作生产。该技术将在应用过程中产生大量的数据。如果数据可以被明智地使用,它将帮助公司做出更好的决策。建立基于供应链数据的模型来判断产品交易过程中是否存在欺诈行为是非常有意义的。它可以帮助供应链上的商家避免欺诈、违约和信用风险,改善市场秩序。本文提出了一种基于SVM分类模型的欺诈预测模型。由于材料提供的数据量较大,我们首先对数据进行特征工程处理,得到可以用于建模的处理数据,然后使用SVM分类模型算法对数据进行分类和回归。实验表明,该SVM分类模型的准确率为98.61。与逻辑回归模型和朴素贝叶斯模型相比,具有更好的数据分类和回归能力。

A cross-section research was conducted on 1969 participants in February 2020 who were randomly selected from public in China. This study evaluated the reliability and validity of revised scale-the Coping Strategies Scale after COVID-19 (CSSC) by using the sample of 420 Chinese from the research. The purpose of the questionnaire revision was to measure people's coping strategies under the threat of COVID-19. Exploratory factor analyses were performed on 200 participants, and confirmatory factor analysis were on 220 participants. SPSS version 18.0 and AMOS 22.0 were used to analyze the data. Regarding the reliability of the scale, internal consistency revealed acceptable coefficient. The T -test was also used to examine the discrimination of the items. The exploratory factor analysis revealed that the scale was suitable for the application of factor analysis. Confirmatory factor analysis via Amos 22.0 was distinguished three dimensions for CSSC: distract, maintain, and escape (GFI=.96; AGFI=.93; RMR=.07; TLI=.95; NFI=.90; RMSEA=.05). The Cronbach's coefficient of the total scale was.79. The revised CSSC shows appropriate structural validity and relatively appropriate reliability, which can be used to measure coping strategies.

Liu Rui, Yu Wang, Xia Tong
Under the background of rapid economic growth in my country, the demand for social development has shifted from “demographic dividend” to “health dividend”. The development of urbanization has formed a special vulnerable group of “left-behind children”. The problems of left-behind children's physical weakness and mental illness will directly affect the quality of my country's health dividend in the future. As a scientific and effective means, sports participation can enhance the collective sense of honor of its members and enhance the sense of psychological belonging. Methods: This article uses the “School Belonging Scale” compiled by Goodenow and the “Positive/Negative Affective Scale for Junior High School Students” compiled by Goodenow to conduct a random sample survey of 176 left-behind children and 182 non-left-behind children, and use analyze the result by the SPSS. Results: 1. LS group and FLS group had statistical significance in sense of belonging and emotion (P<0.01). 2. LS group and FLS group have statistical significance in the sense of belonging and emotion in participating in sports activities (P<0.01). 3. The FLS group has statistical significance in the sense of belonging and emotion in participating in sports activities and not participating in sports activities (P<0.05). Conclusion: Sports participation can enhance the sense of collective belonging of left-behind children and promote the overall physical and mental health of rural left-behind children.

Research on the Teaching Mode of Educational Psychology in Universities based on The Internet 基于互联网的高校教育心理学教学模式研究
Huang Rongfeng, Gao Chaomin
Through the analysis of necessity of teaching mode reform based on the web-based course of education psychology in Universities, we have proposed a hybrid of teaching mode. Then students conducted a questionnaire survey on the pattern recognition, fitness, educational degree, degree of satisfaction of college. SPSS21.0 was used to analyze the survey results, and it was found that the majority of college students had low recognition, high fitness, a high degree of financial aid, and a low degree of satisfaction for the blended teaching mode of Educational Psychology. Given the reason for low satisfaction, this paper further discusses the shortcomings of the hybrid teaching mode and finds that most of the students' dissatisfaction with this teaching mode is mainly focused on “teaching pertinence”.
通过对高校《教育心理学》网络课程教学模式改革必要性的分析,提出了一种混合式教学模式。然后对大学生进行模式识别、适合度、受教育程度、大学满意度的问卷调查。运用SPSS21.0对调查结果进行分析,发现大部分大学生对《教育心理学》混合式教学模式的认知度低、适应度高、资助度高、满意度低。针对满意度低的原因,本文进一步探讨了混合式教学模式的不足,发现学生对混合式教学模式的不满主要集中在“教学针对性”上。
