However, a portfolio can help investors achieve a better result with a proper allocation of good quality assets and appropriate weights. In this study, we construct an automatic asset selection and allocation system. We first apply the genetic programing to design new risk factors which can bring abnormal return based on classical factors and then use the classical factors to select stocks. After that, weight of each stock is optimized by NSGA-II with three objective functions: Sharpe ratio, skewness and kurtosis. Our factors generated through by genetic programming successfully capture the abnormal return and NSGA-II helps us maximize Sharpe ratio and minimize drawdown and shortfall. In the last, though we have achieved remarkable cumulative return based on the optimized portfolio, more efforts are needed while applying it to the real market","PeriodicalId":346592,"journal":{"name":"Proceedings of the 2020 The 6th International Conference on E-Business and Applications","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128123907","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":"The Effectiveness of Using mBot to Increase the Interest and Basic Knowledge in Programming and Robotic among Children of Age 13","authors":"Beng Yong Lee, L. H. Liew, Mohd Yazid Bin Mohd Anas Khan, A. Narawi","doi":"10.1145/3387263.3387275","DOIUrl":"https://doi.org/10.1145/3387263.3387275","url":null,"abstract":"The encouragement program of Science, Technology, Engineering and Mathematics (STEM) among students has been the focus of policymakers from different countries including Malaysia since the rapid development of the Internet of things (IoT). The objective of the STEM initiative is to promote interest among students in taking up the related STEM subjects especially the subjects of computer science and electronics engineering. The program also expected to produce students who have knowledge, skills and values in the STEM fields to increase the number of experts in preparing an adequate supply of qualified workers for employment. Many approaches have been applied to increase the interest of students in learning STEM and one of them is using robots. Robots have the edge of becoming the next big thing in traditional curricula. The enjoyment and excitement that bring into the learning experience by using robots are deemed as an instrumental aspect for teaching young children. This paper discussed the effectiveness of using low-cost Arduino based robots to increase the interest of students in learning about electronics and computer programming. A workshop on learning robotic programming was conducted in two selected secondary schools in Sarawak by Universiti Teknologi MARA Sarawak. A total of 93 participants of age 13 years old were taking part in the workshop. The participants were asked to fill in an entrance survey before the workshop and an exit survey after attending the workshop. By analysing both surveys, the increment of interest on STEM among the students is measured. A competition has been organized to test on the robotic programming knowledge and skills of the students. Five out of six groups of the students could use the sensor that they have not been taught before. Two groups can solve the very difficult questions that involve multiple sensors during the competition. This finding indicates that the workshop has successfully promoted the interest of learning robotic programming among the students because the students have self-learned to use the new sensors of the robot.","PeriodicalId":346592,"journal":{"name":"Proceedings of the 2020 The 6th International Conference on E-Business and Applications","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125622075","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 study used a quantitative research methodology to examine the proposed hypotheses. A sample of 530 Mongolian social media community users aged 18 to 50 was collected by online questionnaire. Structural Equation Modeling (SEM) was used as statistical methods to analyze the relationships and mediate effects between variables. The finding showed that internet celebrity endorsement had significant positive influence on Word-of-Mouth, consumer buying behavior and purchase intention. This study will provoke new insights of future researchers and practitioners of beauty product industries, especially in Mongolian market. Moreover, beauty company will have a better understanding of the impacts of internet celebrity endorsement on consumers' purchasing intention and behavior towards foreign beauty products so as to improve their business practices.","PeriodicalId":346592,"journal":{"name":"Proceedings of the 2020 The 6th International Conference on E-Business and Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130512197","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}

An eye tracking experiment consists of displaying different images with human face embedded in different locations (left, center and right) and the eye tracker captured and tracked the child's eye gaze movements, then analyzed to identify where specifically in the stimulus is the child looking at. The finding indicates a significant difference was found between the two groups viewing patterns and behavior when they presented with a scene that have human face. The study also reveals that large percentage of Autistic participants expressed minimum interest and time looking at face area, evident by significant time spent fixations on non-face regions, comparing to the normal developing children. The results can be used to improve the life style of other children who have a risk to develop Autism as well as discover earlier signs of ASD.","PeriodicalId":346592,"journal":{"name":"Proceedings of the 2020 The 6th International Conference on E-Business and Applications","volume":"321 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115750451","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}
