Recent financial forecasting applications using neural networks typically have not taken the predictive uncertainty into consideration. Without proper consideration of predictive uncertainty, such approaches may lead to unintended investment losses. Therefore, consideration of predictive uncertainty in neural network-based financial forecasting should lead to improved investment decision-making. In this study, the effectiveness of uncertainty consideration in neural network-based financial forecasting was verified through a simulated investment portfolio. We show that ensemble and Bayesian neural network models are effective in realizing more stable investment outcomes.","PeriodicalId":136474,"journal":{"name":"2019 8th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114931296","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}

Meanwhile, such fragile connectivity, low security awareness and the lack of knowledge of users can lead IoT devices to be the target of some attackers and then becomes insecurity of things. To solve that problem, in this research, we aim to build an E-learning system which is based on Ontology method to educate users in order to improve their security awareness. Basically, our system mainly consists of three steps. Firstly, we classified, analyzed and characterized the concepts of IoT security domain. Then we built an IoT security Ontology based on the output of classification and analysis. Finally, we developed a java program to implement the function of automatically generate Multiple Choice Questions based on IoT security Ontology descriptions. In this research, we made E-learning materials by extracting and rearranging useful knowledge from on results of classification and analysis. And using a Moodle as e-Learning platform, we upload those learning materials and all the outputs from our system to Moodle and utilized Moodle to create courses and quizzes in order to let user study through our system.","PeriodicalId":136474,"journal":{"name":"2019 8th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127833350","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 realize these, we are designing a data platform that consists of about ten interconnected subsystems. We aim to incorporate next generation repository (NGR) concepts into our platform; the subsystems share features such as persistent identifier (PID) based resource management, a common metadata model, and vocabulary control. Another vital requirement is that all datasets must be machine-readable and translatable. These features are highly important in developing a platform as a research pipeline capable of handling various materials data – from data creation and efficient collection, to advanced data usage, secure storage, and open publishing.","PeriodicalId":136474,"journal":{"name":"2019 8th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121609451","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 the case study, we analyzed defects that required significant correction effort. The defects were ambiguity defects injected by misunderstandings and inconsistencies among stakeholders during interpreting requirements and specifying design documents. The ambiguities of the specifications are found in the definitions of distance, time (time zone), and calculation accuracy. These cause non-conformance in the implementations and errors in the control simulation execution results. Based on the analysis, as a low-effort defect prevention approach, we propose clearly defining the units to avoid such ambiguities and estimated the expected effort reduction by the definitions in the target control simulation software development.","PeriodicalId":136474,"journal":{"name":"2019 8th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116576827","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}

A preliminary study was conducted to examine the effects of levels of prior knowledge (low vs. high) on participants' learning effectiveness and attitude toward the implemented AR-enhanced theme-based contextualized learning. The analysis suggested that prior knowledge affected participants' learning from the experimental AR-enhanced learning. With the advantage in prior knowledge, the high prior knowledge learners outperformed the low prior knowledge learners both in comprehension and application performance and possessed higher degrees of confidence, preferences, deep learning and learning strategy but with lower degrees of anxiety.
