Most detection approaches rely on identifying specific artifacts that can quickly become obsolete due to the fast advance in facial forgery methods. Some facial manipulation detection methods use temporal information to classify the video as real or fake. These methods mainly rely on 3D CNN architectures or two-stream networks using frame and video features. Our method not only considers temporal aspects, but it comes from a different perspective: extracting features that can account for inter-frame changes on a video. Inspired by the concept of ratio images, we extract features based on the ratio between adjacent frames for the face and its background. The experimental evaluation showed better results in intra- and cross-dataset tests on FaceForensics++ (FF++) and CelebDF datasets compared to the state-of-the-art deepfake detection approaches in the assessment with seen and unseen facial manipulation methods, as well as in seen and unseen video settings. In the intra-dataset experiment, the model resulted in an AUC of 100% for both CelebDF and FF++ datasets. In the cross dataset experiment, the model resulted in an AUC of 98% when trained with CelebDF and tested with FF++ and 86% when trained with FF++ and tested with CelebDF.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126276228","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 general, there is some lead-lag effect in the spread of price information due to the limited attention of investors. The industry momentum exploits the lead-lag effect due to information spillover delays within industries. In this study, We test whether industry momentum is stronger when we use information that is not attracting the attention of investors. We first perform industry classification with text mining of Annual Securities Reports describing the business activities of each company listed on the Japanese stock market. Then, we can identify groups of industry peer companies with low investor attention that is likely to cause the lead-lag effect. Such a text-based industry classification based on Annual Securities Reports is less visible to the investors but has an economic link among companies. We confirm that industry momentum base on text-based industry classification is more significant than traditional industry classification in Japanese stock market.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133605124","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}

Recreational rehabilitation is known as an effective way to improve language skills and avoid social isolation. However, in order to effectively implement rehabilitation, it is necessary to solve the issues required of the moderator, specifically, to provide greater care to the participants, to reduce the burden of preparation, and to make it possible for those with limited experience to carry out the program. To solve these issues, the use of communication robots is expected. However, it is difficult to easily introduce such systems in terms of reliability, reproducibility, and automation in nursing and welfare fields where people are unfamiliar with the handling of information devices. Therefore, this study aims to make effective use of robots. First, by analyzing the role of the moderator through interviews with nursing care staff, a role that can be played by a robot was extracted. Next, a method to enable the robot to take on the role of the moderator was studied, and a method was proposed that combines existing technologies that are highly reliable and easy for nursing care staff to handle. Specifically, a system was proposed in which the robot's lines can be edited by the nursing staff using an editable PowerPoint presentation in advance preparation, and the timing of the robot's speech can be controlled remotely with a single click during recreation. A trial rehabilitation experiment using the proposed system showed the possibility of reducing the burden on the moderator while achieving participant communication equivalent to that of a human moderator.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133176050","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}
