Sung, Divya Suryakumar","doi":"10.1109/IIAI-AAI.2014.105","DOIUrl":"https://doi.org/10.1109/IIAI-AAI.2014.105","url":null,"abstract":"In mining massive datasets, often two of the most important and immediate problems are sampling and feature selection. Proper sampling and feature selection contributes to reducing the size of the dataset while obtaining satisfactory results in model building. Theoretically, therefore, it is interesting to investigate whether a given dataset possesses a critical feature dimension, or the minimum number of features that is required for a given learning machine to achieve \"satisfactory\" performance. (Likewise, the critical sampling size problem concerns whether, for a given dataset, there is a minimum number of data points that must be included in any sample for a learning machine to achieve satisfactory performance.) Here the specific meaning of \"satisfactory\" performance is to be defined by the user. This paper addresses the complexity of both problems in one general theoretical setting and shows that they have the same complexity and are highly intractable. Next, an empirical method is applied in an attempt to find the approximate critical feature dimension of datasets. It is demonstrated that, under generally reasonable assumptions pertaining to feature ranking algorithms, the critical feature dimension are successfully discovered by the empirical method for a number of datasets of various sizes. The results are encouraging in achieving significant feature size reduction and point to a promising way in dealing with big data. The significance of the existence of crucial dimension in datasets is also explained.","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133100446","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}

However, most of the existing Mobile learning systems only allows learners to passively receive knowledge without considering the temporal and spatial information of the learners. The paper proposed a context-aware mobile augmented reality learning platform, called Historical Time Tunnel (HTT), as scaffolding platform for outdoor field learning. The location-based nature of Augmented Reality (AR) technology, AR-based Mobile learning systems could enable learners to acquire the historical interactive knowledge that are related to the specific geographical location. Through such direct interaction with location-based information provided by AR-based M-learning technology, the knowledge acquisition efficiency can be significantly boosted. The designed HTT system not only focuses on student learning management module but also provides teaching material management module for teachers. The conducted experiments on the elementary school student successfully prove that HTT system is an effective scaffolding tool for the novice teachers as well as a helpful assistant to the experienced teachers.","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123535475","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 order to perform large-scale Projection Mapping, multiple projectors are required. In this paper, we propose a new representation technique by various attempts. To determine more impressive visual expression, we have developed Projection Mapping and devised Prodigious Mapping. We have set the projector not to project from many directions, but from one direction. We have been pursuing the possibility that we could use Projection Mapping not only as one of the movie technique but also as a practical approach into a wide range of fields, such as coordination of the shopping mall as regional contribution, transmission of academic contents in the science museum, projection to the historic building to inform the history and culture and so on. We developed the new projection method, \"Gem Mapping\", specializing for indoor settings. In this method, we make objections made with white boards and set them on a wall inside of a building. We create big gems on the wall by projecting video to the objects. Gem Mapping can set inside the building permanently and reduce the costs. We use touch sensor to detect the motions of people and change images to create interactive Projection Mapping. Gem Mapping is a new advertising media to be used in a lot of commercial facilities as digital signage.","PeriodicalId":432222,"journal":{"name":"2014 IIAI 3rd International Conference on Advanced Applied Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121060827","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}
