In most real-world classification applications, well labeled data is expensive or impossible to obtain. We can often label a small subset of data as belonging to the class of interest. It is frequently impractical to manually label all data we are not interested in. We are left with a small set of positive labeled items of interest and a large set of unknown and unlabeled data. Learning a model for this is the PU learning problem.In this paper, we explore several applications for PU learning including examples in biological/medical, business, security, and signal processing. We then survey the literature for new and existing solutions to the PU learning problem.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132215051","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}

Nowadays, it is crucial for tourism stakeholders to be able to forecast several tourism indicators in order to take appropriate and most profitable decisions. The traditional forecasting models used in tourism are time-series and econometric. In this paper, we propose a methodology which utilizes a data mining technique based on Decision Trees with the aim of providing forecasts for tourism demand taking into account the contribution of explanatory variables. The proposed approach is based on Apache Spark, a robust analytics engine, along with an integrated machine learning library for predicting tourism demand in Greece. The dataset was constructed from publicly available sources and the forecasted (target) variable is the tourist arrivals in Greece for date range 2006 to 2015.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131244220","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}

Multiple and replicated random walker mechanisms, which serve as alternative approaches with the ultimate goal of accelerating the coverage of the network, are considered as well. The performance of these mechanisms is experimentally evaluated and compared to past theoretical findings, in a lowcost wireless network deployed on the buildings of a University campus.

Their advent has motivated many research efforts in data management. 3DXPoint, a new non-volatile memory with even better specifications, is a breakthrough for storage systems; featuring low latency and high IOPS, 3DXPoint can create new lines of research. Towards this direction, hybrid storage systems combining, both flash and 3DXPoint, seem to be an adequate roadmap, since the cost of 3DXPoint remains high. In this paper, we study the performance of R-tree on both flash and 3DXPoint SSDs through careful experimentation. We also examine a simple yet illuminating approach to develop a hybrid index. The conducted experiments on one real and two synthetic datasets show that spatial indexes can achieve significant performance gains by exploiting 3DXPoint technology. To the best of our knowledge this is the first research effort that considers a hybrid flash/3DXPoint storage for R-tree.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131650542","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}

The average aggregation method for weighted interconnections among concepts is the most used method in FCM modeling. The aim of this research work is to (i) propose an alternative aggregation method based on learning OWA operators in aggregating FCM weights, assigned by many experts and/or stakeholders and (ii) to estimate and rank the experts’ credibility using a distance-based method. The applicability and usefulness of the proposed methodology in modeling and decision-making is demonstrated using poverty eradication strategies under DAY-NRLM (Deendayal Antyodaya Yojana-National Rural Livelihoods Mission) of India. The results produced by the proposed learning OWA operators are compared with the known average aggregation method of FCMs. These results imply that the proposed alternative FCM aggregation approach is really challenging when a large number of experts and stakeholders are engaged to design the overall FCM model.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131673903","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}

Their growing popularity has resulted in a large amount of data being available for learning analytics purposes. A major problem of MOOCs is the overwhelming number of posts in their discussion forums. The forum is a key part of the learning process within a MOOC, so this information overload affects negatively the participants’ learning experience. Automatic classification of the posts can help searching of relevant information for both the learners and teaching assistants. In this study, we address this problem by building two multiclass classification models, using natural language processing techniques, that classify the posts according to a three-category coding scheme. Each model was created with data derived from a MOOC of different subject matter. The main goal was to evaluate each model’s accuracy along with its generalizability to courses of different subject matter. This study contributes to the line of research for automatic classification of forum discussions, ultimately aiming at the development of tools that may assist participants while searching in the forum. Furthermore it provides insights on the main issues that inhibit generalization of classifiers created for a specific subject matter and investigate how their linguistic features relate to this inhibition.","PeriodicalId":371385,"journal":{"name":"2019 10th International Conference on Information, Intelligence, Systems and Applications (IISA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132749962","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}
