Capitalizing on this model and novel equation for estimating a student's knowledge level has been also derived. Parameters in derived equation are then optimized by minimizing the root mean square error between classical test results of students and result of estimation model calculated by equation. Knowledge level gain, acquired by using the application is estimated and presented in the function of equation parameters as another performance measure. Sensitivity of obtained performance measures has also been observed. Presented results show the possibility of applying presented method in various game-based learning applications for knowledge level performances determination.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114478765","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}

Train movements are simulated based on timetables. Using the framework a web application is developed. A map service is used for displaying the railway system and the simulation.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117087228","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}

Conventional image compression algorithms are solely tuned for optimal human perception. This paper studies the effect on features used in discriminative cascade classifiers for nighttime pedestrian desection, namely Haar wavelet features, Edge Orientation Histogram features and Standard deviation features. The induced error is modeled and evaluated for these feature classes. By approximating the noise on specific image feature instances, a re-adaption of the decision boundaries is possible. Knowing about the sensitivity of specific feature classes allows selecting a robust set of features prior to classifier training.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127090903","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 of tourism packages, the customer can choose from predefined ones both online or offline, or they can use numerous specialized web pages that can be of lesser or greater complexity. Most of them configure a package from a series of lists which the customer should pick an option from. This can often be rather time-consuming and annoying, especially if the customer has no real knowledge about the options available. Therefore, this paper presents an automated solution for a tourism package configurator, accompanied with a case study.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127548906","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 this type of networked environment the data model can change dynamically over time (concept drift). Identifying when concept drift occurred is a key for several drift handling techniques and important in numerous scenarios. However drift handling approaches exist, no efficient solution for detecting the drift is known in very large scale networks. Here, we propose an approach that can detect the concept drift in large scale and fully distributed networks. In our approach, the learning is performed by applying online learners that take random walks in the network while updating themselves using the samples available at the nodes. The drift detection is based on an adaptive mechanism which uses the historical performances of the models. Through empirical evaluations we demonstrate that our approach handles the drifting concept while additionally detects the occurrence of the concept drift with high accuracy.","PeriodicalId":207630,"journal":{"name":"2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134578573","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}
