We present prototype-based classification schemes, e. g. learning vector quantization, with cost-function-based and geometrically motivated reject options. We evaluate the reject schemes in experiments on artificial and benchmark data sets. We demonstrate that reject options improve the accuracy of the models in most cases, and that the performance of the proposed schemes is comparable to the o...

One of the major shortcomings of modern e-learning schemes is the fact that they significantly lack on user personalization and educational content representation issues. Semior fully automated extraction of user profiles based on users’ usage history records forms a challenging problem, especially when used under the e-learning perspective. In this chapter we present the design and implementat...

the steady growing innovations in the area of information and communication technology have raised new concepts and possibilities in different life aspects. in the field of further education and professional training, electronic learning and web-based education are perhaps the most prominent ones. proponents of this technology claim that e-learning courses are at least as effective as correspon...

rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. among different techniques, rss-based  schemes and in particular oneof its variants which is based on graph-based semi-supervised learning (g-ssl) are widely-used approaches the superiority of this scheme is that it has low setup/training cost and at the same ti...

the successful adoption of e-learning systems is mainly dependent on the learners’ attitude and willingness to use them. this survey was conducted to investigate agricultural extension workers’ attitudes toward using e-learning for on-the-job training in iran and factors which affect it. using the stratified sampling technique a sample of 379 extension workers were selected from six provinces. ...

introduction e-learning is there to enhance knowledge of patients and  can provide an efficient way to enhance personnel-patient interaction and provide patient-specific education. so the aim of this study was to compare the effect of two educational methods, e-learning (multimedia) and painted booklet on primipar women’s knowledge about neonatal care.methods this was a quasi-experimental study...

Introduction: The collaborative learning and interactive electronic-learning (e- learning) is one of the key factors in education system success. This study examined the collaborative e-learning in the framework of constructivism theory. Methods: This is a review article. The databases such as Scientific Information Databases, Magiran, Science Direct, and Google Scholar were reviewed. Also,...

It is a common fact that modern e-learning schemes lack educational content representation and user personalisation. In this framework, automated extraction of user profiles, to be used in an e-learning content offering system, forms an interesting and important problem. In this approach we present the design and implementation of such a profile-based system, by which content is matched to its ...
