Most of the algorithms developed for this purpose, take advantage of single-objective optimization methods which may be ineffective for complex networks. In addition, most of the networks in the real world are weighted, and therefore, this fact must be of special interest in order to achieve more precise communities in partitioning strategies. Accordingly, in this paper, a community detection method for weighted networks is proposed using multi-objective optimization based on genetic algorithm. Performance evaluation based on experiments on real datasets, shows that considering weights of the edges, leads to higher modularity factor.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133086368","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}

Choosing a proper learning sample plays a significant role in runtime and accuracy of the supervised classification algorithms, specially the Ho-Kashyap classification algorithm. This article with combining the methods of Multi Class Instance Selection and Ho-Kashyap, not has only reduced the starting time of algorithm, but has improved the accuracy of this algorithm, using proper parameters. The results of this suggested method, in terms of accuracy and time, are evaluated and simulations have proved that MCIS method can choose the data that have more effectiveness on classification, using proper measures. If Ho-Kashyap algorithm classifies using more important data, it could be to save the time in classification process and even increases the accuracy of classification.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127236346","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}

Since the proposed method imposes considerable area overheads, we cannot apply it to all gates of the circuit to improve the circuit SER. So, at first, we identify the gates which are more sensitive to soft errors using a computational model. Then, we propose a method in order to reduce the SER of the circuit. This method optimizes the circuit SER considering the overheads on circuit area. Experimental results based on simulations performed on ISCAS'85 benchmark circuits show that the method can provide an SER reduction of up to 19% with less than 53% area overhead.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132140064","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 proposed method nodes are prioritized and selected for rotating and replacement based on the sensing overlaps; the node with more overlapping areas, has higher priority. The goal is to enhance coverage ratio with reduction of multimedia node overlap. The prioritizing table is updated after each execution of the algorithm in order to select the best node. The proposed method of prioritizing, rotation, and movement, improve the capability of energy conservation and also coverage ratio in the network.

Since it is important to evaluate the effect of the language model on the system, it is necessary to choose the words in a way that they can represent different levels of difficulty based on the language model. In this paper, we will give a brief introduction to the Persian BCI speller that we are going to develop. Then, we will explain how we select words with three levels of difficulty based on both a character-level and a word-level language model. We consider three levels of difficulty, named Easy, Medium and Hard, for which we have selected 3, 6 and 3 words, respectively. We then make a sentence for each of the words, so that the words are presented within a context. By doing so, the language model can predict the possibility of occurrence for each word. The novelty of this paper is in the fact that so far, there have not been implemented any Persian BCI spellers utilizing a language model as an aid in character recognition using the brain signals.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123965636","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 most cases real workflows deviates from hand-made models and they can be plotted as a graphical diagram. Displaying Graphical diagrams with large amounts of data is difficult; because we are limited to two-dimensional computer screens or papers. In some cases it is essential to transform workflows to reduced ones, especially with reducing visualization complexity. In this paper, reduction of workflows is investigated in both structure and semantic aspects. This paper also introduces commonplace methods of reducing complexity of workflow visualizations.

M-commerce was originally coined in 1997 by Kevin Duffey at the launch of the Global Mobile Commerce Forum to mean “delivery of electronic commerce capabilities directly into the customer's hand, anywhere, via wireless technology”. This portable form of commerce is of so much benefit for the stakeholders including the organizations and end-users. However, it has some challenges that need to be mitigated or totally addressed if possible. Cloud computing, specifically in its mobile form, is capable of presenting some solutions for the existent challenges. In this research, the most common challenges and weak areas of M-commerce is considered, and their corresponding cloud solutions are presented. Additionally, based on the available M-commerce reference model, a new layered structure including the cloud services is provided, and a new cloud-based M-commerce architecture is suggested accordingly.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129707349","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}
