Traditionally, these algorithms make trees recursively and at each step, they inspect data to induce the part of the tree. However decision trees are famous for their instability and high variance in error. In this paper a solution which adds error correction rule to a traditional decision tree algorithm is examined. In fact an algorithm which we call it, ECD3 is introduced. Algorithm of ECD3 inspects data sequentially in an iterative manner and updates tree only when it finds an erroneous observation. This method was first proposed by Dr. Utgoff but not implemented. In this paper, the method is developed and several experiments are performed to evaluate the method. We found that in most cases, performance of ECD3 is comparable to its predecessors. However ECD3 has some benefits over them. First, sizes of its trees are significantly smaller. Second, on average, variance of error in ECD3 is lower. Furthermore, ECD3 automatically chooses part of data for induction of the tree and sets aside others. This capability can be exploited for prototype selection in various learning algorithms. To explain these observations, we use inductive bias and margin definitions in our theories. We introduce a new definition of margin in ordinary decision trees based on shape, size and splitting criteria in trees. We show that how ECD3 expands the margins and enhances precision over test data.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"18 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":"127454047","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}

Some of important concerns for supporting adaptation in service-based applications are related to implementation level (low level) of adaptation. At implementation level of adaptation, there are two open important problems. First, it is necessary to realize adaptation mechanisms by their strategies, tactics and techniques. Second, these mechanisms must be integrated into running process via a holistic method. Consequently in this paper, a comprehensive adaptation mechanisms' schema offered which presents a universal set of adaptation tactics for realizing adaptation strategies and also, a suitable approach proposed that deploys these strategies and tactics. In this approach, reconfiguration of process is optimized or achieved at run-time based on specific environment and available services. In order to assess proposed approach, the case study of urban crisis management is implemented. In this case study, a subset of adaptation mechanisms is deployed regarding proposed approach. The results of the evaluation show that adaptation mechanisms have been deployed successfully. Also, quality attributes of adaptive process are adjusted to encounter unexpected events. In addition, strategies' overhead is computed.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"48 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":"121321082","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}

According to massive amounts of data, congestion control is essential for quality preservation of the video data. Quality of video data depends on low latency and high reliability. In this paper, an approach for congestion control is proposed. In the proposed scheme, the network area is divided into zones, and a mobile local sink is utilized in each zone which will lead to the network minimum latency. Also, to raise the quality of video data, the proposed method considers different levels of the buffer queue for each data type (video, sound, and scalar). Moreover, to improve the video data quality at each mobile sink, a unique identifier for each event is considered. The mobile sink in each zone, receives the event packets in the separate queue of the related identifier. Simulation results shows that the proposed method results in saving of more amount of energy and thus increasing the network lifetime, while the packet loss reaches to zero.","PeriodicalId":205496,"journal":{"name":"2016 Eighth International Conference on Information and Knowledge Technology (IKT)","volume":"33 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":"128138469","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}
