Because the traditional EM algorithm has the disadvantage that the algorithm has the sensitivity of initial value and converge to local optimal point easily. This paper proposed a new improved EM algorithm based on the q-DAEM. The improved algorithm applies the EM algorithm to generate a constrained matrix, then combine the constrained matrix with the q-DAEM algorithm to reduce the search range, so that a better Gaussian mixture model can be derived from this algorithm. The algorithm was applied to the Moore datasets for evaluation, the experimental results show that this improved algorithm which applied to network traffic classification can lead to a higher precision and overall accuracy.","PeriodicalId":350687,"journal":{"name":"2016 8th International Conference on Knowledge and Smart Technology (KST)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122043837","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 gaze-cueing effect, a phenomenon by which the visual system directs attention to the spatial location indicated by another's gaze, was used to measure these types of attentional orientation. In Experiment 1, we observed a positive correlation between general trust and the gaze-cueing effect with different cue-target SOAs; general trust was reflected in both voluntary and involuntary attentional orientation triggered by gaze direction. In Experiment 2, the cueing stimulus was not social, and a positive correlation was only observed for voluntary attentional orientation. These results suggest that general trust might be reflected in relatively early cognitive processes regardless of whether it is triggered voluntarily or involuntarily by another's gaze direction. Furthermore, general trust might be differentially related to attentional orientation based on whether or not it is triggered socially.","PeriodicalId":350687,"journal":{"name":"2016 8th International Conference on Knowledge and Smart Technology (KST)","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121409717","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}

Results from the approach of the SISO Volterra show capability for successful modeling of the ultraharmonic. We have investigated the accuracy of predicting the ultrasound echo signal under different noise levels. In addition, the SISO Volterra can be still modeled subharmonic frequency component.

Since an interval representation consists of one lower bound and one upper bound, they need more space usage and more computational time comparing to a traditional number representation.

In this work, we propose a modified version of FIRS with respect to the negative binary base. The result shows that space can be reduced up to fifty percent. We also propose addition and subtraction algorithms together with a digit-set conversion using an on-the-fly conversion for this novel interval representation system.","PeriodicalId":350687,"journal":{"name":"2016 8th International Conference on Knowledge and Smart Technology (KST)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126602757","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 efficiency of seven models created from data mining with classification technique by using seven algorithms that are Artificial Neural Network, K-Nearest Neighbor, Naive Bayes, Bayesian Belief Network, JRIP, ID3 and C4.5 is compared and it was found that the models created from C4.5 has the best efficiency. The accuracy of the model created from C4.5 is about 74.8945% and the accuracy tests show that this model is reliable. Therefore this model is selected to group learners with STAD technique for cooperative learning through web. The result also shows that ID3 is inappropriate to predict learners' performance. The data mining model created from C4.5 shows that math's GPA has the most influential for academic performance in computer programming subject. The model for the cooperative learning model via web using C4.5 to group learners consists of 5 components that are data management module, prediction and grouping module, learning resources, cooperative community and quiz module. The results also show that in the case of using the selected model to group learners and in the case of grouping learners by the lecturers, the learning progressive-score in the first case is higher.","PeriodicalId":350687,"journal":{"name":"2016 8th International Conference on Knowledge and Smart Technology (KST)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125106887","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 amount of force acting in the brain is related to the emotional impacts in the mind as an excitement or an addiction to the game. Measures of the acceleration of the game information have been proposed in earlier studies. A conceptual idea for a possible measure of the mass component of the force of the game information in the brain is proposed. This measure of the mass is based on the neuronal activity in the brain.

These features motivate the researchers to propose power-aware communication protocols. Clustering is used to help for this purpose. It is used to organize the massive number of deployed sensors in the network to minimize energy consumption. Different categories of clustering techniques were proposed. One of these categories is density-based clustering which mainly depends on measuring the density around nodes before grouping them into clusters. This paper proposes an Energy-Efficient Density-based clustering technique which aims to balance the energy consumption among all clusters. This is done by the adaptation of the transmission range of cluster heads to use a suitable value according to the density around it. Simulation results for the proposed technique shows its effectiveness as it achieves less power consumption and more network lifetime when compared with other density-based clustering techniques.","PeriodicalId":350687,"journal":{"name":"2016 8th International Conference on Knowledge and Smart Technology (KST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130368445","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 many users can be involved willingly and monitored in a more or less intrusive manner with data collected in their homes. This data can be collected from mobile and wearable devices (such as smart phone and smart watch), from sensors disseminated in the home (such as motion detectors and contact switches) and from self-reported information systems (using paper based or web-based ecological momentary assessment techniques). This data can then be useful to characterize the activity, the health and the well-being of the involved person. Enabling people suffering (such as elderly people, people with physical disabilities and people with mental-health condition) to stay in their home as long as possible in good condition is an important challenge for many countries. Firstly, most of people would rather to continue to live in their own home rather than move to a nursing-home or an hospital, secondly the solutions enabling staying at home are also usually cheaper for the society. As a consequence Smart Home and Ambient Assisted Living (SHAAL) systems gain more and more attention. SHAAL systems use information and communication technologies in a person's daily living environment to enable them to stay active longer, remain socially connected and live independently. SHAAL's research covers a wide range of topics. This talk will review the main aspects of SHAAL systems from the data mining point of view. Several case studies will be illustrated. In particular it will emphasize the key role of activity learning and behavior understanding.","PeriodicalId":350687,"journal":{"name":"2016 8th International Conference on Knowledge and Smart Technology (KST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114440607","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}
