This robust performance that incorporates the simplicity of ESN implementation has led to wide adoption in the machine-learning community. ESN's simplicity stems from the weights of the recurrent nodes being assigned randomly, known as the reservoir, and weights are only learnt in the output layer using a linear read-out function. In this paper, we present a novel approach that combines ESN with support vector machines (SVMs) for time series classification by replacing the linear read-out function in the output layer with SVMs with the radial basis function kernel. The proposed model has been evaluated with an Arabic digits speech recognition task. The well-known Spoken Arabic Digits Dataset, which contains 8800 instances of Arabic digits 0-9 spoken by 88 different speakers (44 males and 44 females) was used to develop and validate the suggested approach. The result of our system can be compared to the state-of-the-art models introduced by Hammami et al. (2011) and P. R. Cavalin et al. (2012) , which are the best reported results found in the literature that used the same dataset. The result shows that ESN and ESNSVMs can both provide superior performance at a 96.91% and 97.45% recognition accuracy, respectively, compared with 95.99% and 94.04% for other models. The result also shows that when using a smaller reservoir size significant differences exist in the performance of ESN and ESNSVMs, as the latter approach achieves higher accuracy by more than 15% in extreme cases.","PeriodicalId":438270,"journal":{"name":"2013 9th International Conference on Innovations in Information Technology (IIT)","volume":"371 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122779671","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}

Bensefia.","doi":"10.1109/INNOVATIONS.2013.6544413","DOIUrl":"https://doi.org/10.1109/INNOVATIONS.2013.6544413","url":null,"abstract":"Modern Collaborative Virtual Environments (CVEs) are no longer developed as a one-piece to support specific applications such as online games, Virtual shopping, and E-health. In the traditional way, any modifications in VE applications require a service interruption in order to change both programming code and the supporting structure. As a consequence the ability to build and/or extend 3D VEs during the runtime becomes tedious task and requires long development time with advanced programming knowledge. Nowadays, it is important to offer an easy and rapid way for users and game developers to build and/or to extend CVE applications during the runtime without having the option to interrupt the system. In this paper, we propose a novel dynamic approach based on event atomic actions management, thanks to the state machine. We employ two different high-level scripting abstractions called class modeling and instance modeling. Class modeling controls what seems to be the simulation scenario, while, instance modeling controls objects and avatars behaviors in the virtual environment. Both class and instance modeling are implemented as a scripting plug-in and mastered respectively by atomic simulation and atomic behavior concepts. The atomic behavior concept is not only limited to object behaviors, it also handles the avatar facial animation parameters as defined in MPEG-4 SNHC standard. We evaluate the benefits of our proposed solution by describing a complex firefighter's game scenario. Through this scenario we explore the interaction between class and instance script modeling as well as the implication of atomic concepts on making code writing, when a VE application modification is required.","PeriodicalId":438270,"journal":{"name":"2013 9th International Conference on Innovations in Information Technology (IIT)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114729818","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}
