In order to reduce the workload for origin server and to increase the reliability of video delivered, a dedicated content delivery network (CDN) is needed. CDN, these days, could provide a reliable network to deliver videos, often representing the origin server, to serve clients' request. Request routing peering system usually are able to route clients' request to an “appropriate” server, named as surrogate server, within a CDN. However, due to the cost involved for setting up new surrogate server, as the number of client increases, herewith, peering of CDN is being introduced to increase the capacity and the coverage, i.e. collaborating with several CDN. Our idea is to re-route a request to other CDNs when the request for a video in a particular CDN could not be found. In this paper, we also analyze the performance of such request routing system which is based on two policies, namely; (1) closest surrogate server, and (2) workload balance, in order to re-route requests to a “suitable” surrogate server, thus, providing a stably high throughput with low error rate when delivering videos to clients. The simulation results show that closest surrogate server policy performed better during non-peak hour while workload balance policy performed better during peak hour.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"460 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116777165","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 addition, labeled data is often difficult and expensive to obtain sufficiently large amount of data. So, learning features from unlabeled data is proposed since unlabeled data is much easier to obtain than the labeled data. In this work, a highlevel feature representation is created by a sparse autoencoder with convolutional extraction. A sparse autoencoder is an unsupervised feedforward neural network that is trained to predict the input itself and has been widely used for learning good feature representation. A major advantage of this feature extraction approach not only provides good feature representation for higherlevel tasks but also can scale up to large images. However, there are several parameters that require careful selection to obtain high performance. The main objective in this work is to present a detailed analysis on the effect of receptive field resolution in handwritten classification based on MNIST database. In the experiment, the results show that receptive field resolution is one of the critical parameters to achieve state-of-the-art performance.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114907588","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}

This paper has three main contributions. The first contribution is an experimental comprehensive study of an optimal interpolation technique selection and an optimal number of gradient directions in single image super resolve reconstruction based on the high-frequency image prediction under a noiseless environment. Moreover, the study of optimal M0 parameter selection is computationally explored for this environment. The second contribution is a study of an experimental performance of the reconstruction under several blurred environments at different blurred variance. Moreover, the study of optimal M0 parameter selection is computationally analyzed for this blurred environment. Finally, the last contribution is a study of an experimental performance of the reconstruction under several noisy environments at different noise power levels and the study of the optimal M0 parameter selection is analyzed.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116006759","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}
