Score level fusion is applied on scores of features extracted from FKPs. An improved identification rate is achieved after fusion as compared to that from the individual knuckle print. There has also been a little effort on study of feature selection. The entropy measures are employed for the feature selection. The experimental results also demonstrate the superiority of the DAISY descriptor over other features in terms of the time and accuracy.","PeriodicalId":370150,"journal":{"name":"2012 12th International Conference on Intelligent Systems Design and Applications (ISDA)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130163504","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}

For the discovery of suitable data sources, keyword based search in the catalogue becomes inaccurate. The main reason behind this is the existing semantic heterogeneity in the database schema, deployed by different service providers. It necessitates the semantic management of the spatial catalogues. This paper presents an ontology based approach which is useful to create and manage catalogues semantically, hence resolving the semantic heterogeneity between geospatial repositories and incompatibility with spatial queries. Further, there is no standard available for semantic searching of the spatial catalogue till date. It will enhance the data extraction process by providing semantic meaning to the spatial catalogue.","PeriodicalId":370150,"journal":{"name":"2012 12th International Conference on Intelligent Systems Design and Applications (ISDA)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133984793","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}

They can be classified as `Nyquist rate converters' and `Over sampled converters'. Former operates at a sampling rate of twice the input signal frequency. They do not make use of the advantages of exceptional high speeds achieved in the current VLSI technology. Also the limitations in matching accuracy of the analog circuits needed in this type, limits their accuracy to an effective number of bits (ENOB) of 12 to 14 bits for various implementations. Over sampling data converters uses sampling rate much higher than Nyquist rate, typically higher by a factor between 8 and 512 or higher. They can achieve over 20 ENOB resolution at reasonably high conversion speeds. The engine behind this over sampling converter is a delta-sigma modulator. The main advantage of delta sigma modulator is that they offer a very good separation of input signal from the quantisation noise due to the over sampling process and noise shaping. The Signal to noise ratio (SNR) for a Nyquist rate converter depends on the number of bits of the converter. In this type SNR can be increased by approximately 6dB per bit. In over sampling converters the SNR depends on the depth of oversampling also, which is specified as `Oversampling ratio' (OSR). Theoretically, for each doubling in sampling rate SNR can be be improved by a factor of 3dB, which corresponds to a half bit increment in Nyquist rate converters. Thus without increasing chip area SNR is increased. In this paper a 10 bit delta sigma DAC is implemented and SNR was measured with various sinusoids at different over sampling ratios. To reduce the number of transistors in the implementation, Minimal energy dual bit adder (MEDB adder) is used.","PeriodicalId":370150,"journal":{"name":"2012 12th International Conference on Intelligent Systems Design and Applications (ISDA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128865183","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}

Larger network traffic and more complex applications make it difficult for the original SNMP-based network management software to meet demands of analyzing users and protocols; widespread utility of dynamic ports greatly reduces the accuracy of distinguishing application layer protocols based on tranditional static ports. Since raw NetFlow is enormous, unfit for long-term storage and low in query efficiency, multiple time granularity aggregation schemes are designed. This paper describes characteristics of both real-time and history traffic from five aspects, thus providing a clearer view of network operating conditions. Besides, as the indicator of users' web access behavior, web sites and URLs are analyzed.","PeriodicalId":370150,"journal":{"name":"2012 12th International Conference on Intelligent Systems Design and Applications (ISDA)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133720839","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 this paper, we discuss some ways to give weights on features in the framework of naïve Bayes classifier, that is, under independent assumption of features. Because no order exists in a categorical feature, we consider a histogram over possible values (bins) in the feature. Taking into the difference of number of samples falling in each bin, we propose two kinds of weights: 1) one is derived from the probability that the majority class takes the majority even in samples, and 2) another reflects the expected conditional entropy. With the latter entropy weight, it will be shown that more discriminative features gain higher weights and non-discriminative feature diminishes as the number of samples goes infinity. We reveal the properties of these two kinds of weights through artificial data and some real-life data.","PeriodicalId":370150,"journal":{"name":"2012 12th International Conference on Intelligent Systems Design and Applications (ISDA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352359","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 method is divided into three stages: image processing, feature extraction and image classification. In the first stage we have used two image processing techniques in order to enhance their features. Then, the second stage reduces the dimensionality of the images and finds features using the statistical method of principal component analysis. Finally, in the third stage the images are classified using machine learning algorithms, particularly, the naive Bayes classifier, neural networks, k-nearest neighbors and support vector machines. In our experimental study we classify two types of retinopathy: non-proliferative and proliferative.
