Biomarker discovery can be modelled as a feature selection problem that aims to find the most discriminating features (genes) for accurate disease classification e.g. healthy vs. diseased samples. Typical feature selection algorithms identify individual genes, and the disease discrimination power of each gene is considered separately. In this paper, we propose a gene selection method incorporating prior biological knowledge about gene pathways to find a group(s) of strongly correlated genes to accurately discriminate complex as well as simple diseases. The proposed method involves a ranking process to identify the most relevant biological pathways in a microarray dataset. A specified number of differentially- expressed genes from relevant pathways is then selected for accurate disease classification. The advantage of this method is that it searches for a group of strongly correlated genes rather than individual genes. We argue that selecting a group of informative and correlated genes from disease-associated pathways is particularly relevant to the disease type or grade. To evaluate the performance of our method, we compare it to five well-known feature selection and ranking methods using two classifiers: K-Nearest Neighbour (KNN) and Support Vector Machine (SVM). Using publicly-available microarray datasets, we found that our algorithm outperforms other methods in terms of disease classification accuracy. Moreover, we were able to reduce the number of genes required to accurately discriminate disease states.","PeriodicalId":158246,"journal":{"name":"International Conference on Information Society (i-Society 2011)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121877275","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}

Many schemes have emerged to enhance the performance of face recognition to deal with poor quality facial images. It has been shown that reporting average accuracy, to cover a wide range of image quality, does not reflect the system's for any specific quality levels. This raises the need to evaluate biometric system's performance at each quality level separately. Challenging face databases have been recorded with varied face image qualities. Unfortunately, the performance of face recognition schemes under different quality conditions, reported in the literature, are evaluated under hidden assumption which cannot be achieved in real-life applications. In fact, this problem could be a source of attack that interferes with the verification through manipulating the recording condition. In order to remedy this problem, two requirements are to be imposed: 1) the matching criteria should be based an Adaptive Quality-Based Threshold (AQBT) and 2) at the verification stage the quality level of an input face image should be determined and classified into one of a non-overlapping predefined quality levels. We illustrate our idea by experiments conducted on the extended Yale B face benchmark dataset. Our experimental results indicate that if AQBT is not adopted, false rejection rates becomes very high (always reject) when using low quality face images.","PeriodicalId":158246,"journal":{"name":"International Conference on Information Society (i-Society 2011)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114022084","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}
