Unfortunately, many algorithms for gene expression analysis require a complete matrix of gene array values as input. Thereore, effective missing value estimation methods are essential to minimize the effect of incomplete data sets on analysis, and to increase the range of data sets to which these algorithms can be applied. In this regard, a new interpolation based imputation method is proposed to predict missing values in microarray gene expression data. The proposed method selects a subset of similar genes and a subset of similar samples with respect to each missing position and then applies interpolation in a novel manner to predict that missing value. The performance of the proposed method is studied based on the normalized root mean square error with existing estimation techniques including K-nearest neighbor (KNN), Sequential K-nearest neighbor (SKNN) and Iterative K-nearest neighbor (IKNN). The effectiveness of the proposed method, along with a comparison with existing methods, is demonstrated on different microarray data sets.","PeriodicalId":274831,"journal":{"name":"2012 International Conference on Communications, Devices and Intelligent Systems (CODIS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126083120","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}

It has potential applications in diverse fields including automatic surveillance of large areas, illegal vehicle movement tracking in remote areas etc. This technique poses many challenges in terms of retaining only the target pixels by identifying and removal of noise pixels efficiently. In the case of detecting stationary targets concealed by foliage, traditional imaging techniques in the visible domain fail and Synthetic Aperture RADAR (SAR) imagery in the UWB-VHF (20-90 MHz) band comes to rescue. However, these foliage penetrating frequencies are also prone to high frequency speckle noise which asks for a robust target detecting technique. In this paper, one such algorithm based on Incoherent Change Detection and adaptive thresholding by Stein's Unbiased Risk Estimate (SURE) is proposed. The images used for testing were a set of 24 CARABAS-II VHF SAR images taken during a flight campaign in Sweden in the year 2002. The code has been written in MATLAB Platform and is able to successfully locate all the regions where the target is present and the False Alarm Rate (FAR) is also minimal. The execution times of the code for various image sets are also very promising and lie in the range 16-26 seconds for all the images chosen.","PeriodicalId":274831,"journal":{"name":"2012 International Conference on Communications, Devices and Intelligent Systems (CODIS)","volume":"19 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130450","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}
