Abstract: In todays modern world tremendous increase in computer usage newlinedemands storage and retrieval of large amount of data from heterogeneous newlinesources Various data mining techniques are used to discover knowledge from newlinelarge datasets In such datasets incomplete data is a very common problem newlinefaced by analysts Analysis made from such incomplete data may not be newlinealways accurate and lead to misleading decisions Hence some efficient newlinestatistical techniques need to be applied to fill the missing values newlineNumerous techniques have been proposed by researchers to handle newlinethis issue Some simple methods like substituting zero random values default newlinevalues and mean mode values for missing values are commonly followed newlineThey are very simple to use but they assume that all missing values exhibits newlinethe same behavior and replace all their positions with a single value Hence newlinethey are generally not recommended by researchers newlineSome statistical techniques like Knearest neighbor classification newlineKmeans clustering Multiple Imputation Maximum likelihood approaches newlinePrincipal Component Analysis Genetic Algorithms Neural networks newlineBayesian techniques and Kernel estimator are used But application of these newlinetechniques demands more statistical knowledge from the user Also all the newlinetechniques cannot be applied in all scenarios Depending upon the nature of newlinemissingness and type of the attribute technique needed also may vary A newlinegreat challenge faced by analysts and researchers is to search appropriate newlinetechnique suitable for their problem Simple methods are not efficient and newlineefficient methods are not simple enough for all users to understand This newlinesituation was the motivating factor behind this research to develop a novel newlinemethod that can be applied for all kinds of missing mechanisms and newlineattributes newlineThis research proposes a new approach called Bayesian Genetic newlineAlgorithm BAGEL which combines the features of Bayesian principles and newlineGenetic Algorithms to handle missing data problem newline
