Diabetes mellitus is one of the major healthchallenges all over the world. The prevalence of diabetes is increasing at afast pace. To this end, application of machine learning and data mining methodsin biosciences is presently, more than ever before, vital and indispensable inefforts to transform intelligently all available information into valuableknowledge. Prevention and prediction of diabetes mellitus is increasinglygaining interest in diabetes mellitus.

This study follows bagging techniquesusing decision tree as a base learner to classify patients with diabetes mellitususing diabetes risk factors. The experimental research shows bagging techniqueis better method to classify the risk factor of diabetes. Keywords—Machinelearning, Bagging 1.       INTRODUCTION             The remarkable advances inbiotechnology and health sciences have led to a significant production of data,such as high throughput genetic data and clinical information, generated fromlarge Electronic Health Records (EHRs).To this end, application of machinelearning and data mining methods in biosciences is presently, more than everbefore, vital and indispensable in efforts to transform intelligently allavailable information into valuable knowledge.

Diabetes mellitus (DM) isdefined as a group of metabolic disorders exerting significant pressure onhuman health worldwide Extensive research in all aspects of diabetes has led tothe generation of huge amounts of data. The aim of the present study is toconduct a systematic review of the applications of machine learning, datamining techniques and tools in the field of diabetes research with respect toPrediction and Diagnosis. The prediction system includes: §  Analysisof patients metabolism§  Predictingthe level of symptoms§  Riskanalysis of diabetes§  Predictionof diabetes   The diabetesmellitus is one of the dramatically increasing metabolic diseases.The analyzingthe risk factor is challenging one.But with the machinelearning approaches we can find a strong solution to this issue. Here we havedeveloped a system using data mining techniques to predict the whether thepatient is insighted with diabetes or not.

Meanwhile to put forward of riskanalysis in diabetes mellitus. The research is mainly focused on developing asystem over the classification methods namely bagging, Decision treealgorithms. All these algorithms helps to find more accurate values forprediction.  we had collected the dataset of diabetesmellitus patient which consists of following attributes namely number ofpregnant, level of glucose in blood, production of insulin by pancreas,similarly nine attributes.

Thisclassification is done across three different ordinal adults groups in CanadianPrimary Care Sentinel Surveillance network. The title applications in theselected articles project the usefulness of extracting valuable knowledgeleading to new hypotheses targeting deeper understanding and furtherinvestigation in DM.2. EXPERIMENTALMETHODOLOGY      2.

1Bagging              Baggingis actually derived for bootstrap aggregating one of the simple and powerful ensemblemethod to improve the accuracy of learning algorithms. In bagging algorithm thedataset is distributed to various bootstrap replicates. The values getsreplicated  independently from originaldataset. This process gets continued running the weak learner on variousboostrap. From the weak learner the classifiers at each iteration it iscombined to strong composite classifier in order to get strong accuracy.
