Added GaussianNB Classifier : KNN Classifier is sensitive to irrelevant features, we can use Naive Bayes Classifier which doesn't require much training data.
Added SVM Classifiers : As KNN Classifier and DecisionTree Classifier suffer from curse of high dimensionality, SVM classifiers are more effective in high dimensional data and SVM classifiers are relatively memory efficient
