Co-training is a well known semi-supervised learning algorithm, in which two classifiers are trained on two different views (feature sets): the initially small training set is iteratively updated with unlabelled samples classified with high confidence by one of the two classifiers., In this paper, we present an iterative self-training semi-supervised SVM algorithm and a corresponding model selection method. This model selection method is based on Fisher ratio and it is suitable when the training data set is small and cross-validation-based model selection method may not work..

In this work, a self-trained NBC4.5 classifier algorithm is presented, which combines the characteristics of Naive Bayes as a base classifier and the speed of C4.5 for final classification. A larger training set decreases the score because it is more difficult for the learning algorithm to learn a model that correctly represents all the training data. However, as we increase the size of the training set, the test score also increases, due to an increase in the model's ability to generalise..

A small variation in data can lead to different decision trees when using C4.5. For a small training set, C4.5 does not work very well. 2.3.3 CART It stands for Classification And Regression Trees.
