analyzing the dataset in [1]. Tanagra tool is used to classify the
data and the data is evaluated using 10-fold cross validation and
the results are compared. Tanagra is a data mining suite build
around graphical user interface algorithms. The main purpose of
Tanagra project is to give researchers and students an easy-to-use
data mining software, and allowing to analyze either real or
synthetic data. Tanagra is powerful system that contains
clustering, supervised learning, meta supervised learning, feature
selection, data visualization supervised learning assessment,
statistics, feature selection and construction algorithms. Decision
Tree is a popular classifier which is simple and easy to
implement. It requires no domain knowledge or parameter setting
and can handle high dimensional data. The results obtained from
Decision Trees are easier to read and interpret. The drill through
feature to access detailed patients‟ profiles is only available in
Decision Trees. Naïve Bayes is a statistical classifier which
assumes no dependency between attributes. It attempts to
maximize the posterior probability in determining the class. The
advantage of using naive bayes is that one can work with the naive
Bayes model without using any Bayesian methods. Naive Bayes
classifiers have works well in many complex real-world situations.
The k-nearest neighbor„s algorithm (k-NN) is a method for
classifying objects based on closest training data in the feature
space. k-NN is a type of instance-based learning. The k-nearest
neighbor algorithm is amongst the simplest of all machine learning
algorithms. But the accuracy of the k-NN algorithm can be
severely degraded by the presence of noisy or irrelevant features,
or if the feature scales are not consistent with their importance.
The experiment is performed using training data set consists of
3000 instances with 14 different attributes. The dataset is divided
into two parts that is 70% of the data are used for training and
30% are used for testing. Based on the experimental results shown
in Table 1, it is clear that the classification accuracy of Naive
Bayes algorithm is better compared to other algorithms.
