In the describe survey CART, ID3 and decision table have been used to predict attributes such as age, sex, blood pressure and
blood sugar for chances of a patient getting heart disease. The data is analyzed and implemented in WEKA ("Waikato
Environment for Knowledge Analysis") tool. It is open source software which consists of a collection of machine learning
algorithms for data mining tasks. Data mining finds out the valuable information hidden in huge volumes of data. Weka tool is a
collection of machine learning algorithms for data mining techniques, written in Java. We have used 10 folds cross validation to
minimize any bias in the process and improve the efficiency of the process. The three classifiers like CART (Classification and
Regression Tree), ID3 (Iterative Dichotomized 3) and decision table (DT) were implemented in WEKA. The results show clearly
that the proposed method performs well compared to other similar methods in the literature, taking into the fact that the attributes
taken for analysis are not direct indicators of heart disease.
