Computer Science Dept. [View Context].Lorne Mason and Peter L. Bartlett and Jonathan Baxter. Several features such as the day of the exercise reading, or the ID of the patient are unlikely to be relevant in predicting heart disease. Another possible useful classifier is the gradient boosting classifier, XGBoost, which has been used to win several kaggle challenges. See if you can find any other trends in heart data to predict certain cardiovascular events or find any clear indications of heart health. Analysis Heart Disease Using Machine Learning Mashael S.

Evaluating the Replicability of Significance Tests for Comparing Learning Algorithms. IEEE Trans. Although there are some features which are slightly predictive by themselves, the data contains more features than necessary, and not all of these features are useful.

To narrow down the number of features, I will use the sklearn class SelectKBest. 2000. 2004. Diversity in Neural Network Ensembles. We can also see that the column 'prop' appear to both have corrupted rows in them, which will need to be deleted from the dataframe. I will test out three popular models for fitting categorical data, logistic regression, random forests, and support vector machines using both the linear and rbf kernel.
