Introduction

In this blog post, I will use 6 different classification algorithms to predict mortality with heart failure.

To do so, we will use classification algorithms.

Here are the algorithms that I will use;

  • Random Forest
  • Logistic Regression
  • KNN
  • Decision Tree
  • SVM
  • Naive Bayes

And after that, I will compare the results according to the;

  • Accuracy
  • Precision
  • Recall
  • F1 score.

That will be longer than my other blog post, yet after reading this article, you will probably have a huge knowledge about Machine Learning Classification Algorithms and Evaluation metrics.

If you want to know more about Machine Learning terms, here is my blog post, Machine Learning A-Z Briefly Explained.

Now let’s start with the data.
