Overview of this book

Machine Learning (ML) has changed the way organizations and individuals use data to improve the efficiency of a system. ML algorithms allow strategists to deal with a variety of structured, unstructured, and semi-structured data. Machine Learning for Healthcare Analytics Projects is packed with new approaches and methodologies for creating powerful solutions for healthcare analytics. This book will teach you how to implement key machine learning algorithms and walk you through their use cases by employing a range of libraries from the Python ecosystem. You will build five end-to-end projects to evaluate the efficiency of Artificial Intelligence (AI) applications for carrying out simple-to-complex healthcare analytics tasks. With each project, you will gain new insights, which will then help you handle healthcare data efficiently. As you make your way through the book, you will use ML to detect cancer in a set of patients using support vector machines (SVMs) and k-Nearest neighbors (KNN) models. In the final chapters, you will create a deep neural network in Keras to predict the onset of diabetes in a huge dataset of patients. You will also learn how to predict heart diseases using neural networks. By the end of this book, you will have learned how to address long-standing challenges, provide specialized solutions for how to deal with them, and carry out a range of cognitive tasks in the healthcare domain.

Generating predictions using optimal hyperparameters

We know now some optimal hyperparameters for our grid search. We will use these to predict the onset of diabetes for the patients in our dataset. To do this, we will carry out the following steps:

  1. We will predict whether diabetes will occur for every example in the dataset by using the predict() function, as shown in the following code snippet:
# generate predictions with optimal hyperparameters
y_pred = grid.predict(X_standardized)
  1. We will then use the .shape command to see what the predictions look like. The following screenshot shows the output for this step:

From the preceding screenshot, we can see that there are 392 predictions with a numerical value for each.

  1. Let's print off the first five and see what they look like. We get the following output:
  1. We are now going to do a classification report and get an...
