This book will help you to build real-world machine learning solutions across the healthcare vertical using NumPy, pandas, matplotlib, scikit-learn, and so on. You need not have any prior knowledge before exploring this book. You will get well versed on how exactly machine learning is implemented to evaluate the efficiency of AI apps, and how to carry out simple-to-complex healthcare analytics tasks. This is a perfect entry point packed with practical examples to carry out a range of cognitive tasks. By the end of this book, you will have learned how to address long-standing challenges in the healthcare domain, and produce solutions for dealing with them.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "We will then rename that file autism_detection."

A block of code is set as follows:

import sys
import pandas as pd
import sklearn
import keras
print 'Python: {}'.format(sys.version)
print 'Pandas: {}'.format(pd.__version__)
print 'Sklearn: {}'.format(sklearn.__version__)
print 'Keras: {}'.format(keras.__version__)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[default]
exten => s,1,Dial(Zap/1|30)
exten => s,2,Voicemail(u100)
exten => s,102,Voicemail(b100)
exten => i,1,Voicemail(s0)

Any command-line input or output is written as follows:

jupyter lab

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "If we go into Files, we will see all the files that we have in the directory, as shown in the following screenshot."
