Learning Artificial Neural Networks by predicting visitor purchase intention

As I am taking a course on Udemy on Deep Learning, I decided to put my knowledge to use and try to predict whether a visitor would make a purchase (generate revenue) or not. The dataset has been taken from UCI Machine Learning Repository. The first step is to import necessary libraries. Apart from the regular data science libraries including numpy, pandas and matplotlib, I import machine learning library sklearn and deep learning library keras. I will use keras to develop my Artificial Neural Network with tensorflow as the backend.
