Preparing a dataset for machine learning with scikit-learn

The first step to implementing any machine learning algorithm with scikit-learn is data preparation. Scikit-learn comes with a set of constraints to implementation that will be discussed later in this section. The dataset that we will be using is based on mobile payments and is found on the world's most popular competitive machine learning website – Kaggle.

You can download the dataset from: https://www.kaggle.com/ntnu-testimon/paysim1.

Once downloaded, open a new Jupyter Notebook by using the following code in Terminal (macOS/Linux) or Anaconda Prompt/PowerShell (Windows):

Jupyter Notebook

The fundamental goal of this dataset is to predict whether a mobile transaction is fraudulent. In order to do this, we need to first have a brief understanding of the contents of our data. In order to explore the dataset...
