Overview of the dataset

The dataset used in this chapter is the Credit Card Transactions Fraud Detection Dataset available on Kaggle at the following URL: https://www.kaggle.com/kartik2112/fraud-detection?select=fraudTrain.csv.

The dataset is made up of simulated credit card transactions containing legitimate and fraudulent transactions for the period January 1, 2019 – December 31, 2020. It includes the credit cards of 1,000 customers performing transactions with a pool of 800 merchants. The dataset was generated using Sparkov Data Generation. More information about the generation algorithm is available at the following URL: https://github.com/namebrandon/Sparkov_Data_Generation.

For each transaction, the dataset contains 23 different features. In the following table, we will show only the information that will be used in this chapter:

Table 8.1 – List of variables used in the dataset

For the purposes of our analysis, we will use the fraudTrain...
