Credit Card Fraud Prediction

In the banking domain, predicting the credit card fraudulent activities it the key pressing issue.

With the increase in technology, the way fraud is happing is also changed into new ways.

So these actives need to detect with machine learning or deep learning algorithms.

This article will build the famous credit card fraud detection model using the Kaggle credit card data.

We will also learn how to handle the imbalance problems.
