Building a Fraud Detection System in Financial Transactions Using Isolation Forest
Introduction to Fraud Detection In the world of finance, fraud is a constant and evolving threat. As technology advances, so do the methods of fraudsters, making it a cat-and-mouse game between them and the financial institutions. One of the most effective ways to combat fraud is through the use of machine learning algorithms, particularly the Isolation Forest. What is Isolation Forest? Isolation Forest is an unsupervised learning algorithm designed to identify anomalies or outliers in a dataset. It works by creating multiple decision trees that partition the data, and the idea is that anomalies will be isolated more quickly than normal data points. This makes it an excellent choice for detecting fraudulent transactions, which often stand out as anomalies in financial data. ...
