Demonstrates the use of ML for Anomaly Detection for Credit Card Transactions: Identifying Fraudulent Activity using Imbalanced Data

Credit Card Fraud Detection Using Machine Learning

Credit Card Fraud detection based on anonymized data using multiple classification algorithms

Imbalanced data commonly exist in real world, especially in anomaly-detection tasks. Handling imbalanced data is important to the tasks, otherwise the predictions are biased towards the majority class. RandomUnderSampler, ClusterCentroids, CondensedNearestNeighbour, and etc. are useful undersampling tools to remove data for majority classes.

The aim of this project is to determine which classification technique produces the best results when applied to the task of determining credit riskiness.
