Using a dataset of of nearly 28,500 credit card transactions and multiple unsupervised anomaly detection algorithms, I identified transactions with a high probability of being credit card fraud. In this project, I built and deployed the following two machine learning algorithms:
-
Local Outlier Factor (LOF)
-
Isolation Forest Algorithm
Furthermore, I used metrics suchs as precision, recall, and F1-scores.
In addition, I explored parameter histograms and correlation matrices.
