Anomaly Detection with Autoencoders - Credit Card Fraud Case
Blog post for this repo: https://blog.berkgokden.com
Code is based on: https://medium.com/swlh/anomaly-detection-with-autoencoders-2bd23dedbd9e Data: https://www.kaggle.com/mlg-ulb/creditcardfraud
Download data from Kaggle
To plot the input data:
python part1.py
To train the model and plot sample data:
python part2.py
Model will be saved as 'autoencoder.h5'.
The dataset has been collected and analysed during a research collaboration of Worldline and the Machine Learning Group (http://mlg.ulb.ac.be) of ULB (Université Libre de Bruxelles) on big data mining and fraud detection. More details on current and past projects on related topics are available on https://www.researchgate.net/project/Fraud-detection-5 and the page of the DefeatFraud project
