Model Description

Keras Implementation of Imbalanced classification: credit card fraud detection

This repo contains the trained model of Imbalanced classification: credit card fraud detection.
The full credit goes to: fchollet

Intended uses & limitations

• The trained model is used to detect of a specific transaction is fraudulent or not.

Training dataset

• Credit Card Fraud Detection
• Due to the high imbalance of the target feature (417 frauds or 0.18% of total 284,807 samples), training weight was applied to reduce the False Negatives to the lowest level as possible.
