Fraud Detection with Supervised Learning

The project aims to develop a baseline fraud detection system to identify potentially fraudulent credit card transactions. Utilising supervised learning techniques, this project serves as a foundational model for understanding and addressing credit card fraud issues faced by financial institutions.

If you find this project useful, please consider giving it a star ⭐ on GitHub. Contributions are also welcome!

Table of Contents

Technologies Used

  • Python: Programming language used for development.
  • FastAPI: Framework for building the API.
  • Scikit-learn: Machine learning library used for model training.
  • Pandas: Data manipulation library.
  • NumPy: Library for numerical operations.
  • Joblib: Library for model serialisation.

Getting Started

To get a local copy of this project up and running, follow these steps:

Installation

  1. Clone the repository:
   git clone https://github.com/nafisalawalidris/Fraud-Detection-with-Supervised-Learning.git
  1. Navigate to the project directory:
cd Fraud-Detection-with-Supervised-Learning
  1. Create a virtual environment:
python -m venv fraud_detection_env
  1. Activate the virtual environment:
  • On Windows:
.\fraud_detection_env\Scripts\activate
  • On macOS/Linux
source fraud_detection_env/bin/activate
  1. Install the required packages:
pip install -r requirements.txt

Usage

  1. Run the FastAPI server:
uvicorn main:app --reload

Then open your browser and go to http://localhost:8501.

  1. Send a POST request to the /predict endpoint with transaction data in the following format:
{
    "Time": 123456,
    "V1": 0.0,
    "V2": 1.0,
    ...
    "Amount": 100.00
}
  1. Receive a response with fraud prediction and probability:
{
    "fraud_prediction": true,
    "fraud_probability": 0.95
}

Features

  • Simple and effective fraud detection using supervised learning techniques.
  • RESTful API built with FastAPI for easy integration.
  • Detailed logging of predictions and transactions.
  • Well-structured codebase that allows for easy modifications and enhancements.
