Fraud Detection for E-Commerce and Banking Transactions

Overview

This project aims to improve the detection of fraud cases in e-commerce and bank credit transactions. By using advanced machine learning models and detailed data analysis, we can accurately spot fraudulent activities and reduce financial losses.

Features

• Data preprocessing and feature engineering
• Fraud detection using machine learning models
• Real-time model deployment for fraud detection
• Continuous model evaluation and improvements

Technologies & Tools:

• Python 3.x
• Machine Learning Libraries: Scikit-learn, TensorFlow, XGBoost
• Data Analysis & Preprocessing: Pandas, NumPy
• Geolocation Analysis: GeoPy, Geopandas
• Visualization: Matplotlib, Seaborn, Plotly
• Deployment: Flask (for model deployment), Docker (for containerization)
• Version Control: Git, GitHub

Features:

• Transaction Data Preprocessing: Clean and transform raw transaction data for machine learning model input.
• Fraud Detection Models: Using classification algorithms to predict fraud.
• Geolocation Analysis: Leveraging location-based features to identify suspicious activities.
• Real-time Fraud Detection: Deployed models for immediate fraud detection during transactions.

Getting Started

Prerequisites

Before you begin, ensure you have the following tools installed:

• Python 3.x
• VS Code
• Git
• Jupyter Notebook (Optional for notebook-based analysis)

Installation

1. Clone the repository:

   git clone https://github.com/hydropython/FraudX-Real-Time-E-Commerce-and-Banking-Transaction-Protection.git
   cd Fraud-Detection-ECommerce-Banking
   

2. Set up a virtual environment:

   python -m venv env
   source env/bin/activate  # On Windows, use `env\Scripts\activate`
   

3. Install dependencies:

   pip install -r requirements.txt
   

4. Run the notebooks to explore, train, and evaluate models

5. Deployment Instructions

   python run.py
