Fraud Classification Model and Deployment

For this project, I developed and deployed a fraud classification model using multiple machine learning models, including Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Naïve Bayes, Multi-Layer Perceptron (MLP), and XGBoost.

Key Steps:

• Data Preparation: Processed a credit card transaction dataset to identify fraudulent activities.
• Model Training: Trained multiple classifiers to detect fraud, optimizing them for accuracy and efficiency.
• Model Evaluation: Compared model performances to determine the best approach.
• Deployment: Built APIs using FastAPI and Flask to serve real-time fraud detection predictions.
• Testing: Used Postman to validate the API responses. Python Machine Learning Model
