Summary of Build Realtime Fraud Detection AI from Scratch - End to End Machine Learning Project - Part 1

Key Concepts and Features

• Architecture Setup:

  The course begins with setting up a production-ready architecture that integrates data engineering and data science practices. It involves producing data into a high-performance cloud-based cluster, specifically using Apache Kafka for data streaming.

• Model Training:

  The video details the process of training a model from scratch using data ingested through Kafka. Apache Airflow is utilized for scheduling and managing the retraining of the model at specified intervals (e.g., 3:00 AM).

• Model Versioning:

  The system tracks different versions of the model based on their precision scores. Only models that improve upon previous versions are promoted to production. The model's performance is evaluated using metrics such as precision, accuracy, and F1 score.

• Data Inference:

  Once trained, the model is used to infer whether incoming transactions are fraudulent. The results can be sent to various outputs, such as a dashboard or notification systems (e.g., Slack, Telegram).

• Technological Stack:
  • Apache Kafka: Used for real-time data streaming.
  • Apache Airflow: Manages workflows and schedules model retraining.
  • MLflow: Tracks experiments and manages model versions.
  • MinIO: Serves as an S3-compatible object storage for model artifacts.
• Data Handling:

  The course emphasizes the importance of correctly labeling data, particularly identifying fraudulent transactions, which typically represent a small percentage (1-2%) of the total transactions. It discusses class imbalance handling techniques to ensure the model learns effectively from the data.

• System Requirements:

  The video outlines both local and production system requirements, including CPU, RAM, and storage specifications necessary for running the project efficiently.

• Hands-On Coding:

  The video includes practical coding examples for setting up the environment, configuring Docker containers, and implementing the model training logic. It encourages viewers to troubleshoot and resolve issues encountered during the setup process.

Conclusion

The video serves as an introduction to building a real-time fraud detection system, combining various data engineering and machine learning practices. It provides foundational knowledge and practical coding examples to help viewers understand the components involved in such a project.
