Production ML for practitioners: How to accelerate model training with LightGBM & Optuna

Fraud detection is a prevalent use case for machine learning (ML). In this tutorial, we will build an end-to-end ML pipeline using Snowflake's Snowpark and Aporia. We will train and evaluate models to detect fraudulent activities effectively. The key steps involved in the process include data understanding, data preparation, model training, evaluation, and deployment. While modeling is not the most time-consuming step, it is crucial to optimize the ML pipeline for efficiency. Tools like LightGBM and Optuna can significantly reduce the time spent on hyperparameter search and improve overall performance. By leveraging these tools and following best practices, we can create robust and efficient fraud detection systems using machine learning.
