 ## Overview
 
-This workshop introduces you to foundational workflows in **AWS SageMaker**, covering data setup, model training, hyperparameter tuning, and model deployment within AWS's managed environment. You’ll learn how to use SageMaker notebooks to control data pipelines, manage training jobs, and evaluate model performance effectively. We’ll also cover strategies to help you scale training and tuning efficiently, with guidance on choosing between CPUs and GPUs, as well as when to consider parallelized training.

-To keep costs manageable, this workshop provides tips for tracking and monitoring AWS expenses, so your experiments remain affordable. While AWS isn’t entirely free, it’s very cost-effective for typical ML workflows—training roughly 100 models on a small dataset (under 10GB) can cost under $20, making it accessible for many research projects.
