3.3. Azure Machine Learning Capabilities

💡 First Principle: Azure Machine Learning automates the tedious parts of ML (algorithm selection, hyperparameter tuning, model evaluation) while requiring you to handle the irreducible parts (data preparation, business understanding). Knowing what AutoML does—and doesn't—do is essential for exam success.

What breaks without understanding Azure ML: Questions ask "Which Azure ML capability automatically selects the best algorithm?" or "What does AutoML eliminate the need for?" If you think AutoML does everything, you'll miss that it still requires you to provision resources and prepare data. If you think it does nothing, you'll miss its core value: automated model selection and training.

Think of Azure ML like a cooking show where chefs compete. AutoML is like having judges who taste every dish and pick the winner—you still have to grow the ingredients (prepare data) and plate the food (deploy the model), but you don't have to taste-test every possible recipe combination yourself. This automation saves enormous time while leaving you in control of the business decisions.

Building on the Azure AI Service Model from Section 1.4, let's examine Azure Machine Learning's specific capabilities for building and deploying ML models.
