Microsoft Azure AI Fundamentals — Question 130

During the process of Machine Learning, when should you review evaluation metrics.

Answer options

• A. Before you train a model.
• B. After you clean the data.
• C. Before you choose the type of model.
• D. After you test a model on the validation data.

Correct answer: D

Explanation

The correct answer is D because evaluation metrics are crucial for determining how well a model performs after it has been tested on validation data. Options A, B, and C are incorrect as reviewing metrics before training, after cleaning, or before model selection does not provide insights into the model's performance.
