Designing and Implementing a Data Science Solution on Azure — Question 99

You use Azure Machine Learning to train a model.

You must use Bayesian sampling to tune hyperparameters.

You need to select a learning_rate parameter distribution.

Which two distributions can you use? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Answer options

• A. Uniform
• B. Choice
• C. QNormal
• D. Normal
• E. LogUniform

Correct answer: A, B

Explanation

The correct answers are Uniform and Choice because both distributions are valid for defining a learning_rate parameter in Bayesian sampling. The Uniform distribution allows for a continuous range of values, while the Choice distribution enables selection from a predefined set of options. The other options, QNormal, Normal, and LogUniform, either don't fit the requirement for this context or are not typically used for this specific parameter tuning in Azure Machine Learning.
