Designing and Implementing a Data Science Solution on Azure — Question 138

You have an Azure Machine Learning workspace.

You plan to tune a model hyperparameter when you train the model.

You need to define a search space that returns a normally distributed value.

Which parameter should you use?

Answer options

• A. QUniform
• B. LogUniform
• C. Uniform
• D. LogNormal

Correct answer: D

Explanation

The correct choice is D, LogNormal, as it generates values that follow a normal distribution. Options A, B, and C do not provide normally distributed outputs; QUniform and Uniform yield uniform distributions, while LogUniform produces values that scale logarithmically.
