You create a binary classification model by using Azure Machine Learning Studio. You must tune hyperparameters by performing a parameter sweep of the model. The parameter sweep must meet the following requirements: ✑ iterate all possible combinations of hyperparameters ✑ minimize computing resources required to perform the sweep You need to perform a parameter sweep of the model. Which parameter sweep mode should you use? A. Random sweep B. Sweep clustering C. Entire grid D. Random grid Suggested Answer: D Maximum number of runs on random grid: This option also controls the number of iterations over a random sampling of parameter values, but the values are not generated randomly from the specified range; instead, a matrix is created of all possible combinations of parameter values and a random sampling is taken over the matrix. This method is more efficient and less prone to regional oversampling or undersampling. If you are training a model that supports an integrated parameter sweep, you can also set a range of seed values to use and iterate over the random seeds as well. This is optional, but can be useful for avoiding bias introduced by seed selection. Incorrect Answers: B: If you are building a clustering model, use Sweep Clustering to automatically determine the optimum number of clusters and other parameters. C: Entire grid: When you select this option, the module loops over a grid predefined by the system, to try different combinations and identify the best learner. This option is useful for cases where you don't know what the best parameter settings might be and want to try all possible combination of values.
