DP-100 Exam Question 126

You are performing a filter based feature selection for a dataset 10 build a multi class classifies by using Azure Machine Learning Studio.
The dataset contains categorical features that are highly correlated to the output label column.
You need to select the appropriate feature scoring statistical method to identify the key predictors. Which method should you use?

    You need to modify the inputs for the global penalty event model to address the bias and variance issue.
    Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

    DP-100 Exam Question 128

    You plan to explore demographic data for home ownership in various cities. The data is in a CSV file with the following format:
    age,city,income,home_owner
    21,Chicago,50000,0
    35,Seattle,120000,1
    23,Seattle,65000,0
    45,Seattle,130000,1
    18,Chicago,48000,0
    You need to run an experiment in your Azure Machine Learning workspace to explore the data and log the results. The experiment must log the following information:
    the number of observations in the dataset
    a box plot of income by home_owner
    a dictionary containing the city names and the average income for each city You need to use the appropriate logging methods of the experiment's run object to log the required information.
    How should you complete the code? To answer, drag the appropriate code segments to the correct locations. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
    NOTE: Each correct selection is worth one point.

    DP-100 Exam Question 129

    Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
    After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
    You are creating a new experiment in Azure Machine Learning Studio.
    One class has a much smaller number of observations than the other classes in the training set.
    You need to select an appropriate data sampling strategy to compensate for the class imbalance.
    Solution: You use the Scale and Reduce sampling mode.
    Does the solution meet the goal?
  • DP-100 Exam Question 130

    You are running a training experiment on remote compute in Azure Machine Learning.
    The experiment is configured to use a conda environment that includes the mlflow and azureml-contrib-run packages.
    You must use MLflow as the logging package for tracking metrics generated in the experiment.
    You need to complete the script for the experiment.
    How should you complete the code? To answer, select the appropriate options in the answer area.
    NOTE: Each correct selection is worth one point.
