Question 51

You need to set up the Permutation Feature Importance module according to the model training requirements.
Which properties should you select? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Question 52

You have a model with a large difference between the training and validation error values.
You must create a new model and perform cross-validation.
You need to identify a parameter set for the new model using Azure Machine Learning Studio.
Which module you should use for each step? To answer, drag the appropriate modules to the correct steps.
Each module may be used once or 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.

Question 53

You design data engineering solutions for a company.
A project requires analytics and visualization of large set of data. The project has the following requirements:
- Notebook scheduling
- Cluster automation
- Power BI Visualization
You need to recommend the appropriate Azure service. Which Azure service should you recommend?
  • Question 54

    You create a training pipeline using the Azure Machine Learning designer. You upload a CSV file that contains the data from which you want to train your model.
    You need to use the designer to create a pipeline that includes steps to perform the following tasks:
    Select the training features using the pandas filter method.
    Train a model based on the naive_bayes.GaussianNB algorithm.
    Return only the Scored Labels column by using the query SELECT [Scored Labels] FROM t1; Which modules should you use? To answer, drag the appropriate modules to the appropriate locations. Each module name 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.

    Question 55

    You create a pipeline in designer to train a model that predicts automobile prices.
    Because of non-linear relationships in the data, the pipeline calculates the natural log (Ln) of the prices in the training data, trains a model to predict this natural log of price value, and then calculates the exponential of the scored label to get the predicted price.
    The training pipeline is shown in the exhibit. (Click the Training pipeline tab.) Training pipeline

    You create a real-time inference pipeline from the training pipeline, as shown in the exhibit. (Click the Real- time pipeline tab.) Real-time pipeline

    You need to modify the inference pipeline to ensure that the web service returns the exponential of the scored label as the predicted automobile price and that client applications are not required to include a price value in the input values.
    Which three modifications must you make to the inference pipeline? Each correct answer presents part of the solution.
    NOTE: Each correct selection is worth one point.
