Question 121

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 122

You are evaluating a completed binary classification machine.
You need to use the precision as the evaluation metric.
Which visualization should you use?
  • Question 123

    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.
    An IT department creates the following Azure resource groups and resources:

    The IT department creates an Azure Kubernetes Service (AKS)-based inference compute target named aks-cluster in the Azure Machine Learning workspace. You have a Microsoft Surface Book computer with a GPU. Python 3.6 and Visual Studio Code are installed.
    You need to run a script that trains a deep neural network (DNN) model and logs the loss and accuracy metrics.
    Solution: Install the Azure ML SDK on the Surface Book. Run Python code to connect to the workspace. Run the training script as an experiment on the aks-cluster compute target.
    Does the solution meet the goal?
  • Question 124

    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 create an Azure Machine Learning service datastore in a workspace. The datastore contains the following files:
    * /data/2018/Q1 .csv
    * /data/2018/Q2.csv
    * /data/2018/Q3.csv
    * /data/2018/Q4.csv
    * /data/2019/Q1.csv
    All files store data in the following format:
    id,f1,f2,l
    1,1,2,0
    2,1,1,1
    3.2.1.0
    You run the following code:

    You need to create a dataset named training_data and load the data from all files into a single data frame by using the following code:

    Solution: Run the following code:

    Does the solution meet the goal?
  • Question 125

    You are analyzing a raw dataset that requires cleaning.
    You must perform transformations and manipulations by using Azure Machine Learning Studio.
    You need to identify the correct modules to perform the transformations.
    Which modules should you choose? To answer, drag the appropriate modules to the correct scenarios. Each module 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.
