Question 206

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 model to predict the price of a student's artwork depending on the following variables: the student's length of education, degree type, and art form.
You start by creating a linear regression model.
You need to evaluate the linear regression model.
Solution: Use the following metrics: Relative Squared Error, Coefficient of Determination, Accuracy, Precision, Recall, F1 score, and AUC.
Does the solution meet the goal?

    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: Attach the mlvm virtual machine as a compute target in the Azure Machine Learning workspace.
    Install the Azure ML SDK on the Surface Book and run Python code to connect to the workspace. Run the training script as an experiment on the mlvm remote compute resource.
  • Question 208

    You are preparing to use the Azure ML SDK to run an experiment and need to create compute. You run the following code:

    For each of the following statements, select Yes if the statement is true. Otherwise, select No.
    NOTE: Each correct selection is worth one point.

    Question 209

    You use the Azure Machine Learning service to create a tabular dataset named training.dat a. You plan to use this dataset in a training script.
    You create a variable that references the dataset using the following code:
    training_ds = workspace.datasets.get("training_data")
    You define an estimator to run the script.
    You need to set the correct property of the estimator to ensure that your script can access the training.data dataset Which property should you set?
  • Question 210

    You create a multi-class image classification deep learning model.
    The model must be retrained monthly with the new image data fetched from a public web portal. You create an Azure Machine Learning pipeline to fetch new data, standardize the size of images, and retrain the model.
    You need to use the Azure Machine Learning SDK to configure the schedule for the pipeline.
    Which four 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.
