Question 286

You manage an Azure Machine Learning workspace named workspace1 and a Data Science Virtual Machine (DSVM) named DSMV1.
You must an experiment in DSMV1 by using a Jupiter notebook and Python SDK v2 code. You must store metrics and artifacts in workspace 1 You start by creating Python SCK v2 code to import ail required packages.
You need to implement the Python SOK v2 code to store metrics and article in workspace1.
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 the correctly order.

Question 287

You define a datastore named ml-data for an Azure Storage blob container. In the container, you have a folder named train that contains a file named data.csv. You plan to use the file to train a model by using the Azure Machine Learning SDK.
You plan to train the model by using the Azure Machine Learning SDK to run an experiment on local compute.
You define a DataReference object by running the following code:

You need to load the training data.
Which code segment should you use?
  • Question 288

    You are developing a machine learning, experiment by using Azure. The following images show the input and output of a machine learning experiment:

    Use the drop-down menus to select the answer choice that answers each question based on the information presented in the graphic.
    NOTE: Each correct selection is worth one point.

    Question 289

    You have a dataset created for multiclass classification tasks that contains a normalized numerical feature set with 10,000 data points and 150 features.
    You use 75 percent of the data points for training and 25 percent for testing. You are using the scikit-learn machine learning library in Python. You use X to denote the feature set and Y to denote class labels.
    You create the following Python data frames:
    You need to apply the Principal Component Analysis (PCA) method to reduce the dimensionality of the feature set to 10 features in both training and testing sets.
    How should you complete the code segment? To answer, select the appropriate options in the answer area.
    NOTE: Each correct selection is worth one point.

    Question 290

    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,I
    1,1,2,0
    2,1,1,1
    3,2,1,0
    4,2,2,1
    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?
