Example pipelines & datasets for Azure Machine Learning designer

Use the built-in examples in Azure Machine Learning designer to quickly get started building your own machine learning pipelines. The Azure Machine Learning designer GitHub repository contains detailed documentation to help you understand some common machine learning scenarios.

Prerequisites

• An Azure subscription. If you don't have an Azure subscription, create a Trial
• An Azure Machine Learning workspace

Use sample pipelines

The designer saves a copy of the sample pipelines to your studio workspace. You can edit the pipeline to adapt it to your needs and save it as your own. Use them as a starting point to jumpstart your projects.

Here's how to use a designer sample:

1. Sign in to studio.ml.azure.cn, and select the workspace you want to work with.

2. Select Designer.

3. Select a sample pipeline under the New pipeline section.

   Select Show more samples for a complete list of samples.

4. To run a pipeline, you first have to set default compute target to run the pipeline on.

   1. In the Settings pane to the right of the canvas, select Select compute target.

   2. In the dialog that appears, select an existing compute target or create a new one. Select Save.

   3. Select Submit at the top of the canvas to submit a pipeline job.

   Depending on the sample pipeline and compute settings, jobs may take some time to complete. The default compute settings have a minimum node size of 0, which means that the designer must allocate resources after being idle. Repeated pipeline jobs will take less time since the compute resources are already allocated. Additionally, the designer uses cached results for each component to further improve efficiency.

5. After the pipeline finishes running, you can review the pipeline and view the output for each component to learn more. Use the following steps to view component outputs:

   1. Right-click the component in the canvas whose output you'd like to see.
   2. Select Visualize.

   Use the samples as starting points for some of the most common machine learning scenarios.

Datasets

When you create a new pipeline in Azure Machine Learning designer, a number of sample datasets are included by default. These sample datasets are used by the sample pipelines in the designer homepage.

The sample datasets are available under Datasets-Samples category. You can find this in the component palette to the left of the canvas in the designer. You can use any of these datasets in your own pipeline by dragging it to the canvas.

Dataset name	Dataset description
Adult Census Income Binary Classification dataset	A subset of the 1994 Census database, using working adults over the age of 16 with an adjusted income index of > 100. Usage: Classify people using demographics to predict whether a person earns over 50K a year. Related Research: Kohavi, R., Becker, B., (1996). Irvine, CA: University of California, School of Information and Computer Science
Automobile price data (Raw)	Information about automobiles by make and model, including the price, features such as the number of cylinders and MPG, as well as an insurance risk score. The risk score is initially associated with auto price. It is then adjusted for actual risk in a process known to actuaries as symboling. A value of +3 indicates that the auto is risky, and a value of -3 that it is probably safe. Usage: Predict the risk score by features, using regression or multivariate classification. Related Research: Schlimmer, J.C. (1987). Irvine, CA: University of California, School of Information and Computer Science.
CRM Appetency Labels Shared	Labels from the KDD Cup 2009 customer relationship prediction challenge (orange_small_train_appetency.labels).
CRM Churn Labels Shared	Labels from the KDD Cup 2009 customer relationship prediction challenge (orange_small_train_churn.labels).
CRM Upselling Labels Shared	Labels from the KDD Cup 2009 customer relationship prediction challenge (orange_large_train_upselling.labels
Wikipedia SP 500 Dataset	Data is derived from Wikipedia (https://www.wikipedia.org/) based on articles of each S&P 500 company, stored as XML data. Before uploading to the designer, the dataset was processed as follows: - Extract text content for each specific company - Remove wiki formatting - Remove non-alphanumeric characters - Convert all text to lowercase - Known company categories were added Note that for some companies an article could not be found, so the number of records is less than 500.
Restaurant Feature Data	A set of metadata about restaurants and their features, such as food type, dining style, and location. Usage: Use this dataset, in combination with the other two restaurant datasets, to train and test a recommender system. Related Research: Bache, K. and Lichman, M. (2013). Irvine, CA: University of California, School of Information and Computer Science.
Restaurant Ratings	Contains ratings given by users to restaurants on a scale from 0 to 2. Usage: Use this dataset, in combination with the other two restaurant datasets, to train and test a recommender system. Related Research: Bache, K. and Lichman, M. (2013). Irvine, CA: University of California, School of Information and Computer Science.
Restaurant Customer Data	A set of metadata about customers, including demographics and preferences. Usage: Use this dataset, in combination with the other two restaurant datasets, to train and test a recommender system. Related Research: Bache, K. and Lichman, M. (2013). Irvine, CA: University of California, School of Information and Computer Science.

Clean up resources

Delete everything

If you don't plan to use anything that you created, delete the entire resource group so you don't incur any charges.

1. In the Azure portal, select Resource groups on the left side of the window.

   

2. In the list, select the resource group that you created.

3. Select Delete resource group.

Deleting the resource group also deletes all resources that you created in the designer.

Delete individual assets

In the designer where you created your experiment, delete individual assets by selecting them and then selecting the Delete button.

The compute target that you created here automatically autoscales to zero�nodes when it's not being used. This action is taken to minimize charges.�If you want to delete the compute target, take these steps:

You can unregister datasets from your workspace by selecting each dataset and selecting Unregister.

To delete a dataset, go to the storage account by using the Azure portal or Azure Storage Explorer and manually delete those assets.
