Discover experiments in Cortana Intelligence Gallery

Cortana Intelligence Gallery is a community-driven site for discovering and sharing solutions built with Cortana Intelligence Suite. The Gallery has a variety of resources that you can use to develop your own analytics solutions.

Experiments for Machine Learning Studio

The Gallery has a wide variety of experiments that have been developed in Azure Machine Learning Studio. Experiments range from quick proof-of-concept experiments that demonstrate a specific machine learning technique, to fully developed solutions for complex machine learning problems.

Note

An experiment is a canvas in Machine Learning Studio that you can use to construct a predictive analysis model. You create the model by connecting data with various analytical modules. You can try different ideas, do trial runs, and eventually deploy your model as a web service in Azure. For an example of how to create a basic experiment, see Machine learning tutorial: Create your first experiment in Azure Machine Learning Studio. For a more comprehensive walkthrough of how to create a predictive analytics solution, see Walkthrough: Develop a predictive analytics solution for credit risk assessment in Azure Machine Learning.

Download

You can download a copy of any experiment in the Gallery to your Machine Learning Studio workspace. Then, you can modify your copy to create your own solutions.

Cortana Intelligence Gallery offers two ways to import a copy of an experiment:

  • From the Gallery. If you find an experiment that you like in the Gallery, you can download a copy and then open it in your Machine Learning Studio workspace.
  • From within Machine Learning Studio. In Machine Learning Studio, you can use any experiment in the Gallery as a template to create a new experiment.
  1. In the Gallery, open the experiment details page.
  2. Select Open in Studio.

    Open experiment from the Gallery

When you select Open in Studio, the experiment opens in your Machine Learning Studio workspace. (If you're not already signed in to Machine Learning Studio, you are prompted to first sign in by using your Microsoft account.)

From within Machine Learning Studio

  1. In Machine Learning Studio, select NEW.
  2. Select Experiment. You can choose from a list of Gallery experiments, or find a specific experiment by using the Search box.
  3. Point your mouse at an experiment, and then select Open in Studio. (To see information about the experiment, select View in Gallery. This takes you to the experiment details page in the Gallery.)

    Open Gallery experiment from inside Machine Learning Studio

You can customize, iterate, and deploy a downloaded experiment like any other experiment that you create in Machine Learning Studio.

Contribute

When you sign in to the Gallery, you become a member of the Gallery community. As a member of the community, you can contribute your own experiments, so other users can benefit from the solutions that you've discovered.

  1. Sign in to Machine Learning Studio by using your Microsoft account.
  2. Create your experiment, and then run it.
  3. When you’re ready to publish your experiment in the Gallery, in the list of actions below the experiment canvas, select Publish to Gallery.

    Select "Publish to Gallery"

  4. On the Experiment Description page, enter a title and tags. Make the title and tags descriptive. Highlight the techniques you used or the real-world problem you are solving. An example of a descriptive experiment title is “Binary Classification: Twitter Sentiment Analysis.”

    Enter title and tags for publishing

  5. In the SUMMARY box, enter a summary of your experiment. Briefly describe the problem the experiment solves, and how you approached it.
  6. In the DETAILED DESCRIPTION box, describe the steps you took in each part of your experiment. Some useful topics to include are:

    • Experiment graph screenshot
    • Data sources and explanation
    • Data processing
    • Feature engineering
    • Model description
    • Results and evaluation of model performance

    You can use markdown to format your description. To see how your entries on the experiment description page will look when the experiment is published, select Preview.

    Select "Preview" to see what your text will look like

    Tip

    The text boxes provided for markdown editing and preview are small. We recommend that you write your experiment documentation in a markdown editor, copy it, and then paste the completed documentation in the text box in the Gallery. After you publish your experiment, you can make any corrections by using standard web-based tools that use markdown for edit and preview.

  7. On the Image Selection page, choose a thumbnail image for your experiment. The thumbnail image appears at the top of the experiment details page and in the experiment tile. Other users will see the thumbnail image when they browse the Gallery. You can upload an image from your computer, or select a stock image from the Gallery.
    Upload or select an image for the Gallery

  8. On the Settings page, under Visibility, choose whether to publish your content publicly (Public) or to have it accessible only to people who have a link to the page (Unlisted).

    Choose whether to publish publicly or as unlisted

    Tip

    If you want to make sure your documentation looks correct before you release it publicly, you can first publish the experiment as Unlisted. Later, you can change the visibility setting to Public on the experiment details page.

  9. To publish the experiment to the Gallery, select the OK check mark.

    Select the OK check mark to publish the experiment

Tips for documenting and publishing your experiment

  • You can assume that the reader has prior data science experience, but it can be helpful to use simple language. Explain things in detail whenever possible.
  • Cortana Intelligence Suite is relatively new. Not all readers are familiar with how to use it. Provide enough information and step-by-step explanations to help readers navigate your experiment.
  • Visuals can be helpful for readers to interpret and use your experiment documentation correctly. Visuals include experiment graphs and screenshots of data. For more information about how to include images in your experiment documentation, see the Publishing Guidelines and Examples collection.
  • If you include a data set in your experiment (that is, you're not importing the dataset through the Import Data module), the data set is part of your experiment and is published in the Gallery. Make sure that the data set you publish has licensing terms that allow sharing and downloading by anyone. Gallery contributions are covered under the Azure Terms of Use.

Frequently asked questions

What are the requirements for submitting or editing an image for my experiment?

Images that you submit with your experiment are used to create an experiment tile for your contribution. We recommend that images be smaller than 500 KB, with an aspect ratio of 3:2, and a resolution of 960 × 640.

What happens to the data set I used in the experiment? Is the data set also published in the Gallery?

If your data set is part of your experiment and is not being imported through the Import Data module, the data set is published in the Gallery as part of your experiment. Make sure that the data set that you publish with your experiment has the appropriate licensing terms. The licensing terms should allow anyone to share and download the data.

I have an experiment that uses an Import Data module to pull data from Azure HDInsight or SQL Server. It uses my credentials to retrieve the data. Can I publish this kind of experiment? How can I be assured that my credentials won't be shared?

Currently, you cannot publish an experiment that uses credentials in the Gallery.

How do I enter multiple tags?

After you enter a tag, to enter another tag, press the Tab key.
