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 free account
• 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 ml.azure.com, 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 run.

   Depending on the sample pipeline and compute settings, runs 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 runs 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). UCI Machine Learning Repository. 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). UCI Machine Learning Repository. 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 Dataset Shared	This data comes from the KDD Cup 2009 customer relationship prediction challenge (orange_small_train.data.zip). The dataset contains 50K customers from the French Telecom company Orange. Each customer has 230 anonymized features, 190 of which are numeric and 40 are categorical. The features are very sparse.
CRM Upselling Labels Shared	Labels from the KDD Cup 2009 customer relationship prediction challenge (orange_large_train_upselling.labels
Flight Delays Data	Passenger flight on-time performance data taken from the TranStats data collection of the U.S. Department of Transportation (On-Time). The dataset covers the time period April-October 2013. Before uploading to the designer, the dataset was processed as follows: - The dataset was filtered to cover only the 70 busiest airports in the continental US - Canceled flights were labeled as delayed by more than 15 minutes - Diverted flights were filtered out - The following columns were selected: Year, Month, DayofMonth, DayOfWeek, Carrier, OriginAirportID, DestAirportID, CRSDepTime, DepDelay, DepDel15, CRSArrTime, ArrDelay, ArrDel15, Canceled
German Credit Card UCI dataset	The UCI Statlog (German Credit Card) dataset (Statlog+German+Credit+Data), using the german.data file. The dataset classifies people, described by a set of attributes, as low or high credit risks. Each example represents a person. There are 20 features, both numerical and categorical, and a binary label (the credit risk value). High credit risk entries have label = 2, low credit risk entries have label = 1. The cost of misclassifying a low risk example as high is 1, whereas the cost of misclassifying a high risk example as low is 5.
IMDB Movie Titles	The dataset contains information about movies that were rated in Twitter tweets: IMDB movie ID, movie name, genre, and production year. There are 17K movies in the dataset. The dataset was introduced in the paper "S. Dooms, T. De Pessemier and L. Martens. MovieTweetings: a Movie Rating Dataset Collected From Twitter. Workshop on Crowdsourcing and Human Computation for Recommender Systems, CrowdRec at RecSys 2013."
Movie Ratings	The dataset is an extended version of the Movie Tweetings dataset. The dataset has 170K ratings for movies, extracted from well-structured tweets on Twitter. Each instance represents a tweet and is a tuple: user ID, IMDB movie ID, rating, timestamp, number of favorites for this tweet, and number of retweets of this tweet. The dataset was made available by A. Said, S. Dooms, B. Loni and D. Tikk for Recommender Systems Challenge 2014.
Weather Dataset	Hourly land-based weather observations from NOAA (merged data from 201304 to 201310). The weather data covers observations made from airport weather stations, covering the time period April-October 2013. Before uploading to the designer, the dataset was processed as follows: - Weather station IDs were mapped to corresponding airport IDs - Weather stations not associated with the 70 busiest airports were filtered out - The Date column was split into separate Year, Month, and Day columns - The following columns were selected: AirportID, Year, Month, Day, Time, TimeZone, SkyCondition, Visibility, WeatherType, DryBulbFarenheit, DryBulbCelsius, WetBulbFarenheit, WetBulbCelsius, DewPointFarenheit, DewPointCelsius, RelativeHumidity, WindSpeed, WindDirection, ValueForWindCharacter, StationPressure, PressureTendency, PressureChange, SeaLevelPressure, RecordType, HourlyPrecip, Altimeter
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).
