A window function is an analytic function, typically run in SQL and SQL-based engines such as Hive, Impala, and Spark , which allows one to perform aggregate calculations across a set of table rows, while retaining the same row structure. Some examples of computations that can be performed using a window function are moving averages, cumulative sums, and rankings. The visual Window recipe in Dataiku allows you to take advantage of this powerful function without coding.

The Window recipe is different from the Group recipe. The Window recipe groups your rows together, but instead of reducing the rows to just the aggregated rows, it keeps all of the rows and organizes them into a window frame based on how you configure it. Defining the window s : On what rows of the dataset will the computations apply? Partitioned: Define one or several columns, and one window is created for each combination of values of these columns. Ordered: Define one or several columns to order the windowed rows by typically a date, a ranking, etc.

Bounded: For each row, restrict the window to only take into account the following:. This binary classification problem uses a dataset of both labeled transactions known to have passed or failed authorization, as well as unknown transactions. This lesson assumes that you have basic knowledge of working with Dataiku DSS datasets and recipes. If not already on the Advanced Designer learning path, completing the Core Designer Certificate is recommended.

Census USA minimum version 0. Reverse geocoding. These plugins are available through the Dataiku Plugin store, and you can find the instructions for installing plugins in the reference documentation. To check whether the plugin is already installed on your instance, go to the Installed tab in the Plugin Store to see a list of all installed plugins. Users of Dataiku Online should note that while plugin installation is not directly available, you can still explore available plugins from your launchpad :.

In order to get the most out of this lesson, we recommend completing the following lessons beforehand:.

Concept: Window Recipe. Concept: Common Steps in Recipes. You can also download the starter project from this website and import it as a zip file. You are welcome to leave the storage connection of these datasets in place, but you can also use another storage system depending on the infrastructure available to you.

For a dataset that is already built, changing to a new connection clears the dataset so that it would need to be rebuilt. Click Build to start the job, or click Preview to view the suggested job. If previewing, in the Jobs tab, you can see all the activities that Dataiku will perform. Each row represents one transaction, consisting of the following notable columns:. These new columns could potentially be valuable features helping to predict which transactions will fail authorization. This is because some rows represent refunds made by the merchant to the cardholder.

In other words, the known outcome in the training data is used to predict whether each unknown transaction was authorized or not. What kind of aggregations should we compute? On which groups? And over what kind of window? We might want to know the minimum, maximum, and average purchase amount for every cardholder. We might want to know the same for every merchant.

These kinds of questions we can answer with just a Group recipe. The Window recipe allows us to calculate these kinds of aggregations for some group, for some particular window of rows. For example, the Window recipe can tell us the average purchase amount for every cardholder during some time period with respect to the present transaction.

That is, on any particular date, the aggregations will include all past transactions, but no future transactions from after that date. For our first window, we are interested in computing aggregations by cardholder i. To do this:. This way, when you look at all of the transactions for a given card in your output dataset, the most recent ones will display at the top.

Using a Window frame allows you to limit the number of rows taken into account to compute aggregations. If we were to select Limit window on a value range from the order column , we would be limiting the number of rows to compute aggregations based on the order column. For example, if we selected to order by date, we could choose to only compute aggregations on the transactions from the past six months. Finally, since we are going to define two windows in this recipe, add the prefix card to make the aggregated columns easier to recognize.

Here you can select the columns you want to retrieve and compute aggregations on. At the moment, all of the columns from the input dataset are selected by default to be retrieved in the output dataset. This will create three new columns in the output dataset. You can verify this by going to the Output step from the left menu:. It would be useful to have both the aggregations by card and by merchant appear in the same output dataset, so that we can compare them and potentially use them as features in our machine learning model.

You could create a new Window recipe from the output dataset of this one, but it would be easier and faster to do it as part of the same recipe—Dataiku DSS allows us to do that.

Activate Window Frame , limiting the preceding rows to be taken into account to 0. Give this window the prefix merchant. You can verify that the output columns all contain the correct prefix and are understandable to you or, if not, change their names in the Output step:. Many visual recipes offer the option of pre- and post-filter steps in addition to windowing, grouping, joining, splitting, etc. Whether a pre- or post-filter step is the right choice depends on a variety of factors, such as transparency, efficiency, and Flow management.

Notice there are six new columns, each containing aggregated statistics about the minimum, maximum, and average purchase amount by card and by merchant respectively, and ordered by date in descending order. Check one of the card ID boxes to display all the transactions made with one particular credit card. The last objective of this tutorial is to compute aggregated statistics using the Window recipe to generate additional potential features for the machine learning model.

When you click Save after changing the input dataset to the Split recipe, pay close attention to the schema change notification. Dataiku has detected a change in the number of columns, and so recommends to drop and recreate the two output datasets. This is because we accepted the drop and recreate option in the schema update.

These datasets will need to be rebuilt if we actually want to use these features in model training! In the optional Window Recipe: Deep Dive hands-on, you can apply your knowledge to even more advanced usages of the Window recipe. Concept: The Lab Where can I see how many records are in my entire dataset?

How to create a Jira issue automatically upon a DSS scenario execution failure Can I control which datasets in my Flow get rebuilt during a scenario? You are viewing the Knowledge Base for version Windowing in Dataiku Concept Recap. Tip Users of Dataiku Online should note that while plugin installation is not directly available, you can still explore available plugins from your launchpad : From your instance launchpad, open the Features panel on the left hand side.

Note You can also download the starter project from this website and import it as a zip file. Note For a dataset that is already built, changing to a new connection clears the dataset so that it would need to be rebuilt.

The screenshots below demonstrate using a PostgreSQL database. Next, activate Order Columns. This will allow you to order each grouping of aggregated rows by a certain criteria.

Finally, activate Window Frame. Note If we were to select Limit window on a value range from the order column , we would be limiting the number of rows to compute aggregations based on the order column. On the left hand panel, click on Aggregations.

Click on Post-filter on the left menu, and then activate the filter. Note Many visual recipes offer the option of pre- and post-filter steps in addition to windowing, grouping, joining, splitting, etc.

Calculating a cumulative sum, however, does. In other words, we want to compute the cumulative distribution of the summed purchase amount.

Activate the Window Frame , and limit the number of following rows to 0. Since the window is ordered by purchase date and framed so as to not take into account following rows, this will compute the sum of the purchase amount of all previous transactions, plus the current one, for each transaction.

Un-select Use same sample as Explore , and instead choose No sampling whole data. By selecting MAX as the aggregation, we look at the evolution in the cumulative sum of all purchase amounts at the end of each period. Activate the Window Frame , and limit the preceding rows to 3 to include the three prior purchases and the following rows to 0 which includes the present row in the window frame. The aggregation should already be set to AVG. Instead of finding the average and sum of the three most recent purchases for every card, we might instead want to know about the sum and average of any number of purchases in the past three days on that card.

Change the Window Frame setting to Limit window on a value range of the order column. Set the lower bound to 3 and the upper bound this time to -1 days This will exclude the present row. For any card, there is no guarantee of a purchase every day, and so, the three previous rows and the three most recent days are not necessarily the same. When working with an irregular time series like this one, you might resample the data so no dates in the series are missing.
