Using a combination of FeatureBuilders and Aggregate Readers. Let's start with the readers. We define two readers for the two different tables as follows: - -```scala -val clicksReader = DataReaders.Aggregate.csvCase[Click]( - path = Some("src/main/resources/EmailDataset/Clicks.csv"), - key = _.userId.toString, - aggregateParams = AggregateParams( - timeStampFn = Some[Click => Long](c => formatter.parseDateTime(c.timeStamp).getMillis), - cutOffTime = CutOffTime.DDMMYYYY("04092017") - ) -) - -val sendsReader = DataReaders.Aggregate.csvCase[Send]( - path = Some("src/main/resources/EmailDataset/Sends.csv"), - key = _.userId.toString, - aggregateParams = AggregateParams( - timeStampFn = Some[Send => Long](s => formatter.parseDateTime(s.timeStamp).getMillis), - cutOffTime = CutOffTime.DDMMYYYY("04092017") - ) -) -``` - -There are a few different parameters of interest in these readers: -* The first is a ```key``` parameter, that specifies the key in the table that should be used to aggregate either the predictors or response variables. -* The second is a ```timeStampFn``` parameter that allows the user to specify a function for extracting timestamps from records in the table. This is the timestamp that will be used to compare against the reference time. -* And the third is a ```cutOffTime```, which is the reference time to be used. -All predictors will be aggregated from records up until the ```cutOffTime```, and all response variables will be aggregated from records following the ```cutOffTime```. - -Now let's look at how the predictors and response variables are defined. In this example, we define two aggregate predictors using TransmogrifAI's FeatureBuilders: - -```scala -val numClicksYday = FeatureBuilder.RealNN[Click] - .extract(click => 1.toRealNN) - .aggregate(SumRealNN) - .window(Duration.standardDays(1)) - .asPredictor - -val numSendsLastWeek = FeatureBuilder.RealNN[Send] - .extract(send => 1.toRealNN) - .aggregate(SumRealNN) - .window(Duration.standardDays(7)) - .asPredictor -``` -Here ```numClicksYday``` is a non-nullable real predictor, extracted from the Clicks table, by mapping each click to a ```1```, then aggregating for each key of the Click table by summing up the ```1's``` that occur in a 1 day window before the ```cutOffTime``` specified in the ```clicksReader```. - -Similarly, ```numSendsLastWeek``` is obtained by aggregating for each key of the Send table, all the sends that occur in a 7 day windown prior to the ```cutOffTime``` specified in the ```sendsReader```. - -The response variable on the other hand, is obtained by aggregating all the clicks that occur in a 1 day window following the ```cutOffTime``` specified in the ```clicksReader```: - -```scala -val numClicksTomorrow = FeatureBuilder.RealNN[Click] - .extract(click => 1.toRealNN) - .aggregate(SumRealNN) - .window(Duration.standardDays(1)) - .asResponse -``` - -Now we can also create a predictor from the combination of the clicks and sends predictors as follows: - -```scala -// .alias ensures that the resulting dataframe column name is 'ctr' -// and not the default transformed feature name -val ctr = (numClicksYday / (numSendsLastWeek + 1)).alias -``` - -In order to materialize all of these predictors and response variables, we can add them to a workflow with the appropriate readers: - -```scala -// fit the workflow to the data -val workflowModel = new OpWorkflow() - .setReader(sendsReader.leftOuterJoin(clicksReader)) - .setResultFeatures(numClicksYday, numClicksTomorrow, numSendsLastWeek, ctr) - .train() - -// materialize the features -val dataFrame = workflowModel.score() -``` - -Note that the reader for the workflow is a joined reader, obtained by joining the ```sendsReader``` with the ```clicksReader```.
