A SageMakerEstimator that runs a Linear Learner training job in "multiclass classifier" mode in SageMaker and returns a SageMakerModel that can be used to transform a DataFrame using the hosted Linear Learner model. The Linear Learner Binary Classifier is useful for classifying examples into one of two classes.
Amazon SageMaker Linear Learner trains on RecordIO-encoded Amazon Record protobuf data. SageMaker Spark writes a DataFrame to S3 by selecting a column of Vectors named "features" and, if present, a column of Doubles named "label". These names are configurable by passing a map with entries in trainingSparkDataFormatOptions with key "labelColumnName" or "featuresColumnName", with values corresponding to the desired label and features columns.
Inferences made against an Endpoint hosting a Linear Learner Binary classifier model contain a "score" field and a "predicted_label" field, both appended to the input DataFrame as Doubles.
