Predict Using Model

Step Details
Introduced in Version	9.0.0
Last Modified in Version	9.0.0
Location	Integration > Amazon AWS > Machine Learning

The Predict Using Model step is used to use a specified model to predict an outcome based on how the specified model was trained.

Prerequisites

This step requires the Amazon AWS Module to be installed before it will be available in the toolbox, and an active AWS account. The Amazon WebServices Settings must also be configured.
A dependency must be created after installing the module in order for the the steps to be properly used.

AWS Machine Learning is only available to preexisting customers that previously had access to this process. If access to the Machine Learning process is unavailable, consider using Amazon SageMaker as an alternative.
