Working with Predictive Analytics Actions
You can call an existing predictive model from a decision entity if you map this predictive model to a predictive analytics action. Predictive models score data and help you to make decisions on the basis of quantitative logics and insights. For more information on the Predictive Analytics Plug-in, see the Apama Predictive Analytics Plug-in documentation.
Predictive Analytics Action Input and Output
A predictive analytics action can have several inputs and one output. The inputs and output of a predictive analytics action correspond to the inputs and output of the predictive model the predictive analytics action is based on. If a predictive model has more than one output, you must specify in the New Action wizard, which output you want to use in the predictive analytics action. You cannot select a descendent of a document list for a predictive analytics action output.
Specifying Predictive Analytics Action Input Values
You can specify default values for the predictive analytics action inputs when creating the predictive analytics action. For more information about the admissible data types for predictive analytics action input values, see
About Data Types for Predictive Analytics Actions.
If you do not specify default input values, you must map a parameter element to the predictive analytics action input, when using the predictive analytics action in a decision entity. For more information about mapping, see
Working with Service Actions, Specifying Service Action Input Values.
Using the Output Value from a Predictive Model
You can use the output value from a predictive model if you use the predictive analytics action that was mapped from this predictive model as:
A decision table condition value.
A decision table assignment result value.
A decision tree condition value.
A decision tree assignment result value.
An event rule assignment result value.
Executing a Predictive Model from a Decision Entity
You can execute a predictive model from a decision entity if you use the predictive analytics action that was mapped from this predictive model as:
A decision table action result.
A decision tree action result.
An event rule action result.
