Integrating SPSS Model Scoring in InfoSphere Streams, Part 2: Using a generic operator

Mike Koranda (koranda@us.ibm.com), InfoSphere Streams Release Manager, IBM

Mike Koranda is a senior technical staff member in IBM's Software Group and has been working at IBM for more than 30 years. He has been working in the development of the InfoSphere Streams product for the past six years.

Summary: Part 2 of this "Integrating SPSS Model Scoring in InfoSphere Streams" series shows how to create a generic operator to execute IBM® SPSS Modeler predictive models in an InfoSphere® Streams application. It builds off the work of the non-generic operator produced in Part 1, where we wrote and used an InfoSphere Streams operator to execute a predictive model in an InfoSphere Streams application using the IBM SPSS Modeler Solution Publisher Runtime library API.

Summary

Results

This tutorial has shown how you can use a generic operator to wrap the execution of any SPSS Modeler predictive analytic (compatible with the Solution Publisher API restrictions and makes sense to execute a tuple at a time). This generic operator can be easily used by a Streams application developer to execute the predictive model against the streaming data.

Note there are other ways to execute scoring models in InfoSphere Streams through PMML and the Streams Mining toolkit. The direct wrapping technique and integration with SPSS models through the Solution Publisher interface provided here opens the scoring up to a much larger set of models than what are supported through the PMML integrations of the Mining Toolkit.
