The scoring APIs are documented in the javadoc. After installation, you can invoke Scorer by submitting scoring requests to either the file system or the API.

Scoring Requests from File System

This usage provides a simple interface to test scorer functionality. (The code blocks show high-level method calls to invoke Scorer.)

// initialize
Scorer scorer = new Scorer ();
// configure
// make sure that AML file modelFile is available on file system
scorer.configure (modelFile);
// run scorer (multiple calls)
// make sure that CSV file requestFile is available on file system
scorer.score (requestFile);

Scoring Requests Using API

Teradata recommends this usage in a production environment. By preventing the I/O overheads from populating and reading request files from the file system, it improves performance. (The code blocks show high-level method calls to invoke Scorer.)

// initialize
Scorer scorer = new Scorer ();
// configure
// make sure that AML file modelFile is available on file system
Request request = scorer.configure (modelFile);
// populate data structure request
// run scorer (multiple calls)
scorer.score (request);
