What's New in the Oracle Data Mining APIs?

This section describes new features in the Oracle Data Mining APIs. It includes the following sections:

• Oracle Data Mining 11g Release 2 (11.2.0.3) API New Features

• Oracle Data Mining 11g Release 2 (11.2.0.1) API New Features

Oracle Data Mining 11g Release 2 (11.2.0.3) API New Features

The Oracle Data Mining Java API is deprecated in this release.

Oracle Data Mining 11g Release 2 (11.2.0.1) API New Features

This section lists the changes that have been introduced in the Oracle Data Mining 11.2 PL/SQL API:

• Support for Native Transactional Data with Association Rules

  In Oracle Data Mining 11g Release 2 (11.2), you can build association rules models without first transforming the transactional data.

  See:

  "Market Basket Data"

• SVM Class Weights Specified with CLAS_WEIGHTS_TABLE_NAME

  Previously SVM class weights were specified in the priors table (CLAS_PRIORS_TABLE_NAME setting). Now SVM class weights and GLM class weights are both specified in a class weights table (CLAS_WEIGHTS_TABLE_NAME setting)

  See:

  DBMS_DATA_MINING setting CLAS_WEIGHTS_TABLE_NAME in Oracle Database PL/SQL Packages and Types Reference

• FORCE argument to DROP_MODEL

  You can now force a drop model operation even if a serious system error has interrupted the model build process.

  See:

  DBMS_DATA_MINING.DROP_MODEL procedure in Oracle Database PL/SQL Packages and Types Reference

• GET_MODEL_DETAILS_SVM has new REVERSE_COEF parameter

  To preserve model transparency, the GET_MODEL_DETAILS functions automatically reverse the transformations generated by ADP during the model build. You can obtain the transformed attribute coefficients used internally by an SVM model by setting the new reverse_coef parameter to 1. This causes the coefficients and bias to be returned with the normalization shifts and scales applied by ADP.

  See:

  DBMS_DATA_MINING.GET_MODEL_DETAILS_SVM in Oracle Database PL/SQL Packages and Types Reference
