In-Database Algorithms Supported by OML4R

7.1.1 In-Database Algorithms Supported by OML4R

The functions in the OREdm package provide access to the in-database machine learning functionality of Oracle Database. You use these functions to build in-database models in the database.

The following table lists the OML4R functions that build in-database models and the corresponding in-database algorithms and functions.
