Specify Oracle Machine Learning Model Settings for an R Model

This topic applies only to Oracle on-premises.

The machine learning model settings for an R language model determine the characteristics of the model and are specified in the model settings table.

You can build a machine learning model in the R language by specifying R as the value of the ALGO_EXTENSIBLE_LANG setting in the model settings table. You can create a model by combining in the settings table generic settings that do not require an algorithm, such as ODMS_PARTITION_COLUMNS and ODMS_SAMPLING. You can also specify the following settings, which are exclusive to an R machine learning model.

• ALGO_EXTENSIBLE_LANG

• RALG_BUILD_FUNCTION

• RALG_BUILD_PARAMETER

• RALG_DETAILS_FORMAT

• RALG_DETAILS_FUNCTION

• RALG_SCORE_FUNCTION

• RALG_WEIGHT_FUNCTION
