Predefined UDFs for ML Preprocessing
The predefined UDFs for ML preprocessing are a collection of user defined functions available for users to add to their database to assist with machine learning data preprocessing before feeding the data into machine learning models.
An Actian public git repository holds the functions definition (SQL) files:
https://github.com/ActianCorp/Ingres_Vector_pre-defined_UDFs/tree/1.0
There are two utilities available to assist with the UDFs:
This download utility is available for database administrators to download the functions definition files from the git repository. This script has options to target specific versions of the functions, but the default setting is to download a specific version that has been tested with the running database.
This import utility is available for database users to make use of the functions definition files and create and update the functions in their database.
