Oracle Analytics Server (OAS) enables you to use custom scripts to train machine learning (ML) models. This capability isn't enabled by default, so you must do it manually. The process takes approximately 15 minutes. That's time well spent, because it helps expand your data exploration possibilities, increasing your insights and the value you can derive from your data. This blog lists the steps to enable custom scripts, and you can also check the Oracle Help Center for more details about machine learning in OAS.
