Oracle supports machine learning within several tools and technologies. One of the oldest technologies that supported machine learning algorithms in database is Oracle Data Mining. This has become the core for Machine Learning for SQL which is part of Oracle Database (at no extra cost to Oracle Database users).
Oracle Analytics now supports integration with Oracle Machine Learning for SQL and can use ML models that are stored in Oracle ADW. In my blog posts I am exploring options which are available to users by using rich and powerful Oracle Autonomous Data Warehouse support for machine learning and flexible data management and visualisation of Oracle Analytics.
