The sample notebooks on this folder are expected to be used with Oracle Machine Learning for R.
The notebooks available in JSON format are compatible with any open-source Apache Zeppelin notebook environment.
That includes an Apache Zeppelin running on a server that can connect to an Oracle Database for using the OML4R notebook examples.
The OML4R notebooks can be used with an on-premise Oracle Database and also a Database Cloud Service (with the exception of the Autonomous Database, which runs its own Oracle Machine Learning Notebooks environment for R and Python).
