I am using quite a number of DM_NESTED_BINARY_DOUBLES objects in my data table. I do know that the error occurs right away, within one second of calling CREATE_MODEL. It could be anything ranging from formatting and exporting the data to the R procedure, to some internal bug in the R procedure, to a whole host of other things. 'Feature not supported' is quite vague and there is not much information on it. I am getting a strange error when running the CREATE_MODEL procedure. I have been running data mining algorithms in Oracle 19c (primarily using SVM and random forests) and have just upgraded to 21c and wanted to give XGBoost a try. Oracle has re-used and integrated the open source code.Īs such, XGBoost is perhaps somewhat different under-the-hood, than other Oracle data mining algorithms. (I think there is an R module behind the scenes). Oracle has implemented it on Oracle 21c by way of an external module. XGBoost is a popular and award winning data mining algorithm. 1.7K Training / Learning / Certification.165.3K Java EE (Java Enterprise Edition).7.9K Oracle Database Express Edition (XE).
