Bayesian boosting model application
Hello,
I am building prediction models using Bayesian boosting with decision trees technique. Below is the process I have set up:
Current output is set of 10 models. How do I convert those 10 models into a final tree scheme to implement in production?
Please pardon my format of question - this is my first post here.
Thanks,
I am building prediction models using Bayesian boosting with decision trees technique. Below is the process I have set up:
My question: Is there a way to extract final model (in this case decision tree) logic in either SQL or other coding version which I can use to implement?

if you are coding in java and your project license is compatible to AGPL, the easiest way would be to include RapidMiner in your project. Then you could programatically run a process to apply the trained Bayesian Boosting model on your data.
Best,
