Learner in Thingworx analytics

[trungkien2104]

Hello,

I'm a newbie in thingworx analytics but I come from data analytics. Actually, the learner is not new for me but when I configure the predictive model, I saw that I can add more leaners. So, that means the analytics module shall try to use these methods to learning the data and choose the best fit (highest ROC, RMSE, etc.) method ??? If not, what does the module do exactly ????

@trungkien2104 ,

Thank you for posting your question to the PTC Community.

You have the option of using the Learners individually or in an ensemble.

You are essentially correct, as it pertains to using an ensemble setup.

More information can be found on the ThingWorx Analytics HelpCenter - Learners and Ensemble Techniques page.

Please let me know if you have any additional questions.

Regards,

Neel

Dear Neel, @nsampat 

Thank you for your response.

That mean although we select an ensemble of learners, only a best learner is select by ordering the score. And by choosing the option (Average, Best, Elite Average, Majority Vote and Soloist), we can see the average score. Then, I think PTC can add the result of selected learner (the learner is chosen with the highest value) such as the parameter of model (for example the coefficient  in linear regression). It can help developer to tuning or validate the model with different periods of time.
