what happens when an analytics job is successful and how can the analytics model be improved

Hello,

After an Analytics job has completed successfully, a new predictive model is created.  You can create new models and access ones that were already created under the Models tab in ThingWorx Analytics Builder.  

Double clicking on a finished model will open the models results page which will give you different details about the model such as the Prediction Accuracy, RMSE, etc. 

One way you can try to improve your models is by creating several different models and editing the Learning Techniques, Ensemble Techniques, and any other settings differently for each model until you get a model with the desired accuracy.

As for your question on less data, sometimes it can be very difficult to create an accurate model if there is not enough data present.  We always recommend collecting as much data as possible and to continue adding that data to your datasets.   Usually with machine learning, the more examples you have, the more accurate the model is.

Warm Regards,

John
