The default Max Fields value is 25, which is not enough for time series model. How to set this parameter when creating time series model?

Let's say, my dataset has 15 fields, including one entity_id filed and one temporal field. When I set lookback to 16, UseGoladHistory to false, then how to set the Max Fields?

Apologies, I misunderstood your request.

In this case I think the Help Center page Time Series Predictions will have some relevant information, look specifically at the history-pivoted data mentioned.

 

Kind regards

Hi @zhuwenxi 

 

If you are using Builder, when creating the model under Advanced Model Configuration tab, you do have a field for Max Fields.

If using the CreateJob() service from TrainingThing , you do have a parameter 

maxAllowedFields in the service. 
 
Hope this helps

When building a time series model, Analytics will generate many fields, the default MaxFields 25 is not enough ,and will ignore many fields. I just want to know is there a way to evaluate how many fields will be used. What I do now is set MaxFields to a bigger enough value.
