Bayesian Optimization factor range setting

matteo_patelmo — Thu, 13 Nov 2025 15:26:30 GMT

I would like to use Bayesian Optimization starting from 2 data points. The factors for these data points (historical data) span only a very limited range, but I would like to expand the exploration to a wider range for some of the factors.

It seems that BO by default is stuck with the initial explored range. Is there a way to set the range to be explored, so that I can go outside the initially explored hypercube?

thanks
Matteo

Hi @matteo_patelmo,

The range that BayesOpt is set to explore is agnostic of the actual entries you've used - you just need to go on each column for each factor and set 'Coding' to say the limits that you want explored (see screenshot below).

Thanks!

Ben

You can also modify the factor range using the Profilers on the Batch Selection tab.

Hi @matteo_patelmo,

JMP DoE and Bayesian Optimization platforms use similar metadata from the datatable to make the analysis or design creation easier: Factors column properties (Design Role, Coding, Factor Changes, Mixture, etc...), Response Limits, and Constraint script added to the datatable as soon as you have specified any constraint and created the DoE datatable.

The Bayesian Optimization platform use many of these metadata to work.
You can see some explanations here

Hope this complementary answer may help you,
