Return user data from bayesopt

2 次查看(过去 30 天)
I am using bayesopt to minimize an objective function. Besides the minimum value of the function, I would like to have addintional information generated inside it when the minimization is completed. A simplified problem would be:
x = optimizableVariable('x',[0,10]);
f_eval = @(x)fun(x);
results = bayesopt(f_eval,x);
function [fitness,userData] = fun(x)
fitness = x.x^2 - 2*x.x + 1;
userData = x.x^3;
end
So I would like to see inside results the value of userData for which x results in a minimum fitness function.
Any idea how to do it?
Thanks!! Pablo

The syntax for writing an objective function that outputs extra user data is described here. You can see an example here.
Notice that results contains a UserDataTrace property.
