Neither, metric is a number you report through the Logger:

as I the example you gave-
hyper_parameters=[
UniformParameterRange('rep', min_value=0.1, max_value=0.9, step_size=0.05),
UniformParameterRange('coupling', min_value=0.1, max_value=0.6, step_size=0.05),
],

Thanks! What about the objective_metric_title and objective_metric_series? Are they also defined as hyperparameters? Or rather artifacts?

@<1714813627506102272:profile|CheekyDolphin49> You should probably use 'General/coupling' and 'General/rep'

Hi @<1714813627506102272:profile|CheekyDolphin49> , how are you setting the parameter in the HPO?
