Hyperparameter Tuning
Also written as Grid Search, Hyperparameter Optimization
Systematically trying different settings for a model to find the combination that performs best.
Think of it like
Adjusting oven temperature and timing across several batches until the bake comes out right.
Junior or senior?
Junior sounds like
Ran a search someone else set up.
Senior sounds like
Knows when the gains stopped being worth the compute bill, which is a cost judgement as much as a technical one.
Ask them
“How did you decide when to stop tuning?”
