## Which statements are true?
- [x] How well tuning works depends on the learner and the impact of the hyperparameters on that learner.
- [ ] Grid search often works better than random search.
- [x] Grid search scales exponentially with the dimension of the search space.
- [x] Grid search evaluates many points from the search space that aren't of interest.
- [x] Random search works often better due to its better exploration of the search space.
- [ ] Random search scales very well with the dimension of the search space.
- [ ] Random search as well as grid search has the problem of discretization.
