16. A data analyst has trained an Extreme Gradient Boosting Algorithm using the default hyperparameters. The model obtained an accuracy of 80 percent. The analyst was advised that if she does hyperparameter tuning, she can improve the perfomance of the model. Which among the following methods can the analyst use. - i. Bayesian search- ii. Grid search- iii. Randomized searchii. onlyiii. onlyii. and iii. onlyi., ii., and iii.i. and ii. onlyi. and iii. onlyi. only
