Optimal hyper-parameter searching

WebThe limitations of grid search are pretty straightforward: Grid search does not scale well. There is a huge number of combinations we end up testing for just a few parameters. For example, if we have 4 parameters, and we want to test 10 values for each parameter, there are : \(10 \times 10 \times 10 \times 10 = 10'000\) combinations possible. WebYou are looking for Hyper-Parameter tuning. In parameter tuning we pass a dictionary containing a list of possible values for you classifier, then depending on the method that you choose (i.e. GridSearchCV, RandomSearch, etc.) the best possible parameters are returned. You can read more about it here. As example :
