Web13 sep. 2024 · So, we know that random search works better than grid search, but a more recent approach is Bayesian optimization (using gaussian processes). I've looked up a comparison between the two, and found nothing. I know that at Stanford's cs231n they mention only random search, but it is possible that they wanted to keep things simple.

Web25 mei 2024 · 3. I think I found a way to do it. Turns out there is a dictionary that stores the best hyperparameters values and names, to acces it you have to type the following (try it in the console first): best_hp.values. This is of course, assuming that you have already done the tuning and hyperparameter search. It's odd that I couldn't find this ...
