Web31 jan. 2024 · Both Optuna and Hyperopt are using the same optimization methods under the hood. They have: rand.suggest (Hyperopt) and samplers.random.RandomSampler (Optuna) Your standard random search over the parameters. tpe.suggest (Hyperopt) and samplers.tpe.sampler.TPESampler (Optuna) Tree of Parzen Estimators (TPE). WebIf you are allowed to choose two values with replacement (that means that sometimes both values in the subset will be same. This is the reason we used replace=False in point 1), then the following can be done: choices = [1,2,3,4] space = [hp.choice ('c1', choices), hp.choice ('c2', choices)] Then in your objective function, you can access your ...
