Hyperparameter tuning with optuna
Web13 okt. 2024 · Optuna is rapidly taking over from GridSearchCV and RandomizedSearchCV as the preferred method for hyperparameter tuning. It’s a lot more efficient and can be used to tune any model, not just XGBoost models. The downside is that it’s a lot more complex to use but can quickly yield faster results. Install the packages Web10 jan. 2024 · You can find the list of hyperparameters for the LigthGBM models on the official documentation. A last crucial step is to initialize Optuna. At this point you have to indicate if you want to minimize or maximize. If you want to optimize the precision choose maximization: import optuna study = optuna.create_study(direction='maximize')
