CatBoost Model

class qsar.models.catboost.CatboostModel(max_iter: int = 100000, random_state: int = 0, params=None)

Bases: BaselineModel

A class used to represent a CatboostModel which inherits from the Model class. This class is specific for handling CatBoost Regressor models.

optimize_hyperparameters(trial: Trial, df: DataFrame) → float

Optimizes the hyperparameters of the CatBoost Regressor model using a trial from Optuna.

Parameters:

• trial (Trial) – the trial for hyperparameter optimization

• df (pd.DataFrame) – the dataframe used for training the model

Returns:

the cross validation score of the model

Return type:

float
