AutoTabPFNClassifier

Bases: BaseEstimator, ClassifierMixin

Automatic Post Hoc Ensemble Classifier for TabPFN models.

Attributes:

Name	Type	Description
predictor_		AutoPostHocEnsemblePredictor The predictor interface used to make predictions, see post_hoc_ensembles.pfn_phe.AutoPostHocEnsemblePredictor for more.
phe_init_args_		dict The optional initialization arguments used for the post hoc ensemble predictor.

__init__

__init__(
    max_time: int | None = 30,
    preset: Literal[
        "default", "custom_hps", "avoid_overfitting"
    ] = "default",
    ges_scoring_string: str = "roc",
    device: Literal["cpu", "cuda"] = "cpu",

    phe_init_args: dict | None = None,
)

Parameters:

Name	Type	Description	Default
max_time		int | None, default=None The maximum time to spend on fitting the post hoc ensemble.	30
preset	Literal['default', 'custom_hps', 'avoid_overfitting']	{"default", "custom_hps", "avoid_overfitting"}, default="default" The preset to use for the post hoc ensemble.	'default'
ges_scoring_string		str, default="roc" The scoring string to use for the greedy ensemble search. Allowed values are: {"accuracy", "roc" / "auroc", "f1", "log_loss"}.	'roc'
device		{"cpu", "cuda"}, default="cuda" The device to use for training and prediction.	'cpu'
random_state		int, RandomState instance or None, default=None Controls both the randomness base models and the post hoc ensembling method.	None
categorical_feature_indices	list[int] | None	list[int] or None, default=None The indices of the categorical features in the input data. Can also be passed to fit().	None
phe_init_args		dict | None, default=None The initialization arguments for the post hoc ensemble predictor. See post_hoc_ensembles.pfn_phe.AutoPostHocEnsemblePredictor for more options and all details.	None
