watex.cases.modeling.BaseModel#

class watex.cases.modeling.BaseModel(data_fn=None, df=None, **kwargs)[source]#

Base model class. The most interesting and challenging part of modeling is the tuning hyperparameters after designing a composite estimator. Getting the best params is a better way to reorginize the created pipeline {transformers +estimators} so to have a great capability of data generalization.

Parameters

  • *dataf_fn* (str) – Path to analysis data file.

  • *df* (pd.Core.DataFrame) – Dataframe of features for analysis . Must be contains of main parameters including the target name of pd.Core.series of columns of df.

  • arguments (Holds on others optionals infos in kwargs) –

  • ======================================= (================= ============) –

  • Description (Attributes Type) –

  • ======================================= –

  • estimator. (auto bool Trigger the composite) – If True a SVC-composite estimator preprocessor is given. default is False.

  • model (pipelines dict Collect your own pipeline for) – preprocessor trigging. it should be find automatically.

  • None (estimators Callable A given estimator. If) – is auto-selected as default estimator.

  • SVM – is auto-selected as default estimator.

  • test (model_score float/dict Model test score. Observe your) – model score using your compose estimator for enhancement or your own pipelines.

  • for (processor Callable Compose piplenes and estimators) – as well as the compose estimator enhancement.

  • for – default model scorage.

  • ======================================= –
