class src.predictive_model.classification.custom_classification_models.NNClassifier(**kwargs)

Bases: sklearn.base.ClassifierMixin

Neural Network classifier, implements the same methods as the sklearn models to make it simple to add

fit(train_data, targets)

creates and fits the predictive_model

first the encoded data is parsed, then the predictive_model created and then trained

Parameters:

• train_data (DataFrame) – encoded training dataset
• targets (ndarray) – encoded target dataset

Return type:

None

predict(test_data)

returns predictive_model predictions

parses the encoded test dataset, then returns the predictive_model predictions

Parameters:test_data (DataFrame) – encoded test dataset Return type:ndarray Returns:predictive_model predictions

predict_proba(test_data)

returns the classification probability

parses the test dataset and returns the raw prediction probabilities of the predictive_model

Parameters:test_data (DataFrame) – encoded test dataset Return type:ndarray Returns:predictive_model prediction probabilities

reset()

placeholder to allow use with other sklearn algorithms

Return type:None
