Core wrapper.
This file contains the Keras model wrapper around an Yggdrasil model/learner. While it can be used directly, the helper functions in keras.py / wrapper_pre_generated.py should be preferred as they explicit more directly the learner specific hyper-parameters.
Usage example:
# Indirect usage
import tensorflow_decision_forests as tfdf
model = tfdf.keras.RandomForestModel()
train_ds = tfdf.keras.pd_dataframe_to_tf_dataset(...)
model.fit(train_ds)
# Direct usage
import tensorflow_decision_forests as tfdf
model = tfdf.keras.CoreModel(learner="RANDOM_FOREST")
train_ds = tfdf.keras.pd_dataframe_to_tf_dataset(...)
model.fit(train_ds)
See "CoreModel" for more details
