Regularizer that encourages input vectors to be orthogonal to each other.
Inherits From: Regularizer
tf.keras.regularizers.OrthogonalRegularizer(
factor=0.01, mode='rows'
)
It can be applied to either the rows of a matrix (mode="rows"
) or its
columns (mode="columns"
). When applied to a Dense
kernel of shape
(input_dim, units)
, rows mode will seek to make the feature vectors
(i.e. the basis of the output space) orthogonal to each other.
Example:
regularizer = tf.keras.regularizers.OrthogonalRegularizer(factor=0.01)
layer = tf.keras.layers.Dense(units=4, kernel_regularizer=regularizer)
Methods
from_config
@classmethod
from_config( config )
Creates a regularizer from its config.
This method is the reverse of get_config
,
capable of instantiating the same regularizer from the config
dictionary.
This method is used by Keras model_to_estimator
, saving and
loading models to HDF5 formats, Keras model cloning, some visualization
utilities, and exporting models to and from JSON.
Args | |
---|---|
config
|
A Python dictionary, typically the output of get_config. |
Returns | |
---|---|
A regularizer instance. |
get_config
get_config()
Returns the config of the regularizer.
An regularizer config is a Python dictionary (serializable) containing all configuration parameters of the regularizer. The same regularizer can be reinstantiated later (without any saved state) from this configuration.
This method is optional if you are just training and executing models, exporting to and from SavedModels, or using weight checkpoints.
This method is required for Keras model_to_estimator
, saving and
loading models to HDF5 formats, Keras model cloning, some visualization
utilities, and exporting models to and from JSON.

__call__
__call__(
inputs
)
Compute a regularization penalty from an input tensor.
