Initializer that generates the identity matrix.
Inherits From: Initializer
tf.keras.initializers.Identity(
gain=1.0
)
Only usable for generating 2D matrices.
# Standalone usage: initializer = Identity() values = initializer(shape=(2, 2))
# Usage in a Keras layer: initializer = Identity() layer = Dense(3, kernel_initializer=initializer)
| Args | |
|---|---|
gain | Multiplicative factor to apply to the identity matrix. |
cloneclone()
from_config@classmethod
from_config(
config
)
Instantiates an initializer from a configuration dictionary.
initializer = RandomUniform(-1, 1) config = initializer.get_config() initializer = RandomUniform.from_config(config)
| Args | |
|---|---|
config | A Python dictionary, the output of get_config(). |
| Returns | |
|---|---|
An Initializer instance. |
get_configget_config()
Returns the initializer's configuration as a JSON-serializable dict.
| Returns | |
|---|---|
| A JSON-serializable Python dict. |
__call____call__(
shape, dtype=None
)
Returns a tensor object initialized as specified by the initializer.
| Args | |
|---|---|
shape | Shape of the tensor. |
dtype | Optional dtype of the tensor. Only numeric or boolean dtypes are supported. If not specified, keras.backend.floatx() is used, which default to float32 unless you configured it otherwise (via keras.backend.set_floatx(float_dtype)). |
