tf.compat.v1.keras.layers.Softmax

tf.keras.layers.Softmax(
    axis=-1, **kwargs
)

Example without mask:

inp = np.asarray([1., 2., 1.])
layer = tf.keras.layers.Softmax()
layer(inp).numpy()
array([0.21194157, 0.5761169 , 0.21194157], dtype=float32)
mask = np.asarray([True, False, True], dtype=bool)
layer(inp, mask).numpy()
array([0.5, 0. , 0.5], dtype=float32)

Input shape:

Arbitrary. Use the keyword argument input_shape (tuple of integers, does not include the samples axis) when using this layer as the first layer in a model.

Output shape:

Same shape as the input.

Call arguments:

• inputs: The inputs, or logits to the softmax layer.
• mask: A boolean mask of the same shape as inputs. Defaults to None.
