tf.keras.layers.ZeroPadding1D

Zero-padding layer for 1D input (e.g. temporal sequence).

Inherits From: Layer, Operation

tf.keras.layers.ZeroPadding1D(
    padding=1, **kwargs
)

Example:

input_shape = (2, 2, 3)
x = np.arange(np.prod(input_shape)).reshape(input_shape)
x
[[[ 0  1  2]
  [ 3  4  5]]
 [[ 6  7  8]
  [ 9 10 11]]]
y = keras.layers.ZeroPadding1D(padding=2)(x)
y
[[[ 0  0  0]
  [ 0  0  0]
  [ 0  1  2]
  [ 3  4  5]
  [ 0  0  0]
  [ 0  0  0]]
 [[ 0  0  0]
  [ 0  0  0]
  [ 6  7  8]
  [ 9 10 11]
  [ 0  0  0]
  [ 0  0  0]]]
Args
padding Int, or tuple of int (length 2), or dictionary.
  • If int: how many zeros to add at the beginning and end of the padding dimension (axis 1).
  • If tuple of 2 ints: how many zeros to add at the beginning and the end of the padding dimension ((left_pad, right_pad)).
Input shape
3D tensor with shape (batch_size, axis_to_pad, features)
Output shape
3D tensor with shape (batch_size, padded_axis, features)
Attributes
input Retrieves the input tensor(s) of a symbolic operation.

Only returns the tensor(s) corresponding to the first time the operation was called.

output Retrieves the output tensor(s) of a layer.

Only returns the tensor(s) corresponding to the first time the operation was called.

Methods

from_config

View source

@classmethod
from_config(
    config
)

Creates a layer from its config.

This method is the reverse of get_config, capable of instantiating the same layer from the config dictionary. It does not handle layer connectivity (handled by Network), nor weights (handled by set_weights).

Args
config A Python dictionary, typically the output of get_config.
Returns
A layer instance.

    *args, **kwargs
