ZeroPadding1D
classkeras.layers.ZeroPadding1D(padding=1, **kwargs)
Zero-padding layer for 1D input (e.g. temporal sequence).
Examples
>>> 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]]]
Arguments
(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)
