Cropping1D layer

[source]

Cropping1D class

keras.layers.Cropping1D(cropping=(1, 1), **kwargs)

Cropping layer for 1D input (e.g. temporal sequence).

It crops along the time dimension (axis 1).

Examples

>>> input_shape = (2, 3, 2)
>>> 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.Cropping1D(cropping=1)(x)
>>> y
[[[2 3]]
 [[8 9]]]

Arguments

  • cropping: Int, or tuple of int (length 2), or dictionary.
    • If int: how many units should be trimmed off at the beginning and end of the cropping dimension (axis 1).
    • If tuple of 2 ints: how many units should be trimmed off at the beginning and end of the cropping dimension ((left_crop, right_crop)).

Input shape

3D tensor with shape (batch_size, axis_to_crop, features)

Output shape

3D tensor with shape (batch_size, cropped_axis, features)
