Cropping1D layer
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).
Example
>>> 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)
