Expands the dimension of last axis into sequences of sequence_length.
tf.keras.ops.extract_sequences(
x, sequence_length, sequence_stride
)
Slides a window of size sequence_length over the last axis of the input
with a stride of sequence_stride, replacing the last axis with
[num_sequences, sequence_length] sequences.
If the dimension along the last axis is N, the number of sequences can be computed by:
num_sequences = 1 + (N - sequence_length) // sequence_stride
Args | |
|---|---|
x
|
Input tensor. |
sequence_length
|
An integer representing the sequences length. |
sequence_stride
|
An integer representing the sequences hop size. |
Returns | |
|---|---|
| A tensor of sequences with shape [..., num_sequences, sequence_length]. |
Example:
x = keras.ops.convert_to_tensor([1, 2, 3, 4, 5, 6])extract_sequences(x, 3, 2)array([[1, 2, 3],[3, 4, 5]])
