tf.keras.ops.extract_sequences | TensorFlow v2.16.1 (original) (raw)
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]])
