tf.keras.backend.ctc_batch_cost(
y_true, y_pred, input_length, label_length
)
Arguments |
y_true
|
tensor (samples, max_string_length)
containing the truth labels.
|
y_pred
|
tensor (samples, time_steps, num_categories)
containing the prediction, or output of the softmax.
|
input_length
|
tensor (samples, 1) containing the sequence length for
each batch item in y_pred .
|
label_length
|
tensor (samples, 1) containing the sequence length for
each batch item in y_true .
|
Returns |
Tensor with shape (samples,1) containing the
CTC loss of each element.
