tf.keras.backend.ctc_batch_cost
Runs CTC loss algorithm on each batch element.
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. |
