View source on GitHub

Runs CTC loss algorithm on each batch element.

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.
