tf.keras.losses.CTC
CTC (Connectionist Temporal Classification) loss.
Inherits From: Loss
tf.keras.losses.CTC(
reduction='sum_over_batch_size', name='ctc'
)
| Args | |
|---|---|
y_true | A tensor of shape (batch_size, target_max_length) containing the true labels in integer format. 0 always represents the blank/mask index and should not be used for classes. |
y_pred | A tensor of shape (batch_size, output_max_length, num_classes) containing logits (the output of your model). They should not be normalized via softmax. |
