Performs greedy decoding on the logits given in inputs.

tf.raw_ops.CTCGreedyDecoder( inputs, sequence_length, merge_repeated=False, name=None )

A note about the attribute merge_repeated: if enabled, when consecutive logits' maximum indices are the same, only the first of these is emitted. Labeling the blank '*', the sequence "A B B * B B" becomes "A B B" if merge_repeated = True and "A B B B B" if merge_repeated = False.

Regardless of the value of merge_repeated, if the maximum index of a given time and batch corresponds to the blank, index `(num_classes - 1)`

, no new element is emitted.

Args | |
---|---|

`inputs` | A `Tensor` . Must be one of the following types: `float32` , `float64` . 3-D, shape: `(max_time x batch_size x num_classes)` , the logits. |

`sequence_length` | A `Tensor` of type `int32` . A vector containing sequence lengths, size `(batch_size)` . |

`merge_repeated` | An optional `bool` . Defaults to `False` . If True, merge repeated classes in output. |

`name` | A name for the operation (optional). |

Returns | |
---|---|

A tuple of `Tensor` objects (decoded_indices, decoded_values, decoded_shape, log_probability). | |

`decoded_indices` | A `Tensor` of type `int64` . |

`decoded_values` | A `Tensor` of type `int64` . |

`decoded_shape` | A `Tensor` of type `int64` . |

`log_probability` | A `Tensor` . Has the same type as `inputs` . |
