tf.raw_ops.CTCGreedyDecoder

Performs greedy decoding on the logits given in inputs.

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.

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.
blank_index An optional int. Defaults to -1.
name A name for the operation (optional).

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.
