Detailed Documentation¶

Operator performing CTCGreedyDecoder.

Construction¶

CTCGreedyDecoderSeqLen(
    const Output<Node>& input,
    const Output<Node>& seq_len,
    const bool merge_repeated = true,
    const element::Type& classes_index_type = element::i32,
    const element::Type& sequence_length_type = element::i32
    )

Constructs a CTCGreedyDecoderSeqLen operation.

Parameters:

input	3-D tensor of logits on which greedy decoding is performed
seq_len	1-D tensor of sequence lengths
merge_repeated	Whether to merge repeated labels
classes_index_type	Specifies the output classes_index tensor type
sequence_length_type	Specifies the output sequence_length tensor type

CTCGreedyDecoderSeqLen(
    const Output<Node>& input,
    const Output<Node>& seq_len,
    const Output<Node>& blank_index,
    const bool merge_repeated = true,
    const element::Type& classes_index_type = element::i32,
    const element::Type& sequence_length_type = element::i32
    )

Constructs a CTCGreedyDecoderSeqLen operation.

Parameters:

input	3-D tensor of logits on which greedy decoding is performed
seq_len	1-D tensor of sequence lengths
blank_index	Scalar or 1-D tensor with 1 element used to mark a blank index
merge_repeated	Whether to merge repeated labels
classes_index_type	Specifies the output classes_index tensor type
sequence_length_type	Specifies the output sequence_length tensor type

Methods¶

virtual void validate_and_infer_types()

Verifies that attributes and inputs are consistent and computes output shapes and element types. Must be implemented by concrete child classes so that it can be run any number of times.

Throws if the node is invalid.

bool get_merge_repeated() const

Get merge_repeated attribute.

Returns:

Current value of merge_repeated attribute

const element::Type& get_classes_index_type() const

Get classes_index_type attribute.

Returns:

Current value of classes_index_type attribute

void set_classes_index_type(const element::Type& classes_index_type)

Set classes_index_type attribute.

Parameters:

classes_index_type

Type of classes_index

const element::Type& get_sequence_length_type() const

Get sequence_length_type attribute.

Returns:

Current value of sequence_length_type attribute

void set_sequence_length_type(const element::Type& sequence_length_type)

Set sequence_length_type attribute.

Parameters:

sequence_length_type

Type of sequence length
