Creates ngrams from ragged string data.
This op accepts a ragged tensor with 1 ragged dimension containing only
strings and outputs a ragged tensor with 1 ragged dimension containing ngrams
of that string, joined along the innermost axis.

StringNGrams<T>
create
(Scope scope, Operand<String> data, Operand<T> dataSplits, String separator, List<Long> ngramWidths, String leftPad, String rightPad, Long padWidth, Boolean preserveShortSequences)
Factory method to create a class wrapping a new StringNGrams operation.
Parameters
| scope |
current scope |
| data |
The values tensor of the ragged string tensor to make ngrams out of. Must be a
1D string tensor. |
| dataSplits |
The splits tensor of the ragged string tensor to make ngrams out of. |
| separator |
The string to append between elements of the token. Use "" for no separator. |
| ngramWidths |
The sizes of the ngrams to create. |
| leftPad |
The string to use to pad the left side of the ngram sequence. Only used if
pad_width != 0. |
| rightPad |
The string to use to pad the right side of the ngram sequence. Only used if
pad_width != 0. |
| padWidth |
The number of padding elements to add to each side of each
sequence. Note that padding will never be greater than 'ngram_widths'-1
regardless of this value. If `pad_width=-1`, then add `max(ngram_widths)-1`
elements. |
Returns
- a new instance of StringNGrams
public
Output<String>
ngrams
()
The values tensor of the output ngrams ragged tensor.
public
Output<T>
ngramsSplits
()
The splits tensor of the output ngrams ragged tensor.
