Method Detail

maskSequence

org.nd4j.common.primitives.Pair<List<String>,boolean[]> maskSequence(List<String> input,
                                                                           String maskToken,
                                                                           List<String> vocabWords)

Parameters:

input - Input sequence of tokens

maskToken - Token to use for masking - usually something like "[MASK]"

vocabWords - Vocabulary, as a list

Returns:

Pair: The new input tokens (after masking out), along with a boolean[] for whether the token is masked or not (same length as number of tokens). boolean[i] is true if token i was masked.
