Question 1

+2 marksOne correct option

Which of the following statements best describes the primary advantage of the SentencePiece tokenizer compared to a standard BPE implementation?

  1. A

    It is significantly faster to train because it does not need to count pairs.

  2. B

    It results in a smaller vocabulary size by always merging the shortest tokens first.

  3. C

    It is inherently language-agnostic, treating text as a raw stream of Unicode characters, which is ideal for languages without clear word delimiters like Japanese or Thai.

  4. D

    It is deterministic and always produces the same tokenization for a given string,unlike BPE which can be probabilistic.

  2. B

    The gradients calculated for each parameter.

  3. C
