2
What is the primary drawback of naive Word-Level Tokenization (e.g., splitting on spaces)?
3
What is the primary drawback of purely Character-Level Tokenization?
4
How does Byte-Pair Encoding (BPE, Sennrich et al., 2016) construct its subword vocabulary?
5
How does WordPiece tokenization (used in BERT) select token merges differently from BPE?
6
What prefix does BERT's WordPiece tokenizer attach to denote that a subword is a continuation of a word rather than the start?
7
How does SentencePiece (Kudo & Richardson, 2018) treat whitespace, making it language-independent?
8
What is Byte-level BPE (used in GPT-2, GPT-3, GPT-4, and LLaMA)?
9
What is the typical vocabulary size chosen for modern Large Language Models (e.g., LLaMA, Mistral, GPT-4)?
10
What is 'Token Healing' (e.g., in Guidance or text generation engines)?
