Vocabulary
The set of unique tokens known to a language model or NLP system.
Description
In natural language processing, vocabulary refers to the set of unique tokens that a model or system recognizes. This can include words, subwords, or characters, depending on the tokenization method used. The vocabulary is typically built from the training data and has a significant impact on the model's ability to understand and generate text. The size and composition of the vocabulary can affect model performance, memory usage, and the ability to handle out-of-vocabulary words.
Examples
- 📚 Word-level vocabulary
- 🧩 Subword vocabulary (e.g., in BERT or GPT models)
- 🔤 Character-level vocabulary
