The Building Blocks of LLMs: Vectors, Tokens and Embeddings
- Large language models (LLMs) are revolutionizing the way machines understand, generate, and manipulate human language.
- The fundamental building blocks of LLMs are vectors, tokens, and embeddings, and they play a crucial role in the models' architecture.
- Vectors are the mathematical representation of words, phrases, or even entire documents.
- Tokens are the basic units of language that carry meaning and help in understanding the structure of text.
- Word embeddings are dense vector representations that map words to a continuous vector space, where semantically similar words are closer to each other.
- Pre-trained embeddings like Word2Vec and GloVe play a crucial role in enhancing the LLMs' performance.
- LLMs employ embeddings to tackle real-world NLP tasks like machine translation, sentiment analysis, text classification, and named entity recognition.
- Contextual embeddings and subword tokenization are recent innovations in the realm of NLP.
- Understanding vectors, tokens, and embeddings is crucial for anyone venturing into the world of NLP and LLMs.
- The field of NLP is constantly evolving, and new techniques and architectures are emerging to address the challenges and limitations of traditional approaches.

How does temperature impact next token prediction in LLMs?
- The temperature parameter in LLMs affects the next token prediction.
- At a temperature of 1, the probabilities are the same as the standard softmax function.
- Increasing the temperature broadens the range of potential candidates for next token prediction.
- Decreasing the temperature boosts the model's confidence and reduces uncertainty.
