LLMs – Part 1: Tokenization and Embeddings (vasupasupuleti.substack.com)

Recent discussions in the field of AI and machine learning have highlighted the foundational processes of tokenization and embeddings, crucial components for large language models (LLMs). Tokenization involves breaking down text into manageable units, or tokens, which can range from words to subwords, allowing models to interpret varied language constructs more effectively. This process significantly impacts how information is parsed and understood by LLMs, influencing their performance across diverse linguistic tasks. Embeddings, on the other hand, serve as the numerical representation of these tokens in a continuous vector space. This allows LLMs to capture semantic relationships between words, facilitating nuanced understanding and generation of human-like text. The significance of these techniques lies in their ability to enhance the model's comprehension, enabling applications in natural language processing such as improved sentiment analysis, conversational agents, and machine translation. As researchers delve into optimizing tokenization and embedding strategies, the implications for model efficiency, accuracy, and contextual understanding become increasingly vital for the advancement of AI-driven solutions.
