Role of Vector Embeddings in LLMs

Large Language Models (LLMs) like GPT, BERT, and their variants heavily rely on vector embeddings to process and generate human-like text.

 

 

Here’s how embeddings power these advanced systems:

Semantic Understanding

LLMs use embeddings to represent words, sentences, and entire documents in a way that captures their semantic meaning. This allows the models to understand the context and relationships between words, leading to more accurate and relevant outputs.

Tokenization and Representation

Before feeding text into an LLM, it is broken down into smaller units called tokens. Each token is then converted into a vector embedding. These embeddings provide the model with the context it needs to generate coherent and contextually appropriate responses.

Transfer Learning

LLMs trained on large datasets generate embeddings that can be reused for various tasks, such as summarization, sentiment analysis, or question answering. This adaptability is one of the reasons embeddings are so valuable in AI.

Retrieval-Augmented Generation (RAG)

In advanced systems, embeddings are used to retrieve relevant information from external datasets during the text generation process. For example, when a chatbot answers questions, it uses embeddings to fetch the most relevant context or data before formulating its response.
