The era of large language models (LLMs) is here, bringing with it rapidly evolving libraries like ChromaDB that help augment LLM applications. You’ve most likely heard of chatbots like OpenAI’s ChatGPT, and perhaps you’ve even experienced their remarkable ability to reason about natural language processing (NLP) problems.
Modern LLMs, while imperfect, can accurately solve a wide range of problems and provide correct answers to many questions. But, due to the limits of their training and the number of text tokens they can process, LLMs aren’t a silver bullet for all tasks.
You wouldn’t expect an LLM to provide relevant responses about topics that don’t appear in their training data. For example, if you asked ChatGPT to summarize information in confidential company documents, then you’d be out of luck. You could show some of these documents to ChatGPT, but there’s a limited number of documents that you can upload before you exceed ChatGPT’s maximum number of tokens. How would you select documents to show ChatGPT?
To address these shortcomings and scale your LLM applications, one great option is to use a vector database like ChromaDB. A vector database allows you to store encoded unstructured objects, like text, as lists of numbers that you can compare to one another. You can, for example, find a collection of documents relevant to a question that you want an LLM to answer.
In this video course, you’ll learn about:
- Representing unstructured objects with vectors
- Using word and text embeddings in Python
- Harnessing the power of vector databases
- Encoding and querying over documents with ChromaDB
- Providing context to LLMs like ChatGPT with ChromaDB
After watching, you’ll have the foundational knowledge to use ChromaDB in your NLP or LLM applications. Before watching, you should be comfortable with the basics of Python and high school math.
