  • Show HN: A fast HNSW implementation in Rust

    How does this compare to hsnwlib - is it faster? https://github.com/nmslib/hnswlib
  • Show HN: Moodflix – a movie recommendation engine based on your mood
    1 project | news.ycombinator.com | 9 Nov 2023
    Last week I released Moodflix (https://moodflix.streamlit.app), a movie recommendation engine based to find movies based on your mood.

    Moodflix was created on top of a movie dataset of 10k movies from The Movie Database. I vectorised the films using Hugging Face's T5 model (https://huggingface.co/docs/transformers/model_doc/t5) using the film's plot synopsis, genres and languages. Then I indexed the vectors using hnswlib (https://github.com/nmslib/hnswlib). LLMs can understand a movie's plot pretty well and distill the similarities between a user's query (mood) to the movie's plot and genres.

    I have got feedback from close friends around linking movies to other review sites like IMDB or Rotten Tomatoes, linking movies to sites to stream the movie and adding movie posters. I would also love to hear from the community what things you like, what you want to see and what things you consider can be improved.

    Actually the "ef" is not epsilon. It is a parameter of the HNSW index: https://github.com/nmslib/hnswlib/blob/master/ALGO_PARAMS.md...

    If you want to go larger you could still use some simple setup in conjunction with faiss, annoy or hnsw.

    Many vector databases are using Hnswlib and that is a supported vector index alongside Faiss and Annoy.
  • Faiss: A library for efficient similarity search

    hnswlib (https://github.com/nmslib/hnswlib) is a strong alternative to faiss that I have enjoyed using for multiple projects. It is simple and has great performance on CPU.

    After working through several projects that utilized local hnswlib and different databases for text and vector persistence, I integrated hnswlib with sqlite to create an embedded vector search engine that can easily scale up to millions of embeddings. For self-hosted situations of under 10M embeddings and less than insane throughput I think this combo is hard to beat.

  • Storing OpenAI embeddings in Postgres with pgvector

    Used it to index 40M text snippets in the legal domain. Allows incremental adding.

    I love how it just works. You know, doesn’t ANNOY me or makes a FAISS. ;-)

    3000 texts doesn't sound like to many, so may be a brute force cos calculation to find the most similar vector would work. If that's taking too much time, may be look at KNN or ANN modules to speed up finding the most similar vector. I use hsnwlib in knn mode for this. SOrt through about 350,000 vectors in about 30-50 msec.

    hnswlib is in cpp and has python bindings (you should be able to make your own for other languages).
