Show HN: A GPU-accelerated binary vector index

  • Does it beat hnswlib? Also, it would be nice to see code examples (C++) without the API.

  • When and how would one use binary vectors for encoding in ML? Do you have to make your model work natively with binary vectors or is there a translation step between float and binary vectors to make it compatible?

  • Great work. Can you elaborate on how the radix selection works and how to get that working with float's and inner product distance? I just quickly checked the code, I'm not familiar with radix selection, but really interested in making extremely fast GPU indices.
