QINCo implementation in CPU Faiss

Open mdouze opened this issue 1 year ago • 19 comments

Summary: This is a straightforward implementation of QINCo in CPU Faiss, with encoding and decoding capabilities (not training).

For this, we translate a simplified version of some torch classes:

  • tensors, restricted to 2D and int32 + float32

  • Linear and Embedding layer

Then the QINCoStep and QINCo can just be defined as C++ objects that are copy-constructable.

There is some plumbing required in the wrapping layers to support the integration. Pytroch tensors are converted to numpy for getting / setting them in C++.
