Reply to comment by PHEEEEELLLLLEEEEP in Image matching within database? [P] by Clarkmilo

Well, if you're storing 1 million images in the database, it's going to take a long time to do the cosine distance for all 1 million images. FAISS will give you very roughly the 1000 nearest and you can do the cosine distance from there. My usage was anybody could enter any text phrase and search my dataset. I can't precompute the cosine distance for every query somebody might make.

What I mean is that faiss can compute knn for a variety of metrics including cosine distance. So you can just directly index by cosine distance instead of L2

Ah, I see. I didn’t know. I guess you could do it that way.
