Hi,
We’ve implemented Sparse / Dense retrieval in Pinecone and it seems to work well for our specific use-case. However, there is one issue we’re not sure how to deal with: the similarity metrics. We consistently get dotproduct similarity scores above 1. Assuming this is indeed measuring cosine similarity - what is going on here? Supposedly the max cosine similarty metric = 1.
We’re looking into implementing an observability feature but we need to learn how to interpret these sparse / dense values.
Any help greatly appreciated.
