Bi-Encoder
Model that embeds queries and passages separately so they can be compared cheaply.
Resumen
A bi-encoder encodes the query and each passage independently into vectors, and relevance is their similarity. It solves the problem that a cross-encoder must run once per candidate, which is impossible against a large collection. It exists as the half of retrieval that can be precomputed and indexed, at the cost of losing the interaction between query and passage.
