Circular Dependency Fixes when Bootstrapping a Golden Set
Radu Gheorghe, Rafał Kuć
For a golden set, you need queries. Even if you have them, you can’t judge all docs for each query. Only the top N. How do we rank the top N? See the circular dependency? We’ll talk about ways to untangle it: lexical search, significant terms, training an embedder from scratch, etc. By iteratively refining data and queries, we'll get there.
