Pinterest researchers introduce PinEqualizer, a system addressing the content cold-start problem across the full multi-stage retrieval and ranking funnel for both search and recommendation surfaces. The system reduces bias toward established content, enabling more accurate predictions for new content and improving fresh content exploration. Deployed at Pinterest over two years, it reports improvements in user engagement and content ecosystem health, evaluated via a scalable short-term/long-term measurement framework.
