Applying deep learning to Related Pins
One of the most popular ways people find ideas on Pinterest is through Related Pins, an item-to-item recommendations system that uses collaborative filtering. Previously, candidates were generated using board co-occurrence, signals from all the boards a Pin is saved to. Now, for the first time, we’re applying deep learning to make Related Pins even more relevant. Ultimately, we developed a scalable system that evolves with our product and people’s interests, so we can surface the most relevant recommendations through Related Pins.
