How should an effective hybrid strategy weight CF scores as a user builds reliable interaction history?
Answer
Gradually increasing the weight of collaborative filtering scores
Effective modern culinary engines employ a dynamic weighting system to balance the strengths of CBF (good for new users/items) and CF (good for established tastes). For a new user, CBF is weighted heavily to provide initial relevant suggestions based on their explicit profile. As the user interacts more—saving, cooking, and rating recipes—their interaction history grows, making CF signals increasingly reliable. Therefore, the successful strategy involves gradually increasing the influence or weight given to Collaborative Filtering scores over time, allowing personalization to deepen and reflect the user’s evolving, community-informed culinary tastes.
