Researchers have developed a deep-learning system to optimize retrieval in e-commerce platforms like Pinterest. This system aims to trigger shopping suggestions only when beneficial, reducing unnecessary distractions for users. By employing a multi-task model trained with causal inference techniques, the system learns personalized policies to predict and improve the outcomes of triggering shopping candidates. The implementation at Pinterest resulted in an 85% reduction in shopping triggers while maintaining key shopping sessions, leading to a 0.26% increase in total sessions and a 1.10% rise in Pin saves, alongside significant infrastructure savings.
