Researchers have developed a novel multi-objective ranking system for live-streaming recommendation platforms to address challenges of sparse and delayed user behaviors. The system incorporates a delayed window approach for extended feedback collection and a multi-model architecture that combines fresh and delayed signals. Additionally, a segment-aware targeting module optimizes ranking scores based on user lifecycle stages, and a Multi-gate Mixture-of-Experts (MMoE) integration reduces model parameters while jointly modeling correlated targets. Online A/B testing showed significant improvements in Daily Active Viewers (DAV) and Average Revenue Per User (ARPU), with specific gains for newer viewers and overall DAV increases from the MMoE enhancement.
