Uber has published technical details on its latest improvements to restaurant recommendations on Uber Eats, using real-time signals and listwise ranking models. The system prioritizes relevance and conversion metrics at inference time, optimizing for both discovery and conversion.
For infrastructure and ML ops teams, Uber's approach illustrates how large-scale e-commerce platforms optimize ranking systems under dynamic real-time constraints. The techniques transfer to other recommendation and marketplace systems under similar latency and throughput requirements.
