QARTA: An ML-based System for Accurate Map Services

Summary: QARTA uses ML to build an accurate, self-generated road graph with learned edge weights. It also calibrates query results by context (modality, location, time) to deliver real-time, highly accurate map services; open-source, scalable, deployed in Qatar taxis and a top food-delivery firm.
