DESCRIPTION:Cold start is a critical bottleneck for marketplaces: new items
  lack behavioral signals and reviews\, so ranking models under-expose them
 \, delaying the very signals needed to rank them well. This talk shares pr
 actical solutions developed at scale for a travel marketplace\, including 
 guaranteed exposure at key positions\, efficient real-time re-ranking\, an
 d targeted boosting for unactivated items. Attendees will learn how experi
 ment-driven iteration shaped a robust system that accelerates early tracti
 on for new items without sacrificing overall marketplace health.
