Session: Architecting AI-Driven Personalized Discovery with Generative Models
Modern search and recommendation systems must interpret ambiguous user intent and translate it into structured, actionable signals at scale. This talk explores how Generative AI and ML are used to power personalized discovery in large-scale consumer platforms. We will examine how high-level queries are decomposed into semantic tokens through LLM-driven intent modeling, normalization, and enrichment, and how these signals are integrated into retrieval, ranking, and diversification pipelines. The session covers system design considerations across token generation, feature fusion, ranking models, and dynamic content generation, along with experimentation frameworks and causal measurement strategies used to evaluate impact. Attendees will gain a systems-level understanding of how GenAI augments traditional search and recommendation architectures to drive measurable improvements in relevance, engagement, and conversion.
