Exploring Hierarchical Interest Representation For Meta Ads Deep Funnel Optimization

Meta announces a research area called Hierarchical Interest Representation, an upstream representation layer that learns unified embeddings for ads entities (users, advertisers, products, services) using transformer-based graph learning and multimodal knowledge enrichment to improve deep funnel ad optimization across Meta's recommendation ecosystem, including the Generative Ads Model (GEM), Andromeda, and the Adaptive Ranking Model.
