MaD Seminar: Beyond Static Memorization: Structural Inference and Generative Reasoning in Knowledge Graphs

Speaker: Joyce Whang (KAIST)

Location: 60 Fifth Avenue, Room 150

Abstract: Graph-structured data is fundamental to modern AI, driving applications from complex reasoning engines to personalized recommendation systems. At the core of these capabilities are Knowledge Graphs (KGs), which formalize real-world facts as interconnected entities and relations. While traditional KG representation learning enables the integration of this knowledge into machine learning pipelines, it relies heavily on the static memorization of fixed embeddings. This approach creates a critical bottleneck for generalizability, particularly in dynamic, open-world settings. This talk explores a paradigm shift from rote memorization toward deep structural inference. First, it introduces novel methodologies that capture the intrinsic topological relationships within KGs, enabling robust, inductive inference on entirely unseen entities and relations. Second, extending this framework to complex, hyper-relational KGs demonstrates how a purely structure-based approach achieves state-of-the-art performance on various reasoning tasks. Finally, the talk highlights the generative potential of this structural approach by proposing a novel framework that synthesizes new complex hyper-relational facts, advancing the frontier of autonomous knowledge discovery and demonstrating how structural learning effectively complements Large Language Models (LLMs).
