Explainable AI
Sep 2022 - Present
I work on the explainability of Graph Neural Networks (GNNs), focusing on post hoc explainability methods and reasoning systems for Knowledge Graph Embeddings (KGEs). My research aims to bridge explainability techniques developed for GNNs with the embedding and inference mechanisms used in knowledge graphs.
I explore these methods across various downstream tasks, including graph classification, node classification, link prediction, entity resolution, and question answering.
