Thiviyan Thanapalasingam
I am a Research Scientist at Sony AI, working on accelerating scientific discoveries through AI.
PhD candidate at the University of Amsterdam, advised by Paul Groth and Peter Bloem.
My research interests include Neurosymbolic Learning and Reasoning, and AI for Scientific Discovery.
News
Together with Kareem Ahmed, I am serving as an Area Chair for the Neurosymbolic Generative Models special track at the NeSy 2025 Conference. You can find the Call for Papers for our Special Track here.
I have joined Sony AI as a Research Scientist! My work focuses on advancing AI-driven methods to accelerate scientific discovery, exploring new ways to uncover patterns in complex scientific domains.
I began a Research Internship at Sony AI in Barcelona 🇪🇸, contributing to cutting-edge projects at the intersection of NeSy and science.
A new preprint on GRAPES: Learning to Sample Graphs for Scalable Graph Neural Networks is now available on arXiv. GRAPES is a GFlowNet-based sampling approach that selects crucial nodes for a given downstream task, enabling GNNs to scale to large graphs.
A new preprint on IntelliGraphs: Datasets for Benchmarking Knowledge Graph Generation is now available on arXiv.
Last week, I attended the NeSy 2023 workshop which was hosted at the beautiful Certosa di Pontignano in Siena, Italy 🇮🇹. It was a perfect blend of networking and diving deeper into the fascinating world of NeSy research.
