Ziwei Zhu, Assistant Professor, Computer Science, College of Engineering and Computing (CEC), received funding for the project: “III: Small: Harnessing Interpretable Neuro-Symbolic Learning for Reliable Ranking.”
Zhu aims to forge novel neuro-symbolic learning to rank models to deliver interpretable, balanced, and robust rankings.
In this research, Zhu will introduce a neural network that transparently elucidates the entire inference process in ranking and presents a logic AutoEncoder, a type of artificial neural network for interpretable collaborative filtering rankings. He will also propose a neuro-symbolic representation learning technique to enhance model expressiveness and accuracy.
Second, he will utilize the inherent transparency in neuro-symbolic ranking algorithms to effectively enhance ranking balance for both users and items.
Further, he will propose novel strategies for leveraging and augmenting interpretable reasoning process of neuro-symbolic learning to fortify robustness against shortcut features, exposure differences, and data poisoning attacks.
Additionally, Zhu will apply proposed research innovations in two real ranking systems, organ transplantation management and research paper recommendation. He will do this to demonstrate the effectiveness of proposed technologies in real-world contexts and to ensure the proposed project has sufficient impact.
Zhu received $500,000 from the National Science Foundation for this research. Funding began in July 2025 and will end in late June 2028.
