Hierarchical Attention Models for Multi-Relational Graphs

1 code implementation14 Apr 2024 Roshni G. Iyer, Wei Wang, Yizhou Sun

BR-GCN models use bi-level attention to learn node embeddings through (1) node-level attention, and (2) relation-level attention.

Bi-Level Attention Graph Neural Networks

1 code implementation23 Apr 2023 Roshni G. Iyer, Wei Wang, Yizhou Sun

Recent graph neural networks (GNNs) with the attention mechanism have historically been limited to small-scale homogeneous graphs (HoGs).

Dual-Geometric Space Embedding Model for Two-View Knowledge Graphs

1 code implementation19 Sep 2022 Roshni G. Iyer, Yunsheng Bai, Wei Wang, Yizhou Sun

For works that seek to put both views of the KG together, the instance and ontology views are assumed to belong to the same geometric space, such as all nodes embedded in the same Euclidean space or non-Euclidean product space, an assumption no longer reasonable for two-view KGs where different portions of the graph exhibit different structures.

Question-Answer Sentence Graph for Joint Modeling Answer Selection

no code implementations16 Feb 2022 Roshni G. Iyer, Thuy Vu, Alessandro Moschitti, Yizhou Sun

This research studies graph-based approaches for Answer Sentence Selection (AS2), an essential component for retrieval-based Question Answering (QA) systems.

Software Language Comprehension using a Program-Derived Semantics Graph

no code implementations NeurIPS Workshop CAP 2020 Roshni G. Iyer, Yizhou Sun, Wei Wang, Justin Gottschlich

To continue to advance this research, we present the program-derived semantics graph, a new graphical structure to capture semantics of code.
