On the Scalability of GNNs for Molecular Graphs

no code implementations17 Apr 2024 Maciej Sypetkowski, Frederik Wenkel, Farimah Poursafaei, Nia Dickson, Karush Suri, Philip Fradkin, Dominique Beaini

However, structure-based architectures such as Graph Neural Networks (GNNs) are yet to show the benefits of scale mainly due to the lower efficiency of sparse operations, large data requirements, and lack of clarity about the effectiveness of various architectures.

Temporal Graph Analysis with TGX

2 code implementations6 Feb 2024 Razieh Shirzadkhani, Shenyang Huang, Elahe Kooshafar, Reihaneh Rabbany, Farimah Poursafaei

Bridging this gap, we introduce TGX, a Python package specially designed for analysis of temporal networks that encompasses an automated pipeline for data loading, data processing, and analysis of evolving graphs.

Towards Temporal Edge Regression: A Case Study on Agriculture Trade Between Nations

1 code implementation15 Aug 2023 Lekang Jiang, Caiqi Zhang, Farimah Poursafaei, Shenyang Huang

In this paper, we explore the application of GNNs to edge regression tasks in both static and dynamic settings, focusing on predicting food and agriculture trade values between nations.
