About this Research Topic
Numerous research avenues are currently underway or anticipated for future exploration, each offering valuable opportunities for further investigation. These include the development of novel models tailored to unexplored graph structures, the enhancement of compositional aspects within existing models, addressing dynamic graphs, exploring interpretability and robustness, and more. However, given the rapid expansion of the field, attaining a comprehensive understanding of the advancements in Graph Neural Networks (GNNs) has proven to be exceedingly difficult. Therefore, we feel the urgency to bridge the above gap and have a dedicated collection of journal literatures to summarize these fast growing yet challenging topics in GNNs.
This Research Topic aims to bring together both academic and industrial researchers from different backgrounds and perspectives to above challenges. The interested topics include: 1) a thorough understanding of GNNs theories and basic concepts; 2) use of state-of-the-art algorithms to explore major recent advances in GNNs research; and 3) delve into uncharted research prospects for GNNs and examine the utilization and potential design of GNN algorithms for practical applications in the real world.
