Towards Causal Classification: A Comprehensive Study on Graph Neural Networks
It addresses the need for causally enhanced GNN frameworks to improve graph-based tasks like classification, which is incremental as it builds on existing models.
This study investigated the impact of causality on Graph Neural Networks (GNNs) for graph classification, testing nine models across seven datasets and finding insights into their efficiency and flexibility in different data environments.
The exploration of Graph Neural Networks (GNNs) for processing graph-structured data has expanded, particularly their potential for causal analysis due to their universal approximation capabilities. Anticipated to significantly enhance common graph-based tasks such as classification and prediction, the development of a causally enhanced GNN framework is yet to be thoroughly investigated. Addressing this shortfall, our study delves into nine benchmark graph classification models, testing their strength and versatility across seven datasets spanning three varied domains to discern the impact of causality on the predictive prowess of GNNs. This research offers a detailed assessment of these models, shedding light on their efficiency, and flexibility in different data environments, and highlighting areas needing advancement. Our findings are instrumental in furthering the understanding and practical application of GNNs in diverse datacentric fields
