Optimizing Quantum Key Distribution Network Performance using Graph Neural Networks

A new framework named InfGraND has been introduced to facilitate Influence-guided Knowledge Distillation from Graph Neural Networks (GNNs) to Multi-Layer Perceptrons (MLPs). This framework aims to enhance the efficiency of MLPs by prioritizing structurally influential nodes in the graph, addressing challenges faced by traditional GNNs in low-latency and resource-constrained environments.

A new framework named GADPN has been proposed to enhance Graph Neural Networks (GNNs) by refining graph topology through low-rank denoising and generalized structural perturbation, addressing issues of noise and missing links in graph-structured data.

Recent research highlights the potential of Subgraph Graph Neural Networks (GNNs) for node classification, addressing the limitations of traditional node-centric approaches that suffer from high computational costs and scalability issues. The proposed SubGND framework aims to enhance efficiency while maintaining classification accuracy through innovative techniques like differentiated zero-padding and Ego-Alter subgraph representation.

A novel framework named Directed Homophily-aware Graph Neural Network (DHGNN) has been introduced to address the challenges faced by traditional Graph Neural Networks (GNNs) in generalizing to heterophilic neighborhoods and in processing directed graphs. DHGNN incorporates homophily-aware and direction-sensitive components, utilizing a resettable gating mechanism and a noise-tolerant fusion module to enhance performance.
