Hyperspherical Graph Representation Learning with Adaptive Alignment and Uniformity
Analysis
Key Takeaways
- •Proposes HyperGRL, a novel framework for graph representation learning.
- •Employs hyperspherical embeddings with neighbor-mean alignment and uniformity objectives.
- •Introduces an entropy-guided adaptive balancing mechanism for stable training.
- •Achieves superior performance on node classification, clustering, and link prediction tasks.
- •Avoids complex architectures, negative sampling, and sensitive hyperparameter tuning.
“HyperGRL delivers superior representation quality and generalization across diverse graph structures, achieving average improvements of 1.49%, 0.86%, and 0.74% over the strongest existing methods, respectively.”
