HyperFuse: Fast Self-Supervised Node Embeddings for Attributed Hypergraphs

Self-supervised hypergraph representation learning can produce informative node embeddings, but existing methods often require deep encoders trained for hundreds of epochs, making embedding generation costly even for hypergraphs with a few thousand nodes. This limits applications requiring embeddings for many or evolvi...

Learning the Graph and the Embedding Together: Classifier-Independent Rewiring for Heterophilic Node Classification

An affinity-guided rewiring method that estimates the graph and the node representation together and alternates, in the spirit of expectation maximisation, between training a lightweight graph neural network on the current graph and re-weighting candidate edges under a modularity objective with a pseudo-label homophily...

Building Supervision into Hebbian Plasticity through Spike Agreement

This work proposes Supervised Spike Agreement-Dependent Plasticity (Supervised SADP), a gradient-free supervised Hebbian learning algorithm in which class information is embedded directly into the Hebbian plasticity computation rather than introduced through reward modulation.
