Despite recent success in using the invariance principle for out-of-distribution (OOD) generalization on Euclidean data (e.g., images), studies graph are still limited. Different from images, complex nature of graphs poses unique challenges to adopting principle. In particular, distribution shifts can appear a variety forms such as attributes and structures, making it difficult identify invariance. Moreover, domain or environment partitions, which often required by OOD methods data, could be...

The graph Laplacian regularization term is usually used in semi-supervised representation learning to provide structure information for a model f(X). However, with the recent popularity of neural networks (GNNs), directly encoding A into model, i.e., f(A, X), has become more common approach. While we show that brings little-to-no benefit existing GNNs, and propose simple but non-trivial variant regularization, called Propagation-regularization (P-reg), boost performance GNN models. We formal...

Recently Graph Injection Attack (GIA) emerges as a practical attack scenario on Neural Networks (GNNs), where the adversary can merely inject few malicious nodes instead of modifying existing or edges, i.e., Modification (GMA). Although GIA has achieved promising results, little is known about why it successful and whether there any pitfall behind success. To understand power GIA, we compare with GMA find that be provably more harmful than due to its relatively high flexibility. However,...

The previously proposed cascaded inverse fast Fourier transform/fast transform (IFFT/FFT)-based point-to-multipoint (P2MP) flexible optical transceivers have the potential to equip future intensity modulation and direct detection (IMDD) access networks with excellent flexibility, adaptability, scalability upgradability. However, due their IFFT-based multi-channel aggregations, P2MP suffer high peak-to-average power ratios (PAPRs). To address technical challenge, this paper proposes a novel...

The high cost of communicating gradients is a major bottleneck for federated learning, as the bandwidth participating user devices limited. Existing gradient compression algorithms are mainly designed data centers with high-speed network and achieve $O(\sqrt{d} \log d)$ per-iteration communication at best, where $d$ size model. We propose hyper-sphere quantization (HSQ), general framework that can be configured to continuum trade-offs between efficiency accuracy. In particular, ratio end,...
