FedQueue: Queue-Aware Federated Learning for Cross-Facility HPC Training

Yijiang Li, Emon Dey, Zilinghan Li +3

Federated learning (FL) across multiple HPC facilities faces stochastic admission delays from batch schedulers that dominate wall-clock time. Synchronous FL suffers from severe str…

Scalable Heterogeneous Graph Foundation Models for Data-Driven Optimal Power Flow in Smart Grids

Massimiliano Lupo Pasini, Yijiang Li, Kibaek Kim +1

Fast and reliable optimal power flow (OPF) approximation is important for power system operation, yet heterogeneous OPF graph models are often evaluated either with architecture-sp…

Attention Sinks and Outliers in Attention Residuals

Haozheng Luo, Haoran Dai, Shaoyang Zhang +10

We propose OASIS, an outlier- and sink-aware method that stabilizes dual-normalized attention-residual architectures through explicit null routing and token-to-depth null coupling.…

LUMINA: A Grid Foundation Model for Benchmarking AC Optimal Power Flow Surrogate Learning

Hongwei Jin, Keunju Song, Zeeshan Memon +5

AC optimal power flow (ACOPF) is foundational yet computationally expensive in power grid operations, driving learning-based surrogates for large-scale grid analysis. These surroga…

Towards Systematic Generalization for Power Grid Optimization Problems

Zeeshan Memon, Yijiang Li, Hongwei Jin +2

AC Optimal Power Flow (ACOPF) and Security-Constrained Unit Commitment (SCUC) are fundamental optimization problems in power system operations. ACOPF serves as the physical backbon…
