Information Routing across Batch Boundaries: Memory--Batch Tradeoffs in Lipschitz Bandits
Zicheng Lyu, Zengfeng Huang
Adaptive learning needs both a state that preserves what observations imply and opportunities to act on that state. We study this width--depth tradeoff in stochastic Lipschitz band…
Load--Reserve Wasserstein Propagation for Isotropic Diffusion Samplers
Zicheng Lyu, Zengfeng Huang
Many Wasserstein analyses of diffusion samplers control reverse-time propagation by global stability summaries of the learned drift. These summaries can hide radial geometry: equal…
TGB-Seq Benchmark: Challenging Temporal GNNs with Complex Sequential Dynamics
Lu Yi, Jie Peng, Yanping Zheng +5
Future link prediction is a fundamental challenge in various real-world dynamic systems. To address this, numerous temporal graph neural networks (temporal GNNs) and benchmark data…
Optimal Matrix Sketching over Sliding Windows
Hanyan Yin, Dongxie Wen, Jiajun Li +4
Matrix sketching, aimed at approximating a matrix consisting of vector streams of length with a smaller sketching matrix $\boldsymbo…
