SUDA-Muon: Structural Design Principles and Boundaries for Fully Decentralized Muon

Hengrui Zhang, Boao Kong, Jiahe Geng +1

Fully decentralized Muon is difficult because its nonlinear matrix-sign operator does not commute with linear gossip averaging. This makes decentralized Muon a structural design pr…

On the Convergence of Stochastic Gradient Descent with Perturbed Forward-Backward Passes

Boao Kong, Hengrui Zhang, Kun Yuan

We study stochastic gradient descent (SGD) for composite optimization problems with sequential operators subject to perturbations in both the forward and backward passes. Unlik…

A Diffusion-Based Method for Learning the Multi-Outcome Distribution of Medical Treatments

Yuchen Ma, Jonas Schweisthal, Hengrui Zhang +1

In medicine, treatments often influence multiple, interdependent outcomes, such as primary endpoints, complications, adverse events, or other secondary endpoints. Hence, to make op…

MUSE: Model-Agnostic Tabular Watermarking via Multi-Sample Selection

Liancheng Fang, Aiwei Liu, Henry Peng Zou +4

We introduce MUSE, a watermarking algorithm for tabular generative models. Previous approaches typically leverage DDIM invertibility to watermark tabular diffusion models, but tabu…

Diffusion-nested Auto-Regressive Synthesis of Heterogeneous Tabular Data

Hengrui Zhang, Liancheng Fang, Qitian Wu +1

Autoregressive models are predominant in natural language generation, while their application in tabular data remains underexplored. We posit that this can be attributed to two fac…
