Maximal Inequalities for Separately Exchangeable Empirical Processes

2025-02-17 · Harold D. Chiang

This paper derives new maximal inequalities for empirical processes associated with separately exchangeable random arrays. For fixed index dimension $K\ge 1$, we establish a global maximal inequality bounding the $q$-th moment ($q\in[1,\infty)$) of the supremum of these processes. We also obtain a refined local maximal inequality controlling the first absolute moment of the supremum. Both results are proved for a general pointwise measurable function class. Our approach uses a new technique partitioning the index set into transversal groups, decoupling dependencies and enabling more sophisticated higher moment bounds.

Inference for high-dimensional exchangeable arrays

2020-09-10 · Harold D. Chiang, Kengo Kato, Yuya Sasaki

We consider inference for high-dimensional separately and jointly exchangeable arrays where the dimensions may be much larger than the sample sizes. For both exchangeable arrays, we first derive high-dimensional central …

Martingale Methods for Sequential Estimation of Convex Functionals and Divergences

2021-03-16 · Tudor Manole, Aaditya Ramdas

We present a unified technique for sequential estimation of convex divergences between distributions, including integral probability metrics like the kernel maximum mean discrepancy, $\varphi$-divergences like the Kullba…

Cross-Fitting-Free Debiased Machine Learning with Multiway Dependence

2026-02-11 · Kaicheng Chen, Harold D. Chiang arxiv

This paper develops an asymptotic theory for two-step debiased machine learning (DML) estimators in generalised method of moments (GMM) models with general multiway clustered dependence, without relying on cross-fitting.…

Positive Semidefinite Matrix Supermartingales

2024-01-28 · Hongjian Wang, Aaditya Ramdas

We explore the asymptotic convergence and nonasymptotic maximal inequalities of supermartingales and backward submartingales in the space of positive semidefinite matrices. These are natural matrix analogs of scalar nonn…

Concentration Inequalities for Exchangeable Tensors and Matrix-valued Data

2026-01-28 · Chen Cheng, Rina Foygel Barber arxiv

We study concentration inequalities for structured weighted sums of random data, including (i) tensor inner products and (ii) sequential matrix sums. We are interested in tail bounds and concentration inequalities for th…
