The Berry-Esseen Constant Conjecture is Eventually True
Hengzhi He, Guang Cheng
We prove that the Esseen's constant is valid in the iid Berry--Esseen inequality as long as the sample sizes . The threshold is universal over all real summ…
Fractional Triangle Decompositions at Partite Minimum Degree
Hengzhi He, Guang Cheng
We prove that every triangle-divisible balanced tripartite graph whose vertex classes have size and whose partite minimum degree is at least admits a fractional triangle…
Tensor-normal maximum likelihood estimation at the operator-norm sample threshold
Hengzhi He, Guang Cheng
Let be independent Gaussian tensors in with a common covariance matrix given by the Kronecker product of …
Asymptotically Lossless Exact and Pivotal E-Values
Hengzhi He, Guang Cheng
Consider testing a finite composite null $\cP={P_1,\ldots,P_L}$ against a simple alternative using i.i.d. observations. Let denote the supremum of the expected log…
Sharp proper estimation of fixed-component Gaussian location mixtures in polynomial time
Hengzhi He, Guang Cheng
We consider a mixture of at most unit-covariance Gaussians in whose means belong to a fixed-radius ball, with no separation or minimum-weight condition. Doss, Wu…
Let the Target Select for Itself: Data Selection via Target-Aligned Paths
Huitao Yang, Hengzhi He, Guang Cheng +1
Targeted data selection seeks training examples from a candidate pool that improve downstream task performance. While trajectory-based selectors effectively guide this process, exi…
Authenticated Contradictions from Desynchronized Provenance and Watermarking
Alexander Nemecek, Hengzhi He, Guang Cheng +1
Cryptographic provenance standards such as C2PA and invisible watermarking are positioned as complementary defenses for content authentication, yet the two verification layers are…
