This paper proposes a novel three-step aggregation method that first aligns the permutations across all local estimators via a particular spectral clustering approach, then aligns the signs within each estimated cluster via another tailored spectral approach, and finally applies the geometric median for robust aggregat...
It is shown that EM recovers the mixture atoms at the parametric rate, up to logarithmic factors, after $\mathcal{O}(\log N)$ iterations, provided atom separation is at least of order $\log K$.

Two novel analytical approaches are developed, each tailored to a different separation regime, reflecting two complementary perspectives on the use of EM: parameter estimation and clustering, which allow the number of Gaussian components, the minimum mixing weight, the component separation, and the dimension to grow wi...
Using period analysis, the most up-to-date 5-year RS for CC, EC, and OC in Taizhou, Eastern China is provided, and sustained survival improvements over the past 15 years for these cancers are found, providing epidemiological support for optimizing local gynecological cancer screening, treatment and targeted cancer cont...
