Constructing efficient strata boundaries in stratified sampling using survey cost [PDF]
Heliyon, 2023 For maximum precision in population parameter estimation under the Stratified sampling design, the optimum strata boundaries (OSB) could be constructed based on a continuous study variable rather than a set of categorical variables.

Federated learning based on stratified sampling and regularization
Complex & Intelligent Systems, 2022 Federated learning (FL) is a new distributed learning framework that is different from traditional distributed machine learning: (1) differences in communication, computing, and storage performance among devices (device heterogeneity), (2) differences in

Estimation of Sensitive Attributes Using a Stratified Kuk Randomization Device
Revista Colombiana de Estadística, 2017 This paper suggests a stratified Kuk model to estimate the proportion of sensitive attributes of a population composed by a number of strata; this is undertaken by applying stratified sampling to the adjusted Kuk model.

Calibration-Based Mean Estimators under Stratified Median Ranked Set Sampling
Mathematics, 2023 Using auxiliary information, the calibration approach modifies the original design weights to enhance the mean estimates. This paper initially proposes two families of estimators based on an adaptation of the estimators presented by recent researchers ...

Assessing Antithetic Sampling for Approximating Shapley, Banzhaf, and Owen Values
AppliedMath, 2023 Computing Shapley values for large cooperative games is an NP-hard problem. For practical applications, stochastic approximation via permutation sampling is widely used. In the context of machine learning applications of the Shapley value, the concept of
