New modified exponentially weighted moving average-moving average control chart for process monitoring

open access: yesConnection Science, 2022
The mixed control chart is proposed to improve detection performance with fewer process shifts. In this study, we proposed the modified exponentially weighted moving average - moving average control chart (MMEM), a new mixed control chart for observing ...

Evaluations of a Weighted Average of Gauss Sums

open access: yesJournal of Mathematics, 2021
In this paper, we perform a further investigation for a weighted average of Gauss sums. By making use of some properties of the cotangent function and the Bernoulli polynomials, we explicitly evaluate the weighted average of Gauss sums in terms of the ...

Reducing Susceptibility Distortion Related Image Blurring in Diffusion MRI EPI Data

open access: yesFrontiers in Neuroscience, 2021
Diffusion magnetic resonance imaging (MRI) is an increasingly popular technique in basic and clinical neuroscience. One promising application is to combine diffusion MRI with myelin maps from complementary MRI techniques such as multi-parameter mapping ...

Exponentially weighted moving average-Moving average charts for monitoring the process mean.

open access: yesPLoS ONE, 2020
This research aimed to propose a newly-mixed control chart called the Exponentially Weighted Moving Average-Moving Average Chart (EWMA-MA) to detect the mean change in a process underlying symmetric and asymmetric distributions.

Stochastic Weight Averaging Revisited

open access: yesApplied Sciences, 2023
Averaging neural network weights sampled by a backbone stochastic gradient descent (SGD) is a simple-yet-effective approach to assist the backbone SGD in finding better optima, in terms of generalization. From a statistical perspective, weight-averaging contributes to variance reduction.

Attribute Value Weighted Average of One-Dependence Estimators

open access: yesEntropy, 2017
Of numerous proposals to improve the accuracy of naive Bayes by weakening its attribute independence assumption, semi-naive Bayesian classifiers which utilize one-dependence estimators (ODEs) have been shown to be able to approximate the ground-truth ...

Slice weighted average regression

open access: yesAdvances in Data Analysis and Classification, 2023
Abstract It has previously been shown that ordinary least squares can be used to estimate the coefficients of the single-index model under only mild conditions. However, the estimator is non-robust leading to poor estimates for some models.
