Supervised Feature Selection via Quadratic Surface Regression with $$l_{2,1}$$ -Norm Regularization
Annals of Data Science - - Trang 1-29 - 2024
Changlin Wang, Zhixia Yang, Junyou Ye, Xue Yang, Manchen Ding
This paper proposes a supervised kernel-free quadratic surface regression method for feature selection (QSR-FS). The method is to find a quadratic function in each class and incorporates it into the least squares loss function. The $$l_{2,1}$$ -norm regularization term is introduced to obtain a sparse solution...... hiện toàn bộ
Optimization on the Turning Process Parameters of SS 304 Using Taguchi and TOPSIS
Annals of Data Science - Tập 10 - Trang 1405-1419 - 2022
Nikhil J. Rathod, Manoj K. Chopra, Prem Kumar Chaurasiya, Umesh S. Vidhate, Abhishek Dasore
Turning is a basic machining technique where parameters may be optimised to improve machining performance. The Taguchi and TOPSIS methods were used to find the parameters of optimum process in turning SS 304 using coated carbide tools. Cutting speed, feed rate, and depth of cut are all considered in the operation. This improves tool life while lowering production time and surface roughness. TOPSI ...... hiện toàn bộ
The Fréchet Topp Leone-G Family of Distributions: Properties, Characterizations and Applications
Annals of Data Science - Tập 8 - Trang 345-366 - 2019
Hesham Reyad, Mustafa Ç. Korkmaz, Ahmed Z. Afify, G. G. Hamedani, Soha Othman
A new family of continuous distributions which ensure model flexiblity, is introduced based on the Fréchet distribution and Topp Leone-G family. Two special sub-models of the new family are discussed. We provide some distributional properties of this family in the general setting such as the series expansions of density, moments, generating function, stress strength model, Rényi and Shannon entrop...... hiện toàn bộ

The Improved EWMA Chart for Heteroscedasticity Process
Annals of Data Science - Tập 5 - Trang 21-27 - 2017
Dan Zhou, Liu Liu, Xin Lai
It is doubtful of the validity of the EWMA chart that the observations from heteroscedasticity processes violate the assumption of identical distribution. In this paper, we discuss the effect of heteroscedasticity on the performance of the conventional EWMA chart. Then we analyze the principle of the improved EWMA chart for monitoring heteroscedasticity processes. Then we compare the detection per...... hiện toàn bộ
Modeling of Longitudinal Factors Under-Age Five Children Body Mass Index at Bahir Dar Districts: First Order Transition Model
Annals of Data Science - Tập 7 - Trang 581-598 - 2019
Alebachew Abebe Alemu
The body mass index (BMI) is calculated as weight in kilograms divided by square height in meters ( $$ \frac{\text{kg}}{{{\text{m}}^{2} }} $$ ). Its formula was developed by Belgium Statistician Adolphe Quetelet, and was known as the Quetelet Index (Adolphe Quetelet in BMI formula was developed. Belgium Statistician, 1796–1874. http://www.cdc.gov/healthyweight/assessing/bmi/childrens_bmi/about_childrens_bmi.htm...... hiện toàn bộ
Bivariate Weibull Distribution: Properties and Different Methods of Estimation
Annals of Data Science - Tập 7 - Trang 163-193 - 2019
Ehab Mohamed Almetwally, Hiba Zeyada Muhammed, El-Sayed A. El-Sherpieny
The bivariate Weibull distribution is an important lifetime distribution in survival analysis. In this paper, Farlie–Gumbel–Morgenstern (FGM) copula and Weibull marginal distribution are used for creating bivariate distribution which is called FGM bivariate Weibull (FGMBW) distribution. FGMBW distribution is used for describing bivariate data that have weak correlation between variables in lifetim...... hiện toàn bộ
Moments of Dual Generalized Order Statistics from Topp Leone Weighted Weibull Distribution and Characterization
Annals of Data Science - Tập 9 - Trang 1129-1148 - 2021
B. Singh, R. U. Khan, A. N. Khan
In this paper, we obtain exact explicit expressions as well as several recurrence relations satisfied by single and product moments of dual (lower) generalized order statistics from Topp-Leone weighted Weibull distribution. These relations are deduced for moments of order statistics and lower record values. Further, these recurrence relations and other properties of dual generalized order statisti...... hiện toàn bộ
Modified Beta Linear Exponential Distribution with Hydrologic Applications
Annals of Data Science - Tập 8 - Trang 131-157 - 2019
Hassan S. Bakouch, Abdus Saboor, Muhammad Nauman Khan
In this paper, we introduce a flexible modified beta linear exponential (MBLE) distribution. Our motivation, besides others are there, dues to its ability in hydrology applications. We investigate a set of its statistical properties for supporting such applications, like moments, moment generating function, conditional moments, mean deviations, entropy, mean and variance (reversed) residual life a...... hiện toàn bộ
A Joint Cognitive Latent Variable Model for Binary Decision-making Tasks and Reaction Time Outcomes
Annals of Data Science - - 2024
Mahdi Mollakazemiha, Ehsan Bahrami Samani
Traditionally, in cognitive modeling for binary decision-making tasks, stochastic differential equations, particularly a family of diffusion decision models, are applied. These models suffer from difficulties in parameter estimation and forecasting due to the non-existence of analytical solutions for the differential equations. In this paper, we introduce a joint latent variable model for binary d...... hiện toàn bộ
