On the Weighted Mixed Almost Unbiased Ridge Estimator in Stochastic Restricted Linear Regression by Chaolin Liu, Hu Yang, Jibo Wu

“…We introduce the weighted mixed almost unbiased ridge estimator (WMAURE) based on the weighted mixed estimator (WME) (Trenkler and Toutenburg 1990) and the almost unbiased ridge estimator (AURE) (Akdeniz and Erol 2003) in linear regression model. We discuss superiorities of the new estimator under the quadratic bias (QB) and the mean square error matrix (MSEM) criteria. …”

Norm‐based zeroing neural dynamics for time‐variant non‐linear equations by Linyan Dai, Hanyi Xu, Yinyan Zhang, Bolin Liao

“…Abstract Zeroing neural dynamic (ZND) model is widely deployed for time‐variant non‐linear equations (TVNE). Various element‐wise non‐linear activation functions and integration operations are investigated to enhance the convergence performance and robustness in most proposed ZND models for solving TVNE, leading to a huge cost of hardware implementation and model complexity. …”

Designing of Adaptive Model-Free Controller Based on Output Error and Feedback Linearization by S. Pezeshki, M. A. Badamchizadeh, S. Ghaemi, M. A. Poor

“…This paper introduces a new approach to design Model-Free Adaptive Controller (MFAC) using adaptive fuzzy procedure as a feedback linearization based on output error. The basic idea is to transfer the control signal to an appropriate surface and then, depending on the output error of system, the control signal changes around this surface. …”
