A new class activation functions with application in the theory of impulse technics
Journal of Mathematical Sciences and Modelling, 2018 In this note we define the new activation functions, based on the well-known hyperbolic tangent and half--hyperbolic tangent activation functions. We consider the Hausdorff distance between the ''double step'' function $\sigma^{\ast}(t)$ (resp. function $

International Review of Electrical Engineering (IREE), 2016 If the mathematical description of the magnetic hysteresis loop branches should be simple, easy to use and should credibly describe the waveform magnetic hysteresis loop with a minimum number of parameters, then it inevitably leads to the description of magnetic hysteresis loop branches with a hyperbolic tangent function.

A Novel Method for Scalable VLSI Implementation of Hyperbolic Tangent Function [PDF]
IEEE Design & Test, 2022 Hyperbolic tangent and Sigmoid functions are used as non-linear activation units in the artificial and deep neural networks. Since, these networks are computationally expensive, customized accelerators are designed for achieving the required performance at lower cost and power.

A New Wavelet Thresholding Function Based on Hyperbolic Tangent Function
Mathematical Problems in Engineering, 2015 Thresholding function is an important part of the wavelet threshold denoising method, which can influence the signal denoising effect significantly. However, some defects are present in the existing methods, such as function discontinuity, fixed bias, and parameters determined by trial and error.

A Variable Step-size CLMS Algorithm and Its Analysis [PDF]
Radioengineering, 2020 In this paper, a hyperbolic tangent variable step-size convex combination of the least mean square (HTVSCLMS) algorithm is proposed and analyzed. This work avoids the compromise between the convergence speed and the steady-state error for two filters in ...

Hybrid Models for Solving the Colebrook–White Equation Using Artificial Neural Networks
Fluids, 2022 This study proposes hybrid models to solve the Colebrook–White equation by combining explicit equations available in the literature to solve the Colebrook–White equation with an error function. The hybrid model is in the form of fH=fo−eA.

A New AILC for a Class of Nonlinearly Parameterized Systems with Unknown Delays and Input Dead-Zone
Journal of Applied Mathematics, 2014 This paper presents an adaptive iterative learning control (AILC) scheme for a class of nonlinear systems with unknown time-varying delays and unknown input dead-zone. A novel nonlinear form of deadzone nonlinearity is presented.
