ON SIMPLE BOUNDS FOR INVERSE HYPERBOLIC SINE AND INVERSE HYPERBOLIC TANGENT FUNCTIONS

Jnanabha, 2021
We obtain simple algebraic bounds of inverse hyperbolic sine and inverse hyperbolic tangent functions i.e., sinh⁻¹ x and tanh⁻¹ x. The inequalities are obtained on the entire domains of these functions. From our results, we obtain tighter bounds for the same functions.

Support vector classifier with hyperbolic tangent penalty function

2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002
The support vector classifier is a new tool to solve classification problems, giving the classification boundary as a linear combination of the training samples. In non-separable problems with highly overlapped classes, the achieved classifiers are oversized.

Efficient hardware implementation of the hyperbolic tangent sigmoid function

2009 IEEE International Symposium on Circuits and Systems, 2009
Efficient implementation of the activation function is important in the hardware design of artificial neural networks. Sigmoid, and hyperbolic tangent sigmoid functions are the most widely used activation functions for this purpose. In this paper, we present a simple and efficient architecture for digital hardware implementation of the hyperbolic ...

A HYPERBOLIC TANGENT YIELD FUNCTION OF FLORIDA CITRUS

2007
This study models Florida citrus production as a function of the age profile of a given tree stock. The age relationship is estimated using a modified hyperbolic tangent function and the parameters is solved by Spatial Process Models and Maximum Likelihood approach.

Design of Current Mode Sigmoid Function and Hyperbolic Tangent Function

2019
In this paper, two design procedures for sigmoid function using exponential function have been proposed implementing division operation and feedback methodology. Hyperbolic tangent function has also been synthesized using the later. All the proposed circuits along with their building blocks have been implemented using current mode device Operational ...

Outlier Detection using Weighted Holoentropy with Hyperbolic Tangent Function

International Journal of Data Analysis Techniques and Strategies, 2018
Numerous research works has been carried out in the literature to detect the outlier's a.k.a anomalies. Outlier detection is considered as a pre-processing step for locating those objects in a dataset that do not conform to well-defined notions of expected behaviour.

A hyperbolic tangent identity and the geometry of Padé sign function iterations

Numerical Algorithms, 1994
This paper consists of two parts. First, the rational iterations obtained from certain Padé approximations associated with computing the matrix sign function are shown to be equivalent to iterations involving the hyperbolic tangent and its inverse. Using this equivalent formulation many results about these Padé iterations, such as global convergence ...

Approximation of hyperbolic tangent activation function using hybrid methods

2013 8th International Workshop on Reconfigurable and Communication-Centric Systems-on-Chip (ReCoSoC), 2013
Artificial Neural Networks are widely used in various applications in engineering, as such solutions of nonlinear problems. The implementation of this technique in reconfigurable devices is a great challenge to researchers by several factors, such as floating point precision, nonlinear activation function, performance and area used in FPGA.

Hyperbolic-tangent-function-based cyclic correlation: Definition and theory

Signal Processing, 2019
Abstract Non-stationary, non-Gaussian signal processing is a challenging topic in signal processing research. Over the past decade, due to effectively addressing co-channel interference, cyclostationarity-based methodologies have found a wide range of applications, such as wireless communication, cognitive radio, and mechanical vibration monitoring ...

Computing hyperbolic tangent and sigmoid functions using stochastic logic

2016 50th Asilomar Conference on Signals, Systems and Computers, 2016
This paper addresses implementations of tangent hyperbolic and sigmoid functions using stochastic logic. Stochastic computing requires simple logic gates and is inherently fault-tolerant. Thus, these structures are well suited for nanoscale CMOS technologies.
