On the convergence of Steffensen-type methods using recurrent functions nonexpansive mappings

Journal of Numerical Analysis and Approximation Theory, 2009
We introduce the new idea of recurrent functions to provide a new semilocal convergence analysis for Steffensen-type methods (STM) in a Banach space setting.

Semilocal convergence conditions for the secant method, using recurrent functions

Journal of Numerical Analysis and Approximation Theory, 2011
Using our new concept of recurrent functions, we present new sufficient convergence conditions for the secant method to a locally unique solution of a nonlinear equation in a Banach space.

General Recurrent Neural Network for Solving Generalized Linear Matrix Equation

Complexity, 2017
This brief proposes a general framework of the nonlinear recurrent neural network for solving online the generalized linear matrix equation (GLME) with global convergence property. If the linear activation function is utilized, the neural state matrix of

On Newton's method using recurrent functions under hypotheses up to the second Fréchet derivative

Journal of Numerical Analysis and Approximation Theory, 2012
We provide semilocal result for the convergence of Newton method to a locally unique solution of an equation in a Banach space setting using hypotheses up to the second Fréchet-derivatives and our new idea of recurrent functions.

Recurrent Value Functions

, 2019
Despite recent successes in Reinforcement Learning, value-based methods often suffer from high variance hindering performance. In this paper, we illustrate this in a continuous control setting where state of the art methods perform poorly whenever sensor noise is introduced.

Recurrent Highway Networks

, 2017
Many sequential processing tasks require complex nonlinear transition functions from one step to the next. However, recurrent neural networks with 'deep' transition functions remain difficult to train, even when using Long Short-Term Memory (LSTM ...

Extinction and recurrence of multi-group SEIR epidemic [PDF]

, 2013
In this paper, we consider a class of multi-group SEIR epidemic models with stochastic perturbations. By the method of stochastic Lyapunov functions, we study their asymptotic behavior in terms of the intensity of the stochastic perturbations and the ...

Pathogenetic bases and efficacy of slow calcium channel blockers in the therapy of recurrent peptic ulcer disease associated with hypertension [PDF]

Терапевтический архив, 2017
Aim. To clarify blood calcium concentrations (BCCs) as an indicator of the functional state of the calcium-regulating system in the concomitant course of recurrent peptic ulcer disease (PUD) and hypertension, by comparing with the severity of a ulcerous ...
