چکیده
In a previous work Pollack showed that a particular type of heterogeneous processor network is Turing universal. Siegelmann and Sontag (1991) showed the universality of homogeneous networks of first-order neurons having piecewise-linear activation functions. Their result was generalized by Kilian and Siegelmann (1996) to include various sigmoidal activation functions. Here we focus on a type of high-order neurons called switch-affine neurons, with piecewise-linear activation functions, and prove that nine such neurons suffice for simulating universal Turing machines. q 1999 Elsevier Science Ltd.

Coherence resonance and discharge time reliability in neurons and neuronal models
Neurons are subject to internal and external noise that have been known to modify the way they process incoming signals. Recent studies have suggested that such alterations have functional roles and can also be used in biomedical applications. The present work goes over experimental and theoretical descriptions of the response of neurons to white noise stimulation. It examines various forms of ...

This paper presents a theoretical analysis on the asymptotic memory capacity of the generalized Hopfield network. The perceptron learning scheme is proposed to store sample patterns as the stable states in a generalized Hopfield network. We have obtained that n 2 1 and 2n are a lower and an upper bound of the asymptotic memory capacity of the network of n neurons, respectively, which shows th...
متن کاملApplication of the kernel method to the inverse geosounding problem
Determining the layered structure of the earth demands the solution of a variety of inverse problems; in the case of electromagnetic soundings at low induction numbers, the problem is linear, for the measurements may be represented as a linear functional of the electrical conductivity distribution. In this paper, an application of the support vector (SV) regression technique to the inversion of...

The aim of the paper is to investigate the application of control schemes based on “internal models” to the stabilization of the standing posture. The computational complexities of the control problems are analyzed, showing that muscle stiffness alone is insufficient to carry out the task. The paper also re-visits the concept of the cerebellum as a Smith’s predictor. q 1999 Elsevier Science Ltd...

This paper presents a learning approach, i.e. negative correlation learning, for neural network ensembles. Unlike previous learning approaches for neural network ensembles, negative correlation learning attempts to train individual networks in an ensemble and combines them in the same learning process. In negative correlation learning, all the individual networks in the ensemble are trained sim...
