Europhysics Letters Robust Chaos Generation by a Perceptron
{ The properties of time series generated by a perceptron with monotonic and non-monotonic transfer function, where the next input vector is determined from past output values, are examined. Analysis of the parameter space reveals the following main nding: a perceptron with a monotonic function can produce fragile chaos only whereas a non-monotonic function can generate robust chaos as well. Fo...
متن کاملRobust Chaos
It has been proposed to make practical use of chaos in communication [1], in enhancing mixing in chemical processes [2] and in spreading the spectrum of switch-mode power suppies to avoid electromagnetic interference [3, 4]. In such applications it will be necessary to obtain reliable operation in the chaotic mode. It is known that for most smooth chaotic systems (take the logistic map [5] for ...
متن کاملA Chaos-Based Robust Software Watermarking
In this paper we propose a robust software watermarking based on chaos against several limitations of existing software watermarking. The algorithm combines the anti-reverse engineering technique, chaotic system and the idea of Easter Egg software watermarks. The global protection for the program is provided by dispersing watermark over the whole code of the program with chaotic dispersion codi...
متن کاملInformation Processing by a Perceptron
The information coming into a module, which is part of a global system, will in general require pre-processing that consists in building a representation-expressing it in a new code-convenient to the task to be performed by this particular module. This information, coming either from the environment or from another module in the system, will undergo this operation in what we can call an encoder...
متن کاملRobust chaos in neural networks
We consider the problem of creating a robust chaotic neural network. Robustness means that chaos cannot be destroyed by arbitrary small change of parameters [Phys. Rev. Lett. 80 (1998) 3049]. We present such networks of neurons with the activation function f (x) = | tanh s(x − c)|. We show that in a certain range of s and c the dynamical system xk+1 = f (xk) cannot have stable periodic solution...
