Symbolic dynamics and representations

چکیده
The object of study of symbolic dynamics are discrete dynamical systems made of infinite sequences of symbols, with the shift acting on them. They come as codings of trajectories of points in a dynamical system according to a given partition. They are used as discretization tools for analyzing such trajectories, but they also occur in a natural way in arithmetics for instance. We first will recall basic definitions concerning symbolic dynamics and illustrate them with transformations like beta-numeration and continued fractions. We then focus on orbits that are relevant in computer science, namely finite and periodic ones, together by alluding to numerical issues for the computation of orbits.

A New Approach to Detect Congestive Heart Failure Using Symbolic Dynamics Analysis of Electrocardiogram Signal
The aim of this study is to show that the measures derived from Electrocardiogram (ECG) signals many a time perform better than the same measures obtained from heart rate (HR) signals. A comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ECG signals and HR signals, and thereby discriminate between normal and cong...

متن کاملSymbolic Representations of Iterated Maps November 14 , 2000
This paper presents a general and systematic discussion of various symbolic representations of iterated maps through subshifts. We give a unified model for all continuous maps on a metric space, by representing a map through a general subshift over usually an uncountable alphabet. It is shown that at most the second order representation is enough for a continuous map. In particular, it is shown...

متن کاملSynthesis of Recursive Symbolic Models for Articulated Robotic Systems
We discuss the importance of a recursive, symbolic model of articulated robot dynamics for various aspects of multibody system design. Drawing from and extending the results of recent, seemingly disparate, research into the structure of articulated rigid{body systems, a uniied model is presented. New and intuitive derivations are also presented. The model highlights the unique algebraic structu...
متن کاملTowards Bridging the Gap Between Pattern Recognition and Symbolic Representation Within Neural Networks
Underlying symbolic representations are opaque within neural networks that perform pattern recognition. Neural network weights are sub-symbolic, they commonly do not have a direct symbolic correlates. This work shows that by implementing network dynamics differently, during the testing phase instead of the training phase, pattern recognition can be performed using symbolically relevant weights....
