An ECG Signals Compression Method and Its Validation Using NNs
C.M. Fira,Liviu Goras +1 more
TL;DR: This paper presents a new algorithm for electrocardiogram (ECG) signal compression based on local extreme extraction, adaptive hysteretic filtering and Lempel-Ziv-Welch (LZW) coding, which takes into account both the reconstruction errors and the compression ratio.
Journal ArticleDOI
Turing patterns in CNNs. II. Equations and behaviors
Liviu Goras,Leon O. Chua +1 more
TL;DR: The general state equations describing two-grid coupled CNNs based on the reduced Chua's circuit are derived, and the analysis of Turing pattern formation is approached from a specific point of view: spatial-eigenfunction based equation decoupling.
Journal ArticleDOI
Turing patterns in CNNs. I. Once over lightly
TL;DR: This three part tutorial derives the first two conditions for Turing pattern formation, discusses the boundary conditions, and illustrates via an example on how the number of the equilibrium points of a CNN increases rapidly even though each isolated cell has only one equilibrium point.
Journal ArticleDOI
On ECG Compressed Sensing using Specific Overcomplete Dictionaries
TL;DR: The paper presents a number of results regarding the construction of specific overcomplete dictionaries for ECG compressed sensing (CS), and these dictionaries were built using normal and ordinary dictionaries.
Journal ArticleDOI
Turing patterns in CNNs. III. Computer simulation results
TL;DR: In this paper, various patterns obtained through computer simulations are presented and it is shown through simple examples that the four inequalities known as the Turing instability conditions are only necessary but not sufficient conditions for Turing patterns to exist.
