AbstractIn this work, we present patterns and pseudo-randomness in an approach that relates both concepts, which traditionally are seen as opposites. This approach uses the mathematical basis of complex systems for two purposes: to exploit the spectrum of pseudo-randomness of chaotic systems in a quest to achieve true randomness and, the development of pattern recognition methods based on artificial life in complex networks that finally intertwined the search for patterns in pseudo-random sequences. In the first part, we developed a method to explore the depth properties of chaotic systems, specifically in the logistic map and tent map, as sources of pseudo-randomness. We observe that the patterns disappear and the pseudo-randomness is increased by removing k-digits to the right of the decimal separator of the chaotic orbits. Thus, a rapid transition from "weak to strong" randomness was evidenced as k tends to infinity, which allows a parametrically pseudo-randomness. In the second part, it was proposed the combination of cellular automata in the network topology (also called network-automata), to characterize networks in a pattern recognition context. Four problems were explored: identifying online social networks; identify organisms from different domains of life through their metabolic networks; the problem of authorship identification; and classifying stomatal distribution patterns varying according to different environmental conditions. Finally, this same approach was used to analyze the sequences of pseudo-random numbers generated by the gold standard k-logistic map PRNG in a context of pattern recognition. The proposed approach allowed to explore patterns and pseudo-randomness extracted from a myriad of systems with successful results in terms of accuracy and good pseudo-randomness. This work has brought significant advances in real-world pattern recognition tasks across a wide range of fields such as cryptography, cryptoanalysis, biology, and data science.
