Many scientific disciplines such as physics, bio-systems, new technologies and economics create models according to the behaviour of nonlinear dynamical systems and work on these subjects. Therefore, this article will focus on how these systems are studied by giving well-known a few examples of nonlinear dynamical systems. Also, the various definitions of entropy, which has an important place in the behaviour of physical systems or information theory, will be discussed. In addition, general concepts of the complexity science that are directly related to nonlinear systems will be briefly emphasized.

In such a world where countries need to take action to shape their future in accordance with this ‘new normal’, the policies followed by countries in high technological sectors will be determinative on their positions within global value chains in the future. Based on this, international trade of industrial robots among the Belt and Road Initiative members is analyzed via complex network tools in the present study. The empirical results indicated that the international trade network of industrial robots has complex system properties such as power-law distribution, disassortativity, core-periphery structure etc. The results also revealed that developing members of the Initiative may exploit export hubs of the network, namely South Korea, Singapore, Austria and Italy in order to digitalize their economies in the short-term.

A complex system results from a huge amount of interactions of many agents following simple rules. It is not the agents that are essential, but the relationships between them. Deep learning models created a much greater paradigm change in solving engineering problems than the one created by complex systems in science. Deep learning models are composed of a layered structure. The first layers automatically learn the simplest features, while the next layers have the ability to extract highlevel features in a hierarchical manner form simple to more complex. Special deep learning algorithms can even capture temporal and spatial relationships. The purpose of this article is to emphasize the fact that data science, machine learning and complex systems will provide us a complementary perspective to study our universe.
