Available in PDF, EPUB and Kindle. Book excerpt: "Many physical, biological, social and technological systems have astonishing complex organization. They are all composed of individual components that are interacting with each other in a certain fashion. Such systems can be represented by networks that provide a convenient framework to analyze their topological properties. Understanding structural organization of networks is imperative to study dynamical processes that are taking place over them and to model many real-world complex systems. Some examples include the spread of news or information in a social network or the robustness of Internet to cascading failures of routers. It was previously reported that the underlying network architecture is able to control and shape these associated nonlinear dynamical processes. In this thesis, we aim at uncovering the exact connection between certain dynamical processes and complex topology of networks. More precisely, we study pattern formation as well as percolation phenomena. We first articulate theoretical perspectives by studying reaction diffusion models and percolation processes on synthetic networks. This gives us the freedom to systematically tune the underlying network architecture by random graph models and monitor the effects on the dynamics. Our results shed new light on the complex interplay between structure and dynamics that motivate us to investigate realistic scenarios. For each case, we extend our work to real world networks by performing analyses that capture empirical aspects of the systems considered. Namely, we propose an application to model the evolution of competing languages in a geographical region that spread over a contact network representing population flows. We show the robustness and generalizability of our framework on two different data-sets and discuss more applications in other socioeconomic systems, such as opinion formation. Additionally, we develop a machine learning approach to study percolation transition happening on time evolving networks. We find that identifying correct node subsets through a microscopic decomposition technique yields accurate results for the classification of sub-critical and super-critical percolation phases as well as for prediction of critical transition point. We test our method on two different real world settings for both purposes and propose further applications. Lastly, we finish the thesis with a pure empirical study to predict urban economic welfare through the structural analysis of global mobility network. We first determine the most effective network-based predictor of economic prosperity by its correlation to various socioeconomic indicators. We then develop a generative model that captures the costs and benefits of allocating out-flows of each urban area towards its neighbors. Our results hint at the importance of leveraging inter-urban connections for urban development and welfare"--Pages ix-x

Book Synopsis Dynamical Processes on Complex Networks by : Alain Barrat
Download or read book Dynamical Processes on Complex Networks written by Alain Barrat and published by Cambridge University Press. This book was released on 2012-10-11 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability of large data sets have allowed researchers to uncover complex properties such as large scale fluctuations and heterogeneities in many networks which have lead to the breakdown of standard theoretical frameworks and models. Until recently these systems were considered as haphazard sets of points and connections. Recent advances have generated a vigorous research effort in understanding the effect of complex connectivity patterns on dynamical phenomena. For example, a vast number of everyday systems, from the brain to ecosystems, power grids and the Internet, can be represented as large complex networks. This new and recent account presents a comprehensive explanation of these effects.

Book Synopsis Machine Learning in Complex Networks by : Thiago Christiano Silva
Download or read book Machine Learning in Complex Networks written by Thiago Christiano Silva and published by Springer. This book was released on 2016-01-28 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the features and advantages offered by complex networks in the machine learning domain. In the first part, an overview on complex networks and network-based machine learning is presented, offering necessary background material. In the second part, we describe in details some specific techniques based on complex networks for supervised, non-supervised, and semi-supervised learning. Particularly, a stochastic particle competition technique for both non-supervised and semi-supervised learning using a stochastic nonlinear dynamical system is described in details. Moreover, an analytical analysis is supplied, which enables one to predict the behavior of the proposed technique. In addition, data reliability issues are explored in semi-supervised learning. Such matter has practical importance and is not often found in the literature. With the goal of validating these techniques for solving real problems, simulations on broadly accepted databases are conducted. Still in this book, we present a hybrid supervised classification technique that combines both low and high orders of learning. The low level term can be implemented by any classification technique, while the high level term is realized by the extraction of features of the underlying network constructed from the input data. Thus, the former classifies the test instances by their physical features, while the latter measures the compliance of the test instances with the pattern formation of the data. We show that the high level technique can realize classification according to the semantic meaning of the data. This book intends to combine two widely studied research areas, machine learning and complex networks, which in turn will generate broad interests to scientific community, mainly to computer science and engineering areas.

Book Synopsis Modularity and Dynamics on Complex Networks by : Renaud Lambiotte
Download or read book Modularity and Dynamics on Complex Networks written by Renaud Lambiotte and published by Cambridge University Press. This book was released on 2022-02-03 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex networks are typically not homogeneous, as they tend to display an array of structures at different scales. A feature that has attracted a lot of research is their modular organisation, i.e., networks may often be considered as being composed of certain building blocks, or modules. In this Element, the authors discuss a number of ways in which this idea of modularity can be conceptualised, focusing specifically on the interplay between modular network structure and dynamics taking place on a network. They discuss, in particular, how modular structure and symmetries may impact on network dynamics and, vice versa, how observations of such dynamics may be used to infer the modular structure. They also revisit several other notions of modularity that have been proposed for complex networks and show how these can be related to and interpreted from the point of view of dynamical processes on networks.

Book excerpt: This elementary book provides some state-of-the-art research results on broad disciplinary sciences on complex networks. It presents an in-depth study with detailed description of dynamics, controls and applications of complex networks. The contents of this book can be summarized as follows. First, the dynamics of complex networks, for example, the cluster dynamic analysis by using kernel spectral methods, community detection algorithms in bipartite networks, epidemiological modeling with demographics and epidemic spreading on multi-layer networks, are studied. Second, the controls of complex networks are investigated including topics like distributed finite-time cooperative control of multi-agent systems by applying homogenous-degree and Lyapunov methods, composite finite-time containment control for disturbed second-order multi-agent systems, fractional-order observer design of multi-agent systems, chaos control and anticontrol of complex systems via Parrondos game and many more. Third, the applications of complex networks provide some applicable carriers, which show the importance of theories developed in complex networks. In particular, a general model for studying time evolution of transition networks, deflection routing in complex networks, recommender systems for social networks analysis and mining, strategy selection in networked evolutionary games, integration and methods in computational biology, are discussed in detail.
