Jennifer A. Dunne
Sante Fe Institute
Network science has provided powerful tools for analyzing and modeling many aspects of the organization, function, and stability of ecosystems. In particular, network-based approaches to the study of complex species interactions have led to new understanding of general patterns and processes of ecological structure and dynamics, and of the community-level consequences of species loss and other perturbations. However, most such research has focused on extant systems, on systems that are putatively human-free, and on trophic networks (e.g., food webs). This talk will discuss recent reconstructions and analyses of deep-time ecological network data, from hundreds to hundreds of millions of years ago, that move beyond these constraints. Research on ancient systems is providing new ways to address questions about the sustainability of modern socio-ecological systems.
Jennifer’s research interests are in analysis, modeling and theory related to the organization, dynamics and function of ecosystems, with a focus on ecological networks. Using cross-system analysis and computational modeling, Jennifer seeks to identify fundamental patterns and principles of ecological network structure and dynamics at multiple spatial and temporal scales. Such research provides a useful framework for understanding ecological robustness and persistence, including how humans fit into and impact ancient, historic, and current ecosystems.
Her research has been covered in Scientific American, Wired, SmartPlanet, ScienceNow, and Nature News. She has served as an editor at the Journal of Complex Networks, Ecology Letters, and Oikos, is an Oxford Series in Ecology and Evolution editor, and is an advisor to the science and culture magazine Nautilus.
Social platforms are an ideal place for spreading rumors and fake news. As more people seek information and read news online, automatically debunking such false claims has become an urgent problem. Recent years have seen great advances in data-driven rumor research. This talk will review some of its major developments, including how a comprehensive set of user, structural, linguistic, and temporal features help us better understand their propagation processes. In detecting rumors and fake news in the wild, time becomes a critical factor. This talk will present how the significance of features changes by time and which features are prominent for early detection. I will also highlight the latest detection studies with deep learning techniques.

Monash Institute of Cognitive and Clinical Neurosciences
Functional segregation and integration are two fundamental pillars of brain organization. Functional segregation is supported by a modular topology and functional integration is supported by high inter-connectivity of hub regions (rich-club organization). In this talk I will present evidence from macroscale brain imaging in humans that this interplay between segregated and integrated activity is dynamic and context-dependent. Combining mesoscale tract-tracing, transcriptomics and functional magnetic resonance imaging in the mouse, we have found that the activity of hub regions is dominated by low-frequency dynamics and that hub connectivity has a distinctive genomic signature that is characterized by elevated coexpression of genes regulating energy metabolism. We have also found that this genomic signature of hub connectivity is conserved across species and resolution scales, being apparent in the microscale nervous system of the nematode worm C elegans. Our findings are consistent with a hierarchy of dynamical timescales and metabolic demand in the brain, such that hub regions integrate information over wide temporal windows and at high energetic cost.
Alex Fornito completed a PhD in the Departments of Psychology and Psychiatry at the University of Melbourne, Australia, followed by Post-Doctoral training at the University of Cambridge, UK. He is currently an Associate Professor, Australian Research Council Future Fellow, and co-Director of the Brain and Mental Health Laboratory in the Monash Institute of Cognitive and Clinical Neurosciences. Alex’s research uses cognitive neuroscience, network science and graph theory to understand brain network organization in health and disease. In particular, he focuses on the development and application of new methods to understand how brain networks dynamically adapt to changing task demands, how they are disrupted by disease, and how they are shaped by genetic influences. Together with co-authors Andrew Zalesky and Ed Bullmore, he recently published the first text book on network analysis for neuroscience, entitled Fundamentals of Brain Network Analysis.
University of California Santa Cruz
Network data (e.g., communication data, financial transaction networks, data describing biological systems, collaboration networks, the Web, etc.) is ubiquitous. While this observational data is useful, it is usually noisy, often only partially observed, and only hints at the actual underlying social, scientific or technological structures that give rise to the interactions. For example, an email communication network provides useful insight, but is not the same as the “real” social network among individuals. In this talk, I introduce the problem of graph identification, i.e., the discovery of the true graph structure underlying an observed network. This involves inferring the nodes, edges, and node labels of a hidden graph based on evidence provided by the observed graph. I show how this can be cast as a collective probabilistic inference task and describe a scalable approach to solving this problem.

Why should network scientists be interested in art and culture? Why should historians of art and culture be interested in network science? Why does NetSci2017 officially call for contributions in "arts and design"? And why does the main conference feature a session on "culture"? This talk will provide reasoning regarding these questions, both documenting the rise of a vibrant community, and outlining challenges that are central to both network science and the study of art and culture. A NetSci satellite theme with more than 60 contributions from more than 37 disciplines since 2009, network analysis now permeates data-driven research in art and culture, while culture analytics increasingly establishes itself as a science.

M. Ángeles Serrano
University of Barcelona
Complex networks display a hidden metric structure, which determines the likelihood and intensity of interactions. This quality has been exploited to map real networks, producing geometric representations that can be used as a guide for their efficient navigation and that shed light on pivotal forces --like preferentiality, localization, and hierarchization-- that rule their structure and evolution. Now, the powerful methods that unveil network geometry enable to disentangle the multiple scales coexisting in real networks, strongly intertwined due to the small world property. We have defined a geometric renormalization group for complex networks embedded in an underlying space that allows for a rigorous investigation of networks as viewed at different length scales. We find that real scale-free networks show geometric scaling under this renormalization group transformation. This feature enables us to unfold them in a self-similar multilayer shell which reveals the coexisting scales and their interplay. The multiscale unfolding brings about immediate practical applications. Among many possibilities, it yields a natural way of building high-fidelity smaller-scale replicas of large real networks, and sustains the design of a new multiscale navigation protocol in hyperbolic space which boosts the success of single-layer versions.

In most areas of human performance the path to major accomplishments requires a steep learning curve, long practice and many trials. Athletes go through years of training and compete repeatedly before setting new records; musicians practice from an early age and perform in secondary venues before earning the spotlight. Yet, little is known about the quantitative patterns that lead to success in creative fields. In this talk we provide a quantitative framework to describe the evolution of success in scientific and artistic careers, and ask: Are there quantifiable signs of an impending career hit? Is the success of a particular work predictable? Are there network measures that improve our understanding of success? We show that in scientific careers impact, as measured by influential publications, is distributed randomly within a scientist’s sequence of publications, and that this random impact rule allows us to formulate a stochastic model to uncouple the effects of productivity, individual ability and luck, unveiling the existence of universal patterns governing the emergence of scientific success. Further we focus on trajectories of visual artists, and show that the prestige of institutions, quantified through network measures, fully determines an artist’s future success. Starting in prestigious venues increases the chance of exhibiting in more venues, appealing to a more international audience, and of being successful in the auction market.

There has been a lot of researches on coordination behaviors on complex networks, however, competitive behaviors are also very common on real world complex networks. This talk will introduce our recent works on analysis and control of competitive behaviors on complex networks. In particular, the talk will focus on the influence of network structure and positions of competitors on the result of competition. We first consider a dynamical network model in which two competitors have fixed and different states, and each normal agent adjusts its state according to a distributed consensus protocol. The state of each normal agent converges to a steady value which is a convex combination of the competitors' states. We compute an Influence Matrix (IM) in which each element characterizing the influence of an agent on another one in the network. We use the IM to predict the bias of each normal agent and thus predict which competitor will win. Furthermore, we compare the IM criterion with several centrality-based criteria. Then, we investigate the influence maximization problem in which a competitor tries to add a number of links so as to maximize the relative influence of the competitor over the other one. Finally, we generalize the model to the case with more than two competitors.
