Host City: Milan, Italy

Milan, the capital of Lombardy, is Italy's economic and financial heart. Fashion, design, finance and media are the advanced sectors that drive its economy. Milan has eleven university centers with 44 faculties and 174,000 new students each year. This history in education and advanced research goes hand in hand with invention and innovation from the Romans to Leonardo da Vinci and Marconi and continues in recent years. The great Italian masters of the past have left their sign on the history of art, followed in the 20th century by internationally influential Futurists and Arte Povera group. Milan offers a total of 150 art galleries, 28 museums and 38 theatres.  Opera lovers will be able to enjoy performances at La Scala. For more information about the city and what’s going on in Milan refer to the tourism official website.

Host Institution: The University of Milan

A leading institute in Italy and Europe for scientific productivity, the University of Milan is the largest university in the region, with approximately. The University of Milan also possesses a remarkable artistic and cultural heritage that includes important historic buildings, inherited and acquired collections, archives, botanical gardens and the old Brera Observatory commissioned by Maria Teresa of Austria. The University’s departments are housed in important historic edifices in the centre of Milan and in modern buildings in the area known as Città Studi (the City of Studies). The University also has a Choir and its own Orchestra, which actively contributes to the cultural life of the city and receives international acknowledgements on an increasingly frequent basis.

Venue: Sala Napoleonica di Palazzo Greppi

Via S. Antonio, 12

The 18th-century Palazzo Greppi has been designed by Giuseppe Piermarini who built the Scala Theatre in Milan.

Palazzo Greppi commissioned by Count Antonio Greppi, banker and entrepreneur recently nobility, was among the first models of the Milanese neoclassicism.

The staircase and the main floor rooms still retain the neoclassical decoration work of Giocondo Albertolli, Martin Knoller and Andrea Appiani.

After Postdocs in Manchester and Cambridge he became firstly "Research Assistant" in INFM and secondly "Primo Ricercatore" at ISC-CNR where he is still working with many friends and colleagues. Presently he is Full Professor of Physics at IMT Lucca, and a LIMS Fellow. From November 15th 2015 he is the Vice-President of the Complex Systems Society.
Following the financial crisis of 2007-2008, a deep analogy between the origins of instability in financial systems and in complex ecosystems has been pointed out: in both cases, topological features of network structures influence how easy it is for distress to spread within the system. However, in financial network models, the intricate details of how financial institutions interact typically play a decisive role. Hence, a general understanding of precisely how network topology creates instability remains lacking. Here we show how processes that are widely believed to stabilise the financial system, integration and diversification, can actually drive it towards instability, as they contribute to create cyclical structures which tend to amplify financial distress, thereby undermining systemic stability and making large crises more likely. This result holds irrespective of the precise details of how institutions interact, and demonstrates that policy-relevant analysis of the factors affecting financial stability can be carried out while abstracting away from such details.

She received a PhD in Statistical Physics from MIT in 1999, then was a postdoctoral fellow, first in Fundamental Mathematics and Theoretical Physics at Bell Laboratories, and then in the Theory Group at Microsoft Research. Her interdisciplinary work on network theory spans the fields of statistical physics, theoretical computer science and applied math, and has appeared in journals such as Science, PNAS, and Physical Review Letters. She is a Fellow of the American Physical Society, serves on the editorial board of numerous international mathematics and physics journals, has organized key scientific meetings like NetSci 2014, was a member of the World Economic Forum's Global Agenda Council on Complex Systems, and is currently the President of the Network Science Society.
Networks are at the core of modern society, spanning physical, biological and social systems. Each distinct network is typically a complex system, shaped by the collective action of individual agents and displaying emergent behaviors. Moreover, collections of these complex networks often interact and depend upon one another, which can lead to unanticipated consequences such as cascading failures and novel phase transitions. Simple mathematical models of networks can provide important insights into such phenomena. Here we will cover several such models, beginning with control of phase transitions in an individual network then moving on to modeling phenomena in coupled networks, including cascading failures and optimal interdependence.
After a PhD in Physics at ULB, and Post-docs at ULg, UCLouvain and Imperial College, he is currently associate professor in the Department of Mathematics of the University of Namur. His recent research includes the development of algorithms to uncover information in large-scale networks, the study of empirical data in social and biological systems, and the mathematical modelling of human mobility and diffusion on networks. He has authored more than 60 publications in peer-reviewed journals and conference proceedings, with around 5000 citations (Google Citations). He also acts as an academic editor for PLoS One and the European Physical Journal B.
When modelling dynamical systems on networks, it is often assumed that the process is Markovian, that is future states depend only upon the present state and not on the sequence of events that preceded it. Examples include diffusion of ideas or diseases on social networks, or synchronisation of interacting dynamical units. In each case, the dynamics is governed by coupled differential equation, where the coupling is defined by the adjacency matrix of the underlying network. The main purpose of this talk is to challenge this Markovian picture. We will argue that non-Markovian models can provide a more realistic picture in the case of temporal networks where edges change in time, or in situations when pathways can be measured empirically. We will focus on the importance of non-Poisson temporal statistics, and show analytically the impact of burstiness on diffusive dynamics, before turning to applications and incorporating memory kernels in predictive models of retweet dynamics.

The availability of highly detailed data of real-world systems have allowed to study systems that are made up of multiple layers. In this talk, we will revise recent advances on the topic of multilayer networked systems. First, we will discuss how to represent these networks and what kind of metrics are needed to capture the new topological complexity arising from the interdependency of the layers. Secondly, we will also study contagion processes on these topologies and present results regarding the interplay between the critical properties of the system and its structural scales. To summarize, we will discuss possible future directions in this new, but very active field of research.
Eiko Yoneki is a Research Fellow in the Systems Research Group of the University of Cambridge Computer Laboratory. She leads a group called ‘data centric systems and networking’, where current research focuses on the exploration of new abstractions for supporting the design and implementation of robust and heterogeneous large-scale data processing. More information can be found at
The emergence of big data requires fundamental new methodology for data analysis, processing, and information extraction. The main challenge here is to perform efficient and robust data processing, while adapting to the underlying resource availability in a dynamic, large-scale computing environment. I would introduce our recent work on the graph processing that have billion-scale of vertices and edges in a commodity single computer, which requires secondary storage as external memory. Executing algorithms results in access to such secondary storage and performance of I/O takes an important role, regardless of the algorithmic complexity or runtime efficiency of the actual algorithm in use.

Algorithms based on complex networks affect our online experience on a daily basis. One of the most ubiquitous examples of this is the link prediction problem, which is a core part of friend recommendations on social networks like LinkedIn, Facebook, and Pinterest, and also part of broader recommendation systems like personal livestreaming on Periscope or Q&A sites like Quora. Given the success of these systems, and the decade of work on link prediction, it is reasonable to assume that this is a solved problem. Yet no quantitative study has been performed to understand just how successful (or unsuccessful) these algorithms are. Meanwhile, there are plenty of anecdotes online of poor recommendations that represent poor prediction results (e.g. Kashmir Hill, Fusion 2016). In this talk, I will present some of our recent work on taking an empirical view to the well studied problem of link prediction in dynamic networks. We implement and apply 18 link prediction algorithms (some metric-based, some machine learning based) to several traces of detailed network dynamics (Renren, Facebook, YouTube), and evaluate their prediction accuracy. We find that on absolute terms, link prediction accuracy is embarrassingly poor across the board, highlighting the fact that this is still very much an open problem. Machine learning approaches tend to outperform relatively, but are often prohibitively high computation costs. We then propose a novel approach to build "prediction filters” using past patterns in network dynamics. Evaluated on our large datasets, our results significantly boost prediction accuracy across all algorithms.
Professor Estrada has an internationally leading reputation for shaping and developing the study of complex networks. His expertise ranges in the areas of network structure, algebraic network theory, dynamical systems on networks and the study of random models of networks. He has a distinguished track record of high-quality publications, which has attracted more than 8, 500 citations. His h-index (number of papers with at least h citations) is 53. His publications are in the areas of network theory and its applications to social, ecological, engineering, physical, chemical and biological real-world problems. Professor Estrada has published two text books on network sciences both published by Oxford University Press in 2011 and 2015, respectively. He has demonstrated a continuous international leadership in his field where he has been invited and plenary speaker at the major conferences in network sciences and applied mathematics. His research interests include the use of matrix functions; random geometric networks; generalised Laplacian operators for networks; generalised diffusion models for networks; study of indirect peer pressure over consensus dynamics on networks; applications of network sciences to oil and gas exploration; spatial efficiency of networks; Euclidean geometrical embedding of networks, among many others.
Consensus is well documented across the social sciences, with examples ranging from behavioral flocking in popular cultural styles, emotional contagion, collective decision making, pedestrians’ walking behavior, and others. We can model consensus in a social group by encoding the state of each individual at a given time in a vector. The group reaches consensus at when the difference in the “opinions” for every pair of individuals is asymptotically zero, and the collective dynamics of the system is modeled by a diffusion equation dominated by the graph Laplacian. Decisions in groups trying to reach consensus are frequently influenced by a small proportion of the group who guides or dictates the behavior of the entire network. In this situation a group of leaders indicates and/or initiates the route to the consensus, and the rest of the group readily follows their attitudes. The study of leadership in social groups has always intrigued researchers in the social and behavioral sciences. Specifically, the way in which leaders emerge in social groups is not well understood. Leaders may emerge either randomly in response to particular historical circumstances or from the individual having the most prominent position (centrality) in the social network at any time. In this tutorial I will introduce the theoretical model of consensus in a network, for the general case of undirected as well as directed ones. First, I will introduce the mathematical concepts of the model, and show when in every case there is a consensus in the network. I will also introduce some properties of the Laplacian matrix for networks that will help to understand the main results of the model. Then, I will introduce a controllability problem and its solution in networks consisting of leaders and followers. Following this initial part I will how to use Matlab to model a consensus process in a given network (codes will be provided to participants). At this point I will motive the necessity of considering the indirect influence of peers apart from the direct peers pressure. In mathematical terms I will make a generalization of the Laplacian matrix on graphs to consider the k-path Laplacians and their transform. Using this transformed k-path Laplacians I will show how to study a few interesting topics on networks, such as the controllability of networks, the selection of leaders, the diffusion of innovations under direct+indirect peers pressure. Finally, I will prove and illustrate how the consensus and diffusion of innovations can be superdiffusive or ballistic in complex networks under the effect of direct and indirect peers pressure. Some examples, such as diffusion of methods among high schools or the adoption of a biotechnological product among farmers will be used in the tutorial.

Bruno Gonçalves is a Data Science fellow at NYU's Center for Data Science while on leave from a tenured faculty position at Aix-Marseille Université. He has a strong expertise in using large scale datasets for the analysis of human behavior. After completing his joint PhD in Physics, MSc in C.S. at Emory University in Atlanta, GA in 2008 he joined the Center for Complex Networks and Systems Research at Indiana University as a Research Associate. From September 2011 until August 2012 he was an Associate Research Scientist at the Laboratory for the Modeling of Biological and Technical Systems at Northeastern University. Since 2008 he has been pursuing the use of Data Science and Machine Learning to study human behavior. By processing and analyzing large datasets from Twitter, Wikipedia, web access logs, and Yahoo! Meme he studied how we can observe both large scale and individual human behavior in an obtrusive and widespread manner. The main applications have been to the study of Computational Linguistics, Information Diffusion, Behavioral Change and Epidemic Spreading. He is the author of 60+ publications with over 3800+ Google Scholar citations and an h-index of 26. In 2015 he was awarded the Complex Systems Society's 2015 Junior Scientific Award for "outstanding contributions in Complex Systems Science" and he is the editor of the book Social Phenomena: From Data Analysis to Models (Springer, 2015).
The data deluge we currently witnessing presents both opportunities and challenges. Never before have so many aspects of our world been so thoroughly quantified as now and never before has data been so plentiful. On the other hand, the complexity of the analyses required to extract useful information from these piles of data is also rapidly increasing rendering more traditional and simpler approaches simply unfeasible or unable to provide new insights.
In this tutorial we provide a practical introduction to some of the most important algorithms of machine learning that are relevant to the field of Complex Networks in general, with a particular emphasis on the analysis and modeling of empirical data. The goal is to provide the fundamental concepts necessary to make sense of the more sophisticated data analysis approaches that are currently appearing in the literature and to provide a field guide to the advantages an disadvantages of each algorithm.
In particular, we will cover unsupervised learning algorithms such as K-means, Expectation-Maximization, and supervised ones like Support Vector Machines, Neural Networks and Deep Learning. Participants are expected to have a basic understanding of calculus and linear algebra as well as working proficiency with the Python programming language.

For the afternoon session posters should be mounted at 13:30 and removed at 18:15.
Each poster has been assigned a number and must be mounted on the appropriately numbered board. You can check the number by referring to the printed or on-line program.

Poster schedule

The author of the poster is requested to be stand by his/her poster throughout the duration of the scheduled session (please refer to the printed or on-line program for information on when your poster session is scheduled). Authors are encouraged to engage the audiences in technical discussion by making periodic presentations and answering questions.

Oral Presentation

Presentation duration

Presentation time is critical; each paper is allocated 15 minutes for lecture sessions. This time includes setup and questions. We recommend that presentation of your slides should take about 12 minutes, leaving 3 minutes for setup, introduction, summary, and questions from the audience. Recall that COMPLEX NETWORKS is a single track event and there will beplenty of time to discuss your work during the coffee breaks and social events.

Reporting to the session chair

All speakers must report to the session chair at the registration desk before the session at least 30min prior to the beginning of your session.

Uploading your presentation

In order to avoid technical issues, speakers are encouraged to use the laptop provided in the room. Your slides need to be uploaded into the conference computer prior to your presentation. Please bring your materials to the registration desk at least 30min prior to the beginning of your session.
For early morning sessions (Oral O1: Multiplex, Oral O5: Network Analysis and Oral O9: Biological Networks), if possible, upload your session the evening before your presentation.
In order to respect the schedule for uploading your presentation refer to the following table:

For the morning session of November, 2016, please report to the registration desk November 29, 2016 in the afternoon. In case of a positive response, you must ensure long in advance that there are no technical issues. A VGA cable with male connector will be provided for hooking up your laptop. Please ensure to bring the proper adapter that will fit your computer.
