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.

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, i.e.market 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.

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.

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.

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.

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.
