2016-05-23, Complex networks, data minign and causality
During the last weeks, I've published two papers that may be of interest to all complex systems researchers - and beyond.
The first one is a large review on the combined use of complex network theory and data mining. Not only do complex network analysis and data mining share the same general goal, that of extracting information from complex systems to ultimately create a new compact quantifiable representation, but they also often address similar problems too. In spite of this, a surprisingly low number of researchers turn out to resort to both methodologies, and one may then be tempted to conclude that these two fields are either largely redundant or totally antithetic. In this review, we challenge this perception, show how this state of affairs should be put down to contingent rather than conceptual differences, and that these two fields can in fact advantageously be used in a synergistic manner. The review starts by presenting an overview of both fields, and by illustrating some of their fundamental concepts. A variety of contexts in which complex network theory and data mining have been used in a synergistic manner are then presented. Finally, all discussed concepts are illustrated with worked examples through a series of hands-on sections, which we hope will help the reader to put these ideas in practice. If you ever wonder how a real-world problem can be tackled by these two techniques, you should definitively read this review!
The second paper tackles a rather disturbing problem. We know that correlation is not causality - or, at least, you should know it! Following this idea, many causality metrics have been proposed in the literature, all sharing a same drawback: they are defined for time series. In other words, the system (or systems) under analysis should display a time evolution. Associating causality to the temporal domain is intuitive, due to the way the human brain incorporates time into our perception of causality; nevertheless, such association creates some rather important problems. For instance, suppose one is trying to detect if there is a causality relation between the workload of an ATC controller, and the appearance of loss of separation events. These events are only defined at one point in time: one can detect an instance of a loss of separation, and check the corresponding workload; afterwards, do the same for another event; and so forth. At the end, the researcher would get two vectors of features, which do not encode any temporal evolution - in other words, consecutive values are not correlated. So, in this situation, how can we detect if a true causality (and not just a correlation) is present? In this work I propose a novel metric able to detect causality within static data sets, by analysing how extreme events in one element correspond to the appearance of extreme events in a second one. The metric is able to detect non-linear causalities; to analyse both cross-sectional and longitudinal data sets; and to discriminate between real causalities and correlations caused by confounding factors.
If you are interested in these ideas, feel free to have a look at these two papers:

2015-04-24, Call for Papers, Complexity Science and Transportation Systems ‘15.
Satellite Meeting at the Lipari School on Complex Systems 2015, Lipari Island, July 12th-18th 2015. Following the events organized at the ECCS ’11 in Vienna, ECCS ’12 in Brussels ECCS ’13 in Barcelona and ECCS ’14 in Lucca, we announce the Call for Papers for a half-day Satellite Meeting “Complexity Science and Transportation Systems” within the Lipari summer school on Complex Systems. The aim of this Satellite Meeting is to create a space for exchanging state-of-the-art results and ideas about (i) how different Complex Systems tools such as complex networks, percolation theory, self-organized criticality or agent based modeling can be used to understand the internal dynamics of transportation systems, (ii) how to model the relationships between different transportation modes, and (iii) how to improve efficiency and performance of such systems. More information can be found here.
