A Star is Born The Étoile project - Enhanced Technology for Open Intelligent Learning Environments

by David Hales

omplex systems science is highly interdisciplinary.

The silo-based education provided by most universities creates scientists expert in one discipline but ignorant of most others. Most PhD programmes require students to learn key ideas from other disciplines relevant to their topic, but knowledge across the community is patchy. This includes basic social science and even the core disciplines of mathematics, statistics, physics and ICT. The Complex Systems Society (CSS) has identified this as a major hindrance to the development of the science.

education. The Open University is a pioneering institution in distance learning and a number of highly innovative and interesting approaches were presented. Étoile aims to draw on the best of this massive resource to provide innovative automated marking schemes (including visual methods and Natural Language Processing techniques based on training data from the massive OU datasets).

The étoile project, which started on 1st March, will address these issues through the development and deployment of an open source, scalable and adaptive online system that will deliver learning resources based on a problem oriented approach.

The basic étoile approach is simple: For a given topic area a set of problems will be set by teachers. Students answer them by searching the web for relevant educational resources e.g. videos, wikipedia articles, blog entries, online books etc. Students submit URL's to found resources with their answers producing an ecology of URL's centred around each problem.

On the third day, an Art-Science workshop, lead by João Fiadeiro (a choreographer), on Socio-Cognitive Stygmery immersed participants in an open improvisation method.

This method uses a form of stygmergic communication, through a shared space and the objects within that space, to trigger an open-ended set of interactions in which the collective product of the participants is not the result of any individual plan or ego. This approach offers the possibility for a revolutionary understanding of human social interaction through stygmergic forms (including those mediated by social media). The workshop produced a very interesting set of outcomes and also led to insights by participants on their styles of creativity and inter-personal interaction.

Etoile comprises three main partners (the Open University in the UK, Fundacao da Faculdade de Ciencias da Universidade de Lisboa in Portugal and Institut des Systèmes Complexes de Paris in France) and ten associated partners from across Europe and beyond.

The kickoff meeting took place at the Open University campus in Milton Keynes over four days from the 9th-12th of March. This started with an initial kickoff session for etiole partners in which the general aims and mission of the project were discussed. Lisbon presented their preprototype etoil system which already provides some of the basic functionality required by the platform.

Following this was a full day of presentations with etoile partners and other Open University faculty members discussing their ongoing work in distance and online

On the fourth and final day the project partners met to discuss the organisational practicalities and agree the

initial phase of work. The basic design philosophy of the project is KISS (Keep it Simple Stupid!). Hence the plan is to start simple (as simple as possible) then release and test early. This allows for rapid cycles of development of both the platform and the content within the platform. To this end it was decided to target two upcoming summer schools that will contain the kinds of students that étoile aims to address:

Overall the kickoff events were highly stimulating and encouraging. The mission of étoile goes far beyond the three year project horizon - Prof. Jeff Johnson (lead partner) stated "I've always passionately believed in truly open education and in breaking down the barriers between disciplines. I believe that étoile could be the spark that helps to transition to a new kind of 21st Century education which is essentially free to all, of high quality and socially useful."

ESSA Summer School on Agent Based Modelling, 18-22th July 2011 Étoile is a Coordination Action funded under the FETASSSYT Summer School on Mathematics, Patras, 18-29th Open Scheme of the European Commission.

July 2011 The project website is at: http://www.etoilecascadesideas.eu/ Simple étoile pilot courses will be produced for students who attend these summer schools and members of étoile will attend the schools to get feedback from those who participated first hand.

fet11 The European Future Technologies Conference and Exhibition 4-6 May 2011 – Budapest, Hungary

T

he European Future Technologies Conference and Exhibition 2011 is the second installment of a new forum dedicated to frontier research in 11 information and communication technologies. fet is a unique conference on visionary, high-risk and long-term research in information science and technology. Featuring an exceptionally broad range of scientific fields the event will seed new ideas across disciplines that will reshape the future.

Keynote Speakers Josh Bongard Title: "How Evolution Shapes the Way Roboticists Think"

necessary for private information to be reflected in prices, but by the same token, random fluctuations in order flow necessarily contribute to the volatility of markets. Our Abstract: Roboticists, by necessity, are keen students of thesis is that the latter contribution is in fact dominant, biology: we hope to create machines that are as agile, resulting in a decoupling between prices and fundamental adaptive and intelligent as the organisms we see around values, at least on short to medium time scales. We argue us. However, roboticists tend to copy the end products of that markets operate in a regime of vanishing revealed evolution (compliant limbs, neural circuits, legged gaits) liquidity, but large latent liquidity, which would explain their rather than evolutionary processes themselves (selection hyper-sensitivity to fluctuations. More precisely, we identify pressures, developmental programs). In this talk I will a dangerous feedback loop between bid-ask spread and show how re-creating evolution in a computer can allow us volatility that may lead to microliquidity crises and price to design robots automatically, rather than trying to build jumps. We discuss several other unstable feedback loops them manually. that should be relevant to account for market crises: imitation, unwarranted quantitative models, pro-cyclical Jean-Philippe Bouchaud regulation, etc.

Title: "The endogenous dynamics of markets: price impact and feedback loops" Rodney Douglas Title: "Constructive Cortical Computation" Abstract: We review the evidence that the erratic dynamics of markets is to a large extent of endogenous origin, i.e.

Abstract: During the past century ever more sophisticated determined by the trading activity itself and not due to the methods have been developed for constructing and rational processing of exogenous news. In order to programming computing and manufacturing machines. understand why and how prices move, the joint However, these methods are essentially forward fluctuations of order flow and liquidity – and the way these processes that depend on intelligent human designers and impact prices – become the key ingredients. Impact is programmers. They stand in stark contrast to Biology's

methods of self-construction used to evoke the flexible information processor that is the mammalian neocortex.

Understanding this radically different approach that uses algorithmic self-programming and construction could have enormous consequences for future computing and manufacturing technologies. In this talk we describe progress towards understanding these principles through detailed simulation of the development of the neocortex.

Artur Ekert Title: "Is the age of computation yet to begin?"

Abstract: The theory of classical universal computation was laid down in 1936, was implemented within a decade, became commercial within another decade, and dominated the world's economy half a century later. This success story relied on the progress in technology. As computers become faster they must become smaller. The history of computer technology has involved a sequence of changes from one type of physical realisation to another from gears to relays to valves to transistors to integrated circuits and so on. The unavoidable step to the quantum level will be one in this sequence; but it promises something more exciting as well. For the first time since the invention of the general purpose computer, a change in underlying hardware can give computers qualitatively new functionality. Quantum theory is already important in the design of microelectronic components. Soon it will be necessary to harness quantum theory, rather than simply take it into account. I will describe our quest to understand quantum theory, our efforts to develop quantum technology to support quantum computation, and our surprise and excitement once we discovered that nature already employs coherent quantum phenomena in biological systems. There is so much potential in this fundamentally new way of harnessing nature that it appears as though the age of computation has not yet even begun!

Abstract: Refractive materials give limited control of light: we can fashion lenses, and construct waveguides, but complete control is beyond simple refracting materials.

Ideally we might wish to channel and direct light as we please just as we might divert the flow of a fluid.

Manipulation of Maxwell!s equation shows that we can achieve just that and metamaterials open the door to this new design paradigm for optics, providing the properties required to give complete control of light. One potential application would be to steer light around a hidden region, creating a cloak of invisibility.

GĂĄbor PrĂłszĂŠky Title: "The (hopefully near) future of human language technologies" Abstract: Today!s language technology applications usually rely on either human-designed rules (used sequentially by computers) or large amount of sequential data, that is, spoken or textual corpora. Today, computer modeling of human language abilities does not use parallel methods. In current natural language processing paradigms the notion of parallelism is almost totally missing. Multi-core processors are nowadays available even in commercial computers. On the other hand, results of brain research are quite far from existing language technology applications. Applying parallelism would lead us to a more realistic architecture for language understanding, with an increased processing speed.

Claire Tomlin Title:"Mathematical models to help understand developmental biology and cancer"

Abstract: As the understanding of cellular regulatory networks grows, system dynamics and behaviors resulting from feedback effects of such systems have proven to be sufficiently complex so as to prevent intuitive understanding. Mathematical modeling in engineering and in physics or chemistry has traditionally sought to Neelie Kroes extrapolate from existing information and underlying Neelie Kroes is no stranger to ICT research and principles to create complex descriptions of various innovation, having been involved in funding such work systems, which could be analyzed or simulated, and from since the early 1980s. which further abstractions could be made.

A Carbon-Cycle Based Stochastic Coevolving agent strategies and network Cellular Automata Climate Model topology for the public goods games Much of human cooperation remains an evolutionary riddle. Coevolutionary public goods games in structured populations are studied where players can change from an unproductive public goods game to a productive one, by evaluating the productivity of the public goods games.

Give postdocs a career, not empty promises Consider the scientific community as an ecosystem, and it is easy to see why postdocs need another path. The system needs only one replacement per lab-head position, but over the course of a 30â&#x20AC;&#x201C;40-year career, a typical biologist will train dozens of suitable candidates for the position. The academic opportunities for a mature postdoc some ten years after completing his or her PhD are few and far between.

On Non-Bayesian Social Learning We study a model of information aggregation and social learning recently proposed by Jadbabaie, Sandroni, and Tahbaz-Salehi, in which individual agents try to learn a correct state of the world by iteratively updating their beliefs using private observations and beliefs of their neighbors. No individual agent's private signal might be informative enough to reveal the unknown state.

Community Detection via SemiSynchronous Label Propagation Algorithms A recently introduced novel community detection strategy is based on a label propagation algorithm (LPA) which uses the diffusion of information in the network to identify communities. Studies of LPAs showed that the strategy is effective in finding a good community structure.

In this article a stochastic cellular automata model is examined, which has been developed to study a "small" world, where local changes may noticeably alter global characteristics. This is applied to a climate model, where global temperature is determined by an interplay between atmospheric carbon dioxide and carbon stored by plant life. The latter can be relased by forest fires, giving rise to significant changes of global conditions within short time.

Sentiment in Twitter events (â&#x20AC;Ś)the results give strong evidence that popular events are normally associated with increases in negative sentiment strength and some evidence that peaks of interest in events have stronger positive sentiment than the time before the peak. It seems that many positive events, such as the Oscars, are capable of generating increased negative sentiment in reaction to them.

Self-organized model of cascade spreading We study simultaneous price drops of real stocks and show that for high drop thresholds they follow a power-law distribution. To reproduce these collective downturns, we propose a minimal self-organized model of cascade spreading based on a probabilistic response of the system elements to stress conditions.
