GP-HD: Using Genetic Programming to Generate Dynamical Systems Models for Health Care

The huge wealth of data in the health domain can be exploited to create models that predict development of health states over time. Temporal learning algorithms are well suited to learn relationships between health states and make predictions about their future developments. However, these algorithms: (1) either focus on learning one generic model for all patients, providing general insights but often with limited predictive performance, or (2) learn individualized models from which it is hard to derive generic concepts. In this paper, we present a middle ground, namely parameterized dynamical systems models that are generated from data using a Genetic Programming (GP) framework. A fitness function suitable for the health domain is exploited. An evaluation of the approach in the mental health domain shows that performance of the model generated by the GP is on par with a dynamical systems model developed based on domain knowledge, significantly outperforms a generic Long Term Short Term Memory (LSTM) model and in some cases also outperforms an individualized LSTM model

Values in the EUÕs Neighbourhood Policy: Political Rhetoric or Reflection of a Coherent Policy?

The European Neighbourhood Policy (ENP) is often justified by references to its unprecedented emphasis on the Òcommitment to shared valuesÓ in future EU relations with its vicinity. Few attempts have been made, however, to critically reflect on the Òvalues dimensionÓ of the ENP. This article examines if the ENP can be sufficiently justified on the basis of the political values it embodies: It explores the extent to which the declared commitment to values in the ENP is based on a wider consensus at the EU-level; the changing emphasis on Òshared valuesÓ in the policy over time; and the degree to which the ENP adds to institutionalising political values in future EU relations with its neighbours.EU Foreign Policy, European Neighbourhood Policy, EuropeanNeighbourhood and Partnership Instrument, European Values

Инновационные подходы в совершенствовании рекламной деятельности

Традиционные подходы к совершенствованию рекламной деятельности ориентированы на ее понимание лишь как элемента маркетинга. В то же время, как показывает опыт, решить эту проблему без признания рекламной деятельности как многофакторной комплексной системы невозможно. С учетом ориентации на системность подхода в статье предлагается использование математического аппарата, учитывающего возможности многовероятного подхода к выработке рекламной политики.Traditional approaches to perfection of advertising activity are focused on its understanding only as an element of marketing.The same time as experience shows it is impossible to solve this problem without a recognition of advertising activity as a multifactorial complex system. In the point view of orientation to system approach in the article it is offered the using of the mathematical methods taking into attention to the opportunities of the multiprobable approach to the development of an advertising policy

Polynomial inequalities representing polyhedra

Our main result is that every n-dimensional polytope can be described by at most (2n-1) polynomial inequalities and, moreover, these polynomials can explicitly be constructed. For an n-dimensional pointed polyhedral cone we prove the bound 2n-2 and for arbitrary polyhedra we get a constructible representation by 2n polynomial inequalities.Comment: 9 page

Projects, careers and resistances in hotels

The hotel industry rhythms appear as a hindrance to staff loyalty and female careers development. However, two hotel networks of the Accor group, Etap Hotel and Formule 1 stand out from this general pattern with a presence of female managers (38% of managers). This case incites to wonder about career ladders within these budget hotel chains. Are the assets and the obstacles combined in the same way for men and for women? Which views have the employees and managers about their jobs, their working conditions and their plans for the future ?career ; female career ; hotel industry ; France

Formal Interpretation of a Multi-Agent Society As a Single Agent

In this paper the question is addressed to what extent the collective processes in a multi-agent society can be interpreted as single agent processes. This question is answered by formal analysis and simulation. It is shown for an example process how it can be conceptualised, formalised and simulated in two different manners: from a single agent (or cognitive) and from a multi-agent (or social) perspective. Moreover, it is shown how an ontological mapping can be formally defined between the two formalisations, and how this mapping can be extended to a mapping of dynamic properties. Thus it is shown how collective behaviour can be interpreted in a formal manner as single agent behaviour.Collective Intelligence, Simulation, Logical Formalisation, Single Vs. Multi-Agent Behaviour

Social Simulation and Analysis of the Dynamics of Criminal Hot Spots

Within the field of Criminology, the spatio-temporal dynamics of crime are an important subject of study. In this area, typical questions are how the behaviour of offenders, targets, and guardians can be explained and predicted, as well as the emergence and displacement of criminal hot spots. In this article we present a combination of software tools that can be used as an experimental environment to address such questions. In particular, these tools comprise an agent-based simulation model, a verification tool, and a visualisation tool. The agent-based simulation model specifically focuses on the interplay between hot spots and reputation. Using this environment, a large number of simulation runs have been performed, of which results have been formally analysed. Based on these results, we argue that the presented environment offers a valuable approach to analyse the dynamics of criminal hot spots.Agent-Based Modelling, Criminal Hot Spots, Displacement, Reputation, Social Simulation, Analysis
