description: Schwerpunkt des diesjährigen Workshops sind ethische Fragestellungen beim Einsatz quantitativer und qualitativer Methoden der Erforschung und Gestaltung von Mensch-Technik-Interaktion. Im Workshop werden Best Practices erarbeitet und zusammengetragen, die Teilnehmer*innen darin unterstützen, ethischen Aspekten früh und begleitend in der Entwicklung, Erforschung und Evaluation neuer Technik zu begegnen. In kurzen Impulsreferaten wird zunächst das Spektrum aktueller ethischer Herausforderungen in der Mensch-Technik-Interaktion skizziert und erste Lösungsansätze vorgeschlagen. In einem zweiten Teil bearbeiten die Teilnehmer*innen ausgewählte Fallbeispiele verschiedener ethischer Dilemmata in kleineren Teams. Der Problem- und Lösungsraum wird hierbei durch die Methode des World Café sukzessive erweitert. Dadurch wird allen Personen ermöglicht, sich intensiv mit relevanten Themen und Fragestellungen auseinandersetzen zu können. Die erarbeiteten Inhalte werden anschließend zusammengeführt, diskutiert und allen Teilnehmer*innen des Workshops zusammen mit weiteren hilfreichen Materialien zur Verfügung gestellt.

description: Die Diskussion über ethische Aspekte neuer Technologien wird zunehmend breiter geführt. Dennoch werden ethische Herausforderungen im Kontext der Erforschung und Entwicklung von Technologien oftmals nicht genügend oder erst spät berücksichtigt. Praktische Maßnahmen zur Berücksichtigung ethischer Aspekte werden nur vereinzelt entwickelt. Ein Grund dafür kann sein, dass die ethischen Herausforderungen in der Gestaltung, Entwicklung und Erforschung neuer Technik wenig bekannt sind. Dieser Beitrag stellt verschiedene ethische Herausforderungen in den Vordergrund, denen beim Einsatz quantitativer Methoden in der Gestaltung, Entwicklung und Erforschung von neuen Technologien begegnet werden muss. Dabei werden vier zentrale Schwerpunkte thematisiert: Anonymität der Probanden, Archivierung und Vertraulichkeit der Daten, informierte Einwilligung und zuletzt das Kosten-Nutzen-Verhältnis bei der Gewinnung von Daten. Zudem werden praktisch anwendbare Ansätze vorgestellt, die einen Umgang mit den verbundenen Herausforderungen ermöglichen können.

description: We report here non-collinear magnetic configurations in the Heusler alloys Ni2MnGa and Ni2MnAl which are interesting in the context of the magnetic shape memory effect. The total energies for different spin spirals are calculated and the ground state magnetic structures are identified. The calculated dispersion curves are used to estimate the Curie temperature which is found to be in good agreement with experiments. In addition, the variation of the magnetic moment as a function of the spiral structure is studied. Most of the variation is associated with Ni, and symmetry constraints relevant for the magnetization are identified. Based on the calculated results, the effect of the constituent atoms in determining the Curie temperature is discussed.

Constraining Post_Newtonian Parameters With Gravitational Waves

description: We re-express gravitational wave results in terms of post-Newtonian parameters. Using these expressions, and some simplifying assumptions, we compute that in a favorable case, i.e. a ten solar-mass black hole spiraling in to a 10^6 solar-mass black hole, LISA observations will be able to constrain at the 10% level or better a single combination of post-post-Newtonian parameters one order higher than those already constrained by solar system evidence. This significant constraint will be possible even if the signal-to-noise level is so low that the signal can only be found by matched filtering, and hence only deviations between alternate signal interpretations of order one half cycle or more can be detected.

description: We consider several statistical models defined on the Farey fractions. Two of these models may be regarded as "spin chains", with long-range interactions, while another arises in the study of multifractals associated with chaotic maps exhibiting intermittency. We prove that these models all have the same free energy. Their thermodynamic behavior is determined by the spectrum of the transfer operator (Ruelle-Perron-Frobenius operator), which is defined using the maps (presentation functions) generating the Farey "tree". The spectrum of this operator was completely determined by Prellberg. It follows that these models have a second-order phase transition with a specific heat divergence of the form [t (ln t)^2]^(-1). The spin chain models are also rigorously known to have a discontinuity in the magnetization at the phase transition.

description: Learning languages in the form of a tandem program offers learners numerous advantages over individual learning. In order to develop a concept that supports the cooperative work of tandem partners, a qualitative study was conducted using the Design Case Study as a framework for research. The results show the positive impact of cultural exchange and the importance of hearing in language learning. As a result, a concept was developed that promotes cultural exchange and also focuses on hearing. Thus, this paper offers the idea of a technology that assists language learning by listening to the target language from native speakers during a treasure hunt game. Above all, the focus is on cooperation, as riddles have to be solved together by the tandem team.

description: We identify the physics behind the results of recent measurements [W. Kang et al., Nature 403, 59 (2000)] of electron transfer between the edges of two two-dimensional electron systems (2DES). We find that a consistent explanation of all of the observed phenomena is possible if the barrier between the 2DES is surrounded by a strong potential well that supports quantum railroads of edge channels that, in the presence of disorder, exhibit directed localization.

description: Topological properties of Fortuin-Kasteleyn clusters are studied on the torus. Namely, the probability that their topology yields a given subgroup of the first homology group of the torus is computed for Q=1, 2, 3 and 4. The expressions generalize those obtained by Pinson for percolation (Q=1). Numerical results are also presented for three tori of different moduli. They agree with the theoretical predictions for Q=1, 2 and 3. For Q=4 agreement is not ruled out but what seems logarithmic corrections makes it harder to decide.

description: Modern computation relies crucially on modular architectures, breaking a complex algorithm into self-contained subroutines. A client can then call upon a remote server to implement parts of the computation independently via an application programming interface (API). Present APIs relay only classical information. Here we implement a quantum API that enables a client to estimate the absolute value of the trace of a server-provided unitary $U$. We demonstrate that the algorithm functions correctly irrespective of what unitary $U$ the server implements or how the server specifically realizes $U$. Our experiment involves pioneering techniques to coherently swap qubits encoded within the motional states of a trapped \Yb ion, controlled on its hyperfine state. This constitutes the first demonstration of modular computation in the quantum regime, providing a step towards scalable, parallelization of quantum computation.

Two Essays in Empirical Asset Pricing
Creators: name: Nardi, Flavio
Publisher: name: The Australian National University
Year: 2017
Subjects: Empirical asset pricing

description: This thesis includes two research papers in the area of empirical asset pricing. In the first research paper titled "Option implied moments and risk aversion", under reasonable assumptions, I provide empirical evidence that index options implied higher moments can predict the index returns and Sharpe ratio. Specifically, I present a method to recover option implied subjective moments of the S\&P500 index under the assumption of no arbitrage and logarithmic utility. This result adds further evidence to the extensive finance literature that claims that market returns are predictable. In the second research paper titled "Expected returns: systematic risk or firm characteristics" I provide empirical evidence that expected returns can be viewed as determined by the exposure of firm returns to systematic factors that are based on firm characteristics, and not directly to the cross--sectional differences in the firm characteristics. This result addresses an ongoing debate within the empirical asset pricing literature as to whether the cross--section of expected returns is "explained" by the loadings to systematic factors or by differences in firm characteristics. The evidence I provide supports the loading to systematic factors story, consistent with the consumption asset pricing model.

Visual Arts in preschools

description: This study investigates whether the anxiety evidenced in the National Review of Visual Education (NRVE) (Davis, 2008), regarding generalist primary teachers, also impacts on preschool teachers’ delivery of Visual Arts. Taking a mixed-methods approach the study is organised in three interlocking stages, the first two of which seek to explore, at the preschool level, whether the findings of previous studies are replicated in preschools. The third and final stage, however, is designed to take the issue beyond previous studies to consider what might be done to address Arts anxiety at a local level while utilising only existing resources. Stage One uses both quantitative and qualitative questions to survey a sample of preschool teachers in Canberra, in the Australian Capital Territory (ACT) in relation to their teaching, especially in the learning area of Visual Arts. The sample was obtained by the snowball method: 50 requests for participation in a confidential survey were dispatched by the researcher and 26 completed surveys were returned. Results from the survey showed that this, albeit limited, sample of preschool teachers also reported experiencing Art anxiety and a lack of confidence in teaching Visual Arts. The final question of the confidential survey invited respondents to indicate willingness to participate in Stage Two and, if so, to provide contact details. Ten teachers were then selected at random from the 25 who indicated willingness to proceed to Stage Two. This second stage was a 30 minute individual interview with questions designed to allow teachers to expand upon their survey responses and scope concerns and issues. All ten teachers who were interviewed wished to be selected to continue to Stage Three, an individualized professional learning experience (after Rogers (1969)), offered over three months in their place of work. Selection for Stage Three was based on geographical situation as well as level of teaching experience and preschool type to maximise the diversity of the group. Each preschool teacher worked with the researcher for up to three months on a trajectory of her own choice and, consistent with the Rogerian learning framework, evaluated her own progress towards self-chosen goals. Using journal documentation and audio records of meetings with the researcher a narrative of each teacher’s learning journey was charted. All preschool teachers reported increased confidence and enhanced direction in their teaching of Visual Arts. The implications of the study for professional learning and further research are explored within the context of this small-scale study within a single location in Canberra, Australia. The study has implications for individualized professional development in preschools: The collaborative model developed and trialled with preschool teachers has been recognised as having potential for wider and immediate application.

description: TensorFlow Eager is a multi-stage, Python-embedded domain-specific language for hardware-accelerated machine learning, suitable for both interactive research and production. TensorFlow, which TensorFlow Eager extends, requires users to represent computations as dataflow graphs; this permits compiler optimizations and simplifies deployment but hinders rapid prototyping and run-time dynamism. TensorFlow Eager eliminates these usability costs without sacrificing the benefits furnished by graphs: It provides an imperative front-end to TensorFlow that executes operations immediately and a JIT tracer that translates Python functions composed of TensorFlow operations into executable dataflow graphs. TensorFlow Eager thus offers a multi-stage programming model that makes it easy to interpolate between imperative and staged execution in a single package.

A kingdom of words : Minangkabau sovereignty in Sumatran history

Year: 1993
Subjects: subject: Authority
subject: Minangkabau (Indonesian people) Communication
subject: Dutch HistoryIndonesia Sumatra
subject: Sumatra (Indonesia) Kings and rulers
subject: Sumatra (Indonesia) Social life and customs

description: The thesis is concerned with the nature of royal authority in the Sumatran inland kingdom of Minangkabau in the seventeenth and eighteenth centuries. It takes as its point of departure the problem posed by early European perceptions of that authority. European contacts were with the coasts of Sumatra. The Minangkabau heartland, behind its mountain barrier, appeared remote and inaccessible. The Dutch, following on the heels of the Portuguese in the seventeenth century, were contemptuous of the rulers of Minangkabau, describing them as powerless - as kings in word only and not in deed. This view has been repeated by many subsequent observers, some of whom have spoken of the sacral or the symbolic nature of Minangkabau claims. The thesis will argue that the Minangkabau kings were far from being mere figureheads or possessors of merely symbolic authority. They provided a focus for unity extending far beyond the inland centre of the kingdom and were a means of mobilizing a supra-nagari identity. The use of the king’s name by his subjects in the rantau, royal intervention in local movements of resistance to the Dutch and the creation of an extended communications network combined to indicate the presence of genuine political substance. The Dutch had to come to terms with that force and themselves found it useful, on occasion, to rely on the king’s name. Attention is given to the details of Dutch contacts with coastal regions, to their initial contacts with the inland court itself and to the development of movements of resistance to the VOC. The cultural encounter embodied in these early contacts is approached through a study of the VOC archives which are read for the light they throw on Dutch perceptions and expectations as well as for the events they report. Central to the argument of the thesis is the view that the king’s power lay, to a considerable extent in the language of royal communication and in the substance given by his subjects to the signs of his authority. Attention is given in detail, therefore, to a range of royal letters. Many of these are to be found in Dutch translation in the archives of the VOC. These have been studied in the context of a corpus of manuscript Malay letters from the nineteenth century which were discovered in the course of research for the thesis. The study of the words and the format of these letters enables conclusions to be drawn about Minangkabau perceptions of authority and about its substance. A semiotic approach to the communicative process rather than one which focusses on the institutional structure of the Minangkabau state, it is argued, can throw significant light on the meaning of Minangkabau kingship during this period.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Stability criteria of nearly extreme black holes in the perturbations level is one of the interesting issues in gravitational systems. Considering the nearly extreme conformal-de Sitter black holes, in this paper, we obtain an exact relation for the quasinormal modes of scalar perturbations. As for stability criteria, we find a lower bound on the event horizon radius which is corresponding to an upper bound on the value of the quasinormal frequencies. In addition, we show that the asymptotic behavior of quasinormal modes gives highly damped modes which is important due to possible connection between their real part and the Barbero-Immirzi parameter. We also obtain the Lyapunov exponent and the angular velocity of unstable circular null geodesics. Finally, we examine the validity of the relation between calculated quasinormal modes and unstable circular null geodesics.

description: The discovery of a SM Higgs boson at the LHC brought about great opportunity to investigate the feasibility of a Circular Electron Positron Collider (CEPC) operating at center-of-mass energy of $\sim 240$ GeV, as a Higgs factory, with designed luminosity of about $2\times 10^{34}cm^{-2}s^{-1}$. The CEPC provides a much cleaner collision environment than the LHC, it is ideally suited for studying the properties of Higgs boson with greater precision. Another advantage of the CEPC over the LHC is that the Higgs boson can be detected through the recoil mass method by only reconstructing Z boson decay without examining the Higgs decays. In Concept Design Report(CDR), the circumference of CEPC is 100km, with two interaction points available for exploring different detector design scenarios and technologies. The baseline design of CEPC detector is an ILD-like concept, with a superconducting solenoid of 3.0 Tesla surrounding the inner silicon detector, TPC tracker detector and the calorimetry system. Time Projection Chambers (TPCs) have been extensively studied and used in many fields, especially in particle physics experiments, including STAR and ALICE. The TPC detector will operate in continuous mode on the circular machine. To fulfill the physics goals of the future circular collider and meet Higgs/$Z$ run, a TPC with excellent performance is required. We have proposed and investigated the ions controlling performance of a novel configuration detector module. The aim of this study is to suppress ion backflow ($IBF$) continually. In this paper, some update results of the feasibility and limitation on TPC detector technology R$\&$D will be given using the hybrid gaseous detector module.

On a scalar theory of gravitation

Publisher: name: arXiv
Year: 2001
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: That preferred-frame theory accounts for special relativity and reduces to it if the gravitation field cancels. Starting from an interpretation of gravity as a pressure force, it is based on just one scalar field. This scalar gives the relation between the flat "background" metric and the curved "physical" metric, due to an equivalence principle between the absolute effects of motion and gravitation. The scalar is also a potential for the gravity acceleration vector. Motion is governed by an extension of the special-relativistic form of Newton's second law. This provides a new equation for continuum dynamics, that gives the gravitational modification of Maxwell's equations, consistent with photon dynamics. The same effects on light rays as in GR are predicted at the post-Newtonian approximation (PNA). An asymptotic PNA is being studied, in order to build a consistent celestial mechanics in the theory. The cosmic acceleration is predicted and nonsingular cosmological models are obtained.

description: The density matrix renormalization group method for ladders works much more efficiently with open boundary conditions. One consequence of these boundary conditions is groundstate charge density oscillations that often appear to be nearly constant in magnitude or to decay only slightly away from the boundaries. We analyse these using bosonization techniques, relating their detailed form to the correlation exponent and distinguishing boundary induced generalized Friedel oscillations from true charge density waves. We also discuss a different approach to extracting the correlation exponent from the finite size spectrum which uses exclusively open boundary conditions and can therefore take advantage of data for much larger system sizes. A general discussion of the Friedel oscillation wave-vectors is given, and a convenient Fourier transform technique is used to determine it. DMRG results are analysed on Hubbard and t-J chains and 2 leg t-J ladders. We present evidence for the existence of a long-ranged charge density wave state in the t-J ladder at a filling of n=0.75 and near J/t \approx 0.25.

description: Epidemic control may be hampered when the percentage of asymptomatic cases is high. To estimate whether test positivity may assist in policy-making, it was explored in the first 60 to 90 epidemic days in six Latin American countries that reported their first COVID-19 case between February and March, 2020: Argentina, Bolivia, Chile, Cuba, Mexico, and Uruguay. Test positivity (TP) is the percentage of test-positive individuals recorded on a given day out of all individuals tested on the same day. The epidemic data of the country infected last (Uruguay) was first analyzed to evaluate TP as well as: (i) the daily ratio of secondary over primary infections (apparent reproductive ratio or ARR); (ii) tests conducted per million inhabitants (TPMI), (iii) the temporal data on the number of active cases (all test-positive cases minus deaths and recovered patients), and (iv) that of recovered patients. Later, significant patterns identified in the first step were assessed in the six countries. The Uruguayan data indicated that (i) TP was positively correlated with the ARR (r=.92, p<0.01); (ii) TP informed more than the ARR: while major data departures revealed by the ARR were also detected by TP, TP exhibited patterns not shown by ARR; and (iii) three temporal stages were observed, which differed from one another in both TP and TPMI medians (P<0.01) and, together, revealed a negative relationships between TPMI and TP. The six Latin American countries showed that TP was positively correlated with deaths/million inhabitants or DMI (r=.62, p<0.01). The temporal analysis of policies revealed four patterns: (1) low testing and high DMI, (2) high testing and low DMI; (3) an intermediate pattern, and (4) high testing and high DMI (where isolation was not pursued). Findings support the hypothesis that test positivity may inform as much as, if not more than classic metrics, such as the TPMI. If complemented with high-resolution geographical data, these indicators could inform policy-makers when and where epidemic control measures are or are not successful.

description: Die Forschung im Bereich der Mensch-Computer-Interaktion (HCI) nutzt ein zunehmend breiter werdendes Methodenspektrum für eine sich immer weiter auffächernde Bandbreite von Forschungsfeldern. Zahlreiche Studien verlassen für die Datenerhebung den vertraut-kontrollierbaren Kosmos von Laboren und Versuchsständen, um stattdessen im Feld mehr über das Verhalten einer NutzerInnengruppe im „natürlichen“ Kontext zu erfahren. Für jede Forschung gelten unabhängig von Feld und Methode die forschungsethischen Grundprinzipien der Freiwilligkeit, Benefizienz und Gerechtigkeit. Um das Freiwilligkeits-Prinzips in der Forschungspraxis zu gewährleisten, stellt der Einsatz von Einverständniserklärungen als informierte Zustimmung bzw. Informed Consent (IC) einen kritischen Punkt für jedes Studiendesign dar. Für viele qualitative Methoden besteht in Bezug auf das Gebot des IC in der HCI Forschung eine direkte Analogie zu der etablierten Ethikpraxis für quantitative Methoden. Die Ethnografie nimmt hier jedoch eine gewisse Sonderstellung ein. Begründet in ihrem methodischen Kernansatz der in-situ Beobachtung stellt insbesondere das Thema IC immer wieder eine ethische und forschungspraktische Herausforderung dar, da es bei einer feldbasierten und damit interaktionsoffenen Forschung schwieriger ist festzustellen, welche der beteiligten Personen als direkte ForschungsteilnehmerInnen zu konzeptualisieren sind bzw. von welchen Personen ein IC in welcher Form gebraucht wird. Dieser Artikel rückt die Frage nach einem sinnvollen und ethisch korrekten Einsatz von IC in ethnografischen Studien im HCI Bereich ins Zentrum der Betrachtung. Mit der Skala der situationsangemessenen Privatsphärenerwartung und IC (SPIC-Skala) wird ein praxistauglicher Lösungsansatz vorgestellt, der sich bereits in zahlreichen Forschungsprojekten im HCI Kontext bewährt hat. Kernargument der SPIC-Skala ist, dass Forschende sich in ihren IC Maßnahmen an den situationsabhängigen Privatsphärenerwartungen von beteiligten Personen orientieren sollten. Eine solche Wahrung der Privatsphärenerwartungen sehen wir als forschungspraktische Operationalisierung des Freiwilligkeits-Prinzips in offenen Forschungssituationen. Dass ein solches Schema jedoch kein „Freifahrtschein“ sein kann, und immer wieder aufs Neue für den eigenen Kontext geprüft werden muss, wird in einem abschließenden Fazit diskutiert.

description: Rossby modes are the oscillations in a rotating fluid, whose restoring force is the Coriolis force. They provide an additional diagnostic to understand the rotation of stars, which complicates asteroseismic modelling. We report 82 $γ$\,Doradus stars for which clear period spacing patterns of both gravity and Rossby modes have been detected. The period spacings of both show a quasi-linear relation with the pulsation period but the slope is negative for the gravity modes and positive for the Rossby modes. Most Rossby modes have $k=-2, m=-1$. For only one star a series of $k=-1,m=-1$ modes is seen. For each pattern, the mean pulsation period, the mean period spacing, and the slope are measured. We find that the slope correlates with the mean period for Rossby mode patterns. The traditional approximation of rotation is used to measure the near-core rotation rate, assuming the star rotates rigidly. We report the near-core rotation rates, the asymptotic period spacings, and the radial orders of excited modes of these 82 main-sequence stars. The near-core rotation rates lie between $0.6\,\mathrm{d^{-1}}$ and $2.3\,\mathrm{d^{-1}}$. Six stars show surface rotation modulations, among which only KIC\,3341457 shows differential rotation while the other five stars have uniform rotations. The radial orders of excited modes show different distributions for the dipole and quadrupole gravity modes versus the Rossby modes.

description: We carry out a self-consistent analytical theory of unipolar current and noise properties of metal-semiconductor-metal structures made of highly resistive semiconductors in the presence of an applied bias of arbitrary strength. By including the effects of the diffusion current we succeed to study the whole range of carrier injection conditions going from low level injection, where the structure behaves as a linear resistor, to high level injection, where the structure behaves as a space charge limited diode. We show that these structures display shot noise at the highest voltages. Remarkably the crossover from Nyquist noise to shot noise exhibits a complicate behavior with increasing current where an initial square root dependence (double thermal noise) is followed by a cubic power law.

description: Recently an inflationary potential yielding power spectra characterized by a scale-invariant tensorial spectral index and a scale-dependent scalar spectral index was introduced. We analize here the implications that this potential could have for the large-scale structure formation in the multiverses scenario of eternal inflation.

description: Im Bereich der Mensch-Technik-Interaktion (MTI) hat sich der Menschzentrierte Gestaltungsprozess (Human Centred Design Process, HCD) als Vorgehen für die bedarfs- und bedürfnisgerechte Technikentwicklung etabliert. Das Konzept der Personalisierung stößt in der Produktentwicklung zunehmend auf Interesse, wobei jedoch unklar bleibt, wie die Entwicklung personalisierter Systeme methodisch unterstützt werden kann. Wir schlagen ein Rahmenmodell vor (HCD4Personalization), das den HCD methodisch erweitert, um Systeme zu entwickeln, deren Interaktionsmechanismen an individuelle Eigenschaften der Nutzenden angepasst werden können. Der HCD4Personalization orientiert sich an den fünf Phasen des klassischen HCD und beschreibt welche personalisierungsbezogenen Fragestellungen in der jeweiligen Phase über das klassische Vorgehen hinaus berücksichtigt werden sollten. Es spezifiziert außerdem mögliche Ergebnisse jeder Phase und wie mit diesen im weiteren Prozessverlauf weitergearbeitet wird. Der HCD4Personalization bietet hierbei ein generisches Vorgehen, dass auf die Entwicklung unterschiedlichster Produkte und Dienstleistungen angewandt werden kann.

description: Designing plausible network models typically requires scholars to form a priori intuitions on the key drivers of network formation. Oftentimes, these intuitions are supported by the statistical estimation of a selection of network evolution processes which will form the basis of the model to be developed. Machine learning techniques have lately been introduced to assist the automatic discovery of generative models. These approaches may more broadly be described as "symbolic regression", where fundamental network dynamic functions, rather than just parameters, are evolved through genetic programming. This chapter first aims at reviewing the principles, efforts and the emerging literature in this direction, which is very much aligned with the idea of creating artificial scientists. Our contribution then aims more specifically at building upon an approach recently developed by us [Menezes \& Roth, 2014] in order to demonstrate the existence of families of networks that may be described by similar generative processes. In other words, symbolic regression may be used to group networks according to their inferred genotype (in terms of generative processes) rather than their observed phenotype (in terms of statistical/topological features). Our empirical case is based on an original data set of 238 anonymized ego-centered networks of Facebook friends, further yielding insights on the formation of sociability networks.
