Résumé :

This paper discusses prominent examples of what we call “algorithmic anxiety” in artworks engaging with algorithms. In particular, we consider the ways in which artists such as Zach Blas, Adam Harvey and Sterling Crispin design artworks to consider and critique the algorithmic normativities that materialize in facial recognition technologies. Many of the artworks we consider center on the face, and use either camouflage technology or forms of masking to counter the surveillance effects of recognition technologies. Analyzing their works, we argue they on the one hand reiterate and reify a modernist conception of the self when they conjure and imagination of Big Brother surveillance. Yet on the other hand, their emphasis on masks and on camouflage also moves beyond such more conventional critiques of algorithmic normativities, and invites reflection on ways of relating to technology beyond the affirmation of the liberal, privacy-obsessed self. In this way, and in particular by foregrounding the relational modalities of the mask and of camouflage, we argue academic observers of algorithmic recognition technologies can find inspiration in artistic algorithmic imaginaries.

Résumé :

Datafication and the use of algorithmic systems increasingly blur distinctions between policy fields. In the financial sector, for example, algorithms are used in credit scoring, money has become transactional data sought after by large data-driven companies, while financial technologies (FinTech) are emerging as a locus of information warfare. To grasp the context specificity of algorithmic governance and the assumptions on which its evaluation within different domains is based, we comparatively study the sociotechnical imaginaries of algorithmic governance in European Union (EU) policy on online disinformation and FinTech. We find that sociotechnical imaginaries prevalent in EU policy documents on disinformation and FinTech are highly divergent. While the first can be characterized as an algorithm-facilitated attempt to return to the presupposed status quo (absence of manipulation) without a defined future imaginary, the latter places technological innovation at the centre of realizing a globally competitive Digital Single Market.

Résumé :

Through an array of technological solutions and awareness-raising initiatives, civil society mobilizes against an onslaught of surveillance threats. What alternative values, practices, and tactics emerge from the grassroots which point toward other ways of being in the datafied society? Conversing with critical data studies, science and technology studies, and surveillance studies, this article looks at how dominant imaginaries of datafication are reconfigured and responded to by groups of people dealing directly with their harms and risks. Building on practitioner interviews and participant observation in digital rights events and surveying projects intervening in three critical technological issues of our time—the challenges of digitally secure computing, the Internet of Things, and the threat of widespread facial recognition—this article investigates social justice activists, human rights defenders, and progressive technologists as they try to flip dominant algorithmic imaginaries. In so doing, the article contributes to our understanding of how individuals and social groups make sense of the challenges of datafication from the bottom-up.

Résumé :

In this article, I report from an ethnographic investigation into young adult users of the popular short-video app TikTok. More specifically, I discuss their experience of TikTok’s algorithmic content feed, or so-called “For You Page.” Like many other personalized online environments today, the For You Page is marked by the tension of being a mechanism of digital surveillance and affective control, yet also a source of entertainment and pleasure. Focusing on people’s sense-making practices, especially in relation to stories about the TikTok algorithm, the article approaches the discursive repertoire that underpins people’s negotiation of this tension. Doing so, I theorize the role and relevance of “stories about algorithms” within the context of algorithmic imaginaries as activating users in sense-making processes about their algorithmic entanglements.

Résumé :

How does a practice of mimesis — as dramatic enactment in a live-action role-playing game (LARP) — relate to the design of artificial intelligence systems? In this article, I trace the contours of a mimetic method, working through an auto-ethnographic approach in tandem with new materialist theory and in conjunction with recent tendencies in design research to argue that mimesis carries strong potential as a practice through which to encounter, negotiate, and design with artificial intelligence imaginaries. Building on a new materialist conception of mimesis as more-than-human sympathy, I illuminate how LARP that centered on the enactment of a fictional artificial intelligence system sustained an encounter with artificial intelligence imaginaries. In what can be understood as a decidedly mimetic way of doing ethnography of algorithmic systems, I argue that we need to consider the value of mimesis — understood as a practice and a method — as a way to render research into artificial intel- ligence imaginaries.

Résumé :

The current proliferation of algorithmic agents (bots, virtual assistants, therapeutic chatbots) that boast real or exaggerated use of AI produces a wide range of interactions between them and humans. The ambiguity of various real and perceived agencies that arises in these encounters is usually dismissed in favour of designating them as technologically or socially determined. However, I argue that the ambiguity brought forth by different opacities, complexities and autonomies at work renders the imaginaries of these algorithms a powerful political and cultural tool. Following approaches from critical theory, posthumanities, decolonial AI and feminist STS that have already approached the boundary between human and non-human productively, it becomes possible to consider technological agents as algorithmic Others, whose outlines, in turn, reveal not only human fears and hopes for technology, but also what it means to be “human” and how normative “humanness” is constructed. Drawing on the work of Antoinette Rouvroy on algorithmic governmentality and Elizabeth A. Povinelli’s ideas of geontology and geontopower, this paper offers a conceptual model of procedural animism in order to rethink the questions of governance and relationality unfolding between humans and non-humans, between the do- mains of “Life” and “Non-Life”. In doing so, it illuminates a series of processes and procedures of (de)humanisation, image politics and figuration in the context of everyday communication and politically engaged art. Ultimately, what is at stake is a potential to consider alternative conceptions of algorithmic Others, ones that might be differently oriented within our environmental, political and cultural futures.

Résumé :

Algorithmic systems that recommend content often lack transparency about how they come to their suggestions. One area in which recommender systems are increasingly prevalent is online news distribution. In this paper, we explore how a lack of transparency of (news) recommenders can be tackled by involving users in the design of interface elements. In the context of automated decision-making, legislative frameworks such as the GDPR in Europe introduce a specific conception of transparency, granting 'data subjects' specific rights and imposing obligations on service providers. An important related question is how people using personalized recommender systems relate to the issue of transparency, not as legal data subjects but as users. This paper builds upon a two-phase study on how users conceive of transparency and related issues in the context of algorithmic news recommenders. We organized co-design workshops to elicit participants' 'algorithmic imaginaries' and invited them to ideate interface elements for increased transparency. This revealed the importance of combining legible transparency features with features that increase user control. We then conducted a qualitative evaluation of mock-up prototypes to investigate users' preferences and concerns when dealing with design features to increase transparency and control. Our investigation illustrates how users' expectations and impressions of news recommenders are closely related to their news reading practices. On a broader level, we show how transparency and control are conceptually intertwined. Transparency without control leaves users frustrated. Conversely, without a basic level of transparency into how a system works, users remain unsure of the impact of controls.

Résumé :

Blockchain is a distributed ledger technology arising from the world of Bitcoin and cryptocurrencies, which has been advocated as a disruptive and revolutionary innovation. Because of the peculiarity of its architectural technicalities, in fact, blockchain technology has seen a growth of its social applications in recent years and has gained the attention of a large variety of actors, interested in its potentiality for entering the social domain and enabling the creation of decentralized, horizontal and peer-to-peer networks. This thesis aims at studying the visions of the world surrounding the implementation of blockchain technology, by analyzing narratives and discourses emerging among those who create and use it. Based on a critical understanding of algorithms and technology as non-neutral and as subject to bias and pitfalls, this work focuses on the sociological and political significance of imagining a technology for the social and public good, posing a particular attention to developers and digital entrepreneurs’ understanding of sociality. Drawing on a one-year multi-sited fieldwork in Milan, London, Tallinn and the online sphere, this work combines a theoretical analysis with ethnographical insights that arise from participant observation and a number of interviews with individuals from the blockchain scene. By relying on a qualitative study that aims at researching the values and aspirations that are encoded in technology, I argue that blockchain social imaginary is embedded in neoliberal, technocratic visions of the world and that blockchainers’ understanding of society and social relations becomes tokenized and subject to mathematical simplifications. My argument develops in three phases: firstly, I show how blockchain works as a floating signifier and thus could be interpreted as a populist buzzword; secondly, I argue that blockchain is surrounded by regimes of truth regarding its disruptive potential that overlooks social dynamics and logics; thirdly, I show that blockchainers’ understanding of social good is based on metrics and competition, thereby reinforcing a number of neoliberal myths associated with the Californian Ideology. By showing the importance of integrating more sociological perspectives to the study of digital technology’s potential, this work exits the financial and informatics domain, merging previous studies on blockchain with a human-rights based approach that ground its roots on social justice theory.

Estudiem les dinàmiques dels actes d'imaginació des d'un punt de vista filosòfic, formal i aplicat.

Tot analitzant les propietats de la lògica, veiem que la manera com els mons imaginaris es desenvolupen està massa simplificada. Una anàlisi més profunda porta a la definició d¿una nova teoria especialment dissenyada per a les dinàmiques dels actes d'imaginació: el marc comú per als actes d'imaginació i el rombe de la imaginació. Partint d'aquesta nova teoria, definim la lògica dels actes d'imaginació, en què introduïm quatre algorismes diferents que comporten una representació molt més modular de la imaginació. Finalment, presentem la implementació del prototip d'un programa informàtic que captura els algorismes definits en la lògica anterior.

We study the dynamics of imagination acts at a philosophical, formal and applied level. Our research is based on three theories that identify the mechanisms involved in imagination acts and show how all of them share a similar structure. We define the Logic of Imaginary Scenarios, in which we create a layer for imagination acts upon a single-agent epistemic logic. While discussing the properties of logic, we note that the way in which imaginary worlds are developed is oversimplified. A deeper analysis leads to the definition of a new theory especially suited for the dynamics of imagination acts, called the Common Frame for Imagination Acts, and the Rhombus of Imagination. With this new theory at hand, we define the Logic of Imagination Acts, in which we introduce four different algorithms that allow for a much more modular account of imagination. Finally, we provide an implementation of a computer programme prototype that captures the algorithms defined by our latter logic.

Résumé :

The modeling of trees is challenging due to their complex branching structures. Three different ways to generate trees are using real world data for reconstruction, interactive modeling methods and modeling with procedural or rule-based systems. Procedural content generation is the idea of using algorithms to automate content creation processes, and it is useful in plant modeling since it can generate a wide variety of plants that can adapt and react to the environment and changing conditions. This thesis focuses on and extends a procedural tree generation technique that uses a space colonization algorithm to model the tree branches' competition for space, and shifts the previous works' focus from realism to fantasy. The technique satisfied the idea of using interaction between the tree's internal and external factors to determine its final shape, by letting the designer control the where and the how of the tree's growth process. The implementation resulted in a tree generation application where the user's imagination decides the limit of what can be produced, and if that limit is reached can the application be used to randomly generate a wide variety of trees and tree-like structures. A motivation for many researchers in the procedural content generation area is how it can be used to augment human imagination. The result of this thesis can be used for that, by stepping away from the restrictions of realism, and with ease let the user generate widely diverse trees, that are not necessarily realistic but, in most cases, adapts to the idea of a tree.

Résumé :

La deuxième moitié du XXè siècle a vu l'explosion de l'ordre des appareils et de leur milieu, la technologie. L'art n'est pas resté à l'abri de cette invasion, et les œuvres ont, elles aussi, commencé de s'appareiller. Ces œuvres appareillées sont dynamiques, indéterminées, interactives, algorithmiques, instables. Nous chercherons ici à suivre cette irruption technologique dans les différents régimes artistiques : au moment de la création de l'œuvre, dans son existence objectale et au moment de sa réception esthétique. Se dessinera alors, peut-être, une forme spécifique à ce que pourrait être un « art technologique ». L'analyse finie, les lignes de fracture posées – la question décisive pourra alors être posée, à défaut d'être tranchée : l'art survit-il à sa collusion avec la technologie ?
During the second half of the 20th century, the world of devices and their technological ground have tremendously spread. Art, also, has been impacted by this invasion, and some artworks have become equipped-artworks. Those specific artworks are : unstable, dynamic, algorithmic, unseen, interactive. We will try here to follow this technological invasion in the three different places of the artistic regime : how the artist creates his piece of work, how this object appears and exists, and how the spectator receives it. Thus, might appear a new form for a genuine « technological art »… Finally, we will be able to ask the core question and to tackle the main issue : are art and technology compatible ?

Résumé :

Sociala medier är ett fenomen som utvecklats drastiskt under de senaste 20 åren. Instagram och Facebook är två av de mest använda sociala medieplattformarna som har utvecklats markant med digitaliseringen. År 2016 ändrade Instagram sin algoritm, och 2018 gjorde Facebook samma sak. Algoritmerna syftar nu till att skräddarsy användarnas flöde för att visa det som är mest relevant till respektive konto och föra människor närmare varandra. Studien syftar till att undersöka hur Instagrams och Facebooks algoritmer fungerar och påverkar människor. Arbetet ska klargöra hur en algoritm uppfattas, hur plattformarna kan ha gått ifrån sina ursprungliga användningssyften och vilka etiska frågor som väckts till liv i processen. För att uppfylla studiens syfte skapas en undersökning utifrån tre generationer för att studera hur algoritmer påverkar människor och den roll som algoritmer spelar i samhället. Arbetet tar upp såväl positiva som negativa aspekter i relation till algoritmer. En kvalitativ undersökning med kvantifierbar data grundar strukturerade intervjuer i form av webbaserade frågeformulär. I ett första stadie ska respondenterna svara på ett frågeformulär. I nästa stadie ska respondenterna titta på dokumentärfilmen The Social Dilemma och sedan svara på efterföljande frågor i ett avslutande skede.

Texte intégral

Résumé :

Cette thèse examine l’imagination des systèmes de mesure de la performance au sein de l’industrie pharmaceutique. Par une observation participante étendue dans une grande entreprise pharmaceutique et des entretiens dans cette industrie, les trois articles de cette thèse explorent les influences intra et extra-organisationnelles qui agissent sur la forme et les raisons des systèmes de rémunération que les sociétés pharmaceutiques utilisent pour leur force de vente. Le premier article considère que les systèmes comptables émergent d’un ensemble d’inscriptions dramatisées qui mettent en scène, encadrent et médiatisent l’interaction entre les différents acteurs, internes et externes à l’organisation, qui participent à la fabrication d’un algorithme de rémunération. Le deuxième article théorise de quelle manière moral imaginaries sont constitués en objets comptables et comment les instruments comptables agissent comme médiateur moral. Il présente les systèmes émergents de mesure de la performance en tant que dispositifs de calcul moral façonnés par les imaginaires moraux contrastés de concepteurs hétérogènes. Le troisième article se concentre sur la manière dont les systèmes de mesure de la performance émergent et se stabilisent dans le contexte des marchés, afin d'explorer les infrastructures comptables au niveau de l’industrie que permettent aux acteurs organisationnels de visualiser, rendre compte et agir sur le marché lorsque ce dernier est invisible à pour ses participants. Pour que les systèmes de mesure de la performance fonctionnent sur un marché, il est nécessaire d’avoir une collaboration au sein du secteur, des opacités construites et des processus de (de)commercialisation de l’identité des acteurs
This thesis examines the field-level imagining of Performance Measurement Systems in the pharmaceutical sector. By means of an extended participant observation in a Big Pharma company and interviews in the pharmaceutical sector, the three articles of this thesis explore the intra- and extra-organizational influences that act upon the shape and rationales of the compensation systems pharmaceutical companies operate for their sales-force. The first article explores accounting systems as emerging from a set of dramatized inscriptions that stage, frame, and mediate interaction among the different actors, internal and external to the organization, that participate in the fabrication of a compensation algorithm. The second article theorizes in what way moral imaginaries are constituted into accounting objects, and how accounting acts as a moral mediator. It shows emergent performance measurement systems as moral calculating devices that are shaped by, and engage with, the contrasting moral imaginaries of heterogeneous designers. The third paper brings the concern with how performance measurement systems emerge and stabilize in the context of markets, to explore the field-level accounting infrastructures that enable organizational actors to visualize, account for, and act upon the market when the market is invisible to its participants. For performance measurement systems to work in a market, it is suggested, they require field-level collaboration, constructed opacities, and processes of marketization and de-marketization of actors’ identities

Résumé :

Given the centrality of algorithms in the media landscape, how do they affect people’s everyday lives? Drawing on 35 interviews with social media users about their encounters with algorithms online, the chapter considers the barely perceived transitions in power that occur when algorithms and people meet. When do people encounter algorithms, and what responses and imaginations do these encounters generate? Analyzing specific situations in which users notice algorithmic mechanisms at work and start reflecting and talking about them, the chapter shows how the algorithmic output of social media becomes culturally meaningful, as seen in the ways that people form opinions about specific systems and act strategically around them. The notion of the algorithmic imaginary is put forward to suggest that it might not always matter what the algorithm is but rather how and when people imagine and perceive algorithms as this is what shapes their orientations toward platforms.

Résumé :

This chapter turns to the scientific imaginary as it appears in the realm of art. It asserts that art has very often sought either to parody science or to diminish its claims to truth. Within this important post-Romantic strain of critique, this chapter isolates another voice that has sought to find a common imaginative ground between art and science. The chapter begins with Alfred Jarry's inauguration of the “science of 'Pataphysics” and ends with the literary refraction of Jarry's Gedankenexperimenten in the work of the Oulipo. The latter, in which the terms of art and criticism are uniquely joined, informs algorithmic criticism's emphasis on the liberating forces of (computationally enforced) constraint. Moreover, the chapter argues that this important modernist genealogy points to the primacy of pattern as the basic hermeneutical function that unites art, science, and criticism.

Résumé :

This article focuses on naturalism. It makes one terminological distinction: between methodological naturalism and ontological naturalism. The methodological naturalist assumes there is a fairly definite set of rules, maxims, or prescriptions at work in the “natural” sciences, such as physics, chemistry, and molecular biology, this constituting “scientific method.” There is no algorithm which tells one in all cases how to apply this method; nonetheless, there is a body of workers—the scientific community—who generally agree on whether the method is applied correctly or not. Whatever the method is, exactly—such virtues as simplicity, elegance, familiarity, scope, and fecundity appear in many accounts—it centrally involves an appeal to observation and experiment. Correct applications of the method have enormously increased our knowledge, understanding, and control of the world around us to an extent which would scarcely be imaginable to generations living prior to the age of modern science.

Résumé :

AbstractFundamental information on the collective motion of atoms can be learned by tracing imaginary phonon modes in deformed crystals. This should be useful to investigate the atomic process of plaston in a logical manner. Here, we summarize our works on the collective motion of atoms in unary metallic crystals examined by first principles phonon calculations. A simple algorithm for automated searching of the structural transition pathway following the imaginary phonon modes has been constructed. We first show the construction of structure evolution diagrams in Cu, Mg, Ti, and Hf by taking a simple cubic (SC) structure as a starting structure. The pathway corresponds to a route connecting initial and final structures without any energy barrier. Effects of the hydrostatic pressure on the diagram have been examined as well. In the second part, the collective motion of atoms in HCP-Ti under homogeneous shear deformation corresponding to the {$$10\overline{1} 2$$ 10 1 ¯ 2 } twinning mode is shown. The structural transition pathway from the parent to twin, which is widely accepted as the “shuffling”, is shown in detail.

Résumé :

As facial recognition is increasingly deployed around the world, from the US to China, civil liberties activists and democratic actors have drawn attention to its error rates and privacy invasions. The chapter unpacks new facets of algorithmic accountability, as it emerged nationally and transnationally by producing accounts of algorithmic error and by providing trustworthy explanations of what algorithms do. An algorithmic accountability and auditing industry has emerged to answer growing concerns that humans cannot trust fast-developing algorithms. Rather than analysing accountability through techniques of verification and responsibilization, we draw on scenes of contestation of facial recognition in China to develop another form of calling to account through refusal. Attending to refusal as a form of accountability expands the political scene of algorithmic interventions and challenges how liberal and authoritarian imaginaries to technological innovation are allocated following geopolitical lines.

Résumé :

This chapter determines the existence of human imagination and creativity through the concept of human culture and meme. It aims to rebut the two assumptions governing creative imagination in humans. The first assumption suggests that imagination evolved because humans are biologically adaptive. The second assumption claims that the existence of consciousness is the driving force behind creativity and imagination. In this chapter, it is argued that human creativity is the result of evolutionary processes based on memes rather than genes. This concept suggests that if hominid ancestors of humans are capable of imitation, a new set of replicators are set loose driving human minds to become better at copying, storing, and recombining memes. This coevolution of memes and their copying machinery led to the modern imaginative minds which evolved not because they are biologically adaptive but because they are advantageous for the memes. Hence the driving force behind human imagination is therefore not consciousness but aevolutionary algorithm which function is not biological but memetic.

Résumé :

The third chapter builds on central ideas from Simondon’s work, such as the distinction between invention and concretization and the delineation of technical elements, individuals, and ensembles, to conceptualize algorithmic techniques as the central carriers of technicity and technical knowledge in the domain of software. In dialogue with the cultural techniques tradition, it addresses them as methods or heuristics for creating operation and behavior in computing and discusses how they are invented and stabilized. Algorithmic techniques, in this perspective, are at the same time material blocks of technicity, units of knowledge, vocabularies for expression in the medium of function, and constitutive elements of developers’ technical imaginaries.

Résumé :

A novel simplified analytical three-spheres intersection algorithm is presented for use with forward pose kinematics solutions of a four-cable-suspended robot (the method is applicable to various other cable-suspended robots with equal pole heights and three cables intersecting in one point). It is required that the vertical center heights of all three spheres are equal (otherwise one can use the existing more-complicated algorithm). We derive this new algorithm and show that the multiple solutions, algorithmic singularity, and imaginary solutions do not cause any trouble in practical implementation. The algorithmic singularity of the original three-spheres intersection algorithm regarding equal Z heights is eliminated with the new algorithm. The new algorithm requires significantly less computation compared with the original algorithm. Examples are presented to demonstrate the new three-spheres intersection algorithm for a 4-cable robot.

Résumé :

A well-known property in Fourier transform theory is that causality in one domain implies real-part sufficiency in the other domain. This property is the basis for the fact that the real and imaginary parts of a signal are related via the Hilbert transform, if the spectrum of the signal is causal. In wave propagation problems involving circular symmetry, it is the circularly symmetric two-dimensional Fourier transform, or equivalently the Hankel transform, which is of central importance. Because of the circular symmetry in such problems, the condition of causality is not applicable. However, in our work we have shown that under some circumstances, it is possible to relate the real and imaginary parts of a propagating field described by a Hankel transform. In this paper, an approximate real-part sufficiency condition for the Hankel transform is developed and an algorithm for reconstructing the real (or imaginary) component from the imaginary (or real) component is applied to synthetic and experimental underwater acoustic fields.

Résumé :

Microstructure-sensitive design is performed using a newly developed Multiscale Complex Step Method. Algorithmic implementation of the complex-step method is based on conventional multiscale Taylor or FE2 direct model, with the difference being that the microstructural deformation gradient is modeled as a complex number with a small imaginary component. We introduce methods to calculate derivatives of microstructural fields with respect to loading parameters. The sensitivities are used to identify optimal microstructures with desired elastic and plastic properties.

Résumé :

The A n of Mie scattering coefficients can be calculated by backward recurrence through a continued fraction technique,1 but extra terms are needed to obtain a stabilized A n value; thus forward recurrence is still preferred if the terms are needed before it becomes unstabilized. Using both forward and backward recurrence to study A n , we are able to determine the term where the forward recurrence is still allowed. By relating it to the refractive index of the medium, we find in the nonabsorbing medium, the valid term is proportional to the product of the refractive index of the medium and its size parameter. As the imaginery refractive index increases the valid term decreases, but it reaches the minimum as the imaginary part equals the real part of the refractive index. Using the nonabsorbing medium as a reference, we determine the valid term as the imaginary refractive index is not zero. The relationship of the valid term vs the precision of the machine is under study. This research was done on a twelve-digit HP 9845.
