    Writing Facts: Interdisciplinary Discussions of a Key Concept in Modernity

    Get PDF
    "Fact" is one of the most crucial inventions of modern times. Susanne Knaller discusses the functions of this powerful notion in the arts and the sciences, its impact on aesthetic models and systems of knowledge. The practice of writing provides an effective procedure to realize and to understand facts. This concerns preparatory procedures, formal choices, models of argumentation, and narrative patterns. By considering "writing facts" and "writing facts", the volume shows why and how "facts" are a result of knowledge, rules, and norms as well as of description, argumentation, and narration. This approach allows new perspectives on »fact« and its impact on modernity

    OCDaf: Ordered Causal Discovery with Autoregressive Flows

    Full text link
    We propose OCDaf, a novel order-based method for learning causal graphs from observational data. We establish the identifiability of causal graphs within multivariate heteroscedastic noise models, a generalization of additive noise models that allow for non-constant noise variances. Drawing upon the structural similarities between these models and affine autoregressive normalizing flows, we introduce a continuous search algorithm to find causal structures. Our experiments demonstrate state-of-the-art performance across the Sachs and SynTReN benchmarks in Structural Hamming Distance (SHD) and Structural Intervention Distance (SID). Furthermore, we validate our identifiability theory across various parametric and nonparametric synthetic datasets and showcase superior performance compared to existing baselines

    The Politics of Platformization: Amsterdam Dialogues on Platform Theory

    Get PDF
    What is platformization and why is it a relevant category in the contemporary political landscape? How is it related to cybernetics and the history of computation? This book tries to answer such questions by engaging in multidisciplinary dialogues about the first ten years of the emerging fields of platform studies and platform theory. It deploys a narrative and playful approach that makes use of anecdotes, personal histories, etymologies, and futurable speculations to investigate both the fragmented genealogy that led to platformization and the organizational and economic trends that guide nowadays platform sociotechnical imaginaries

    Vitalism and Its Legacy in Twentieth Century Life Sciences and Philosophy

    Get PDF
    This Open Access book combines philosophical and historical analysis of various forms of alternatives to mechanism and mechanistic explanation, focusing on the 19th century to the present. It addresses vitalism, organicism and responses to materialism and its relevance to current biological science. In doing so, it promotes dialogue and discussion about the historical and philosophical importance of vitalism and other non-mechanistic conceptions of life. It points towards the integration of genomic science into the broader history of biology. It details a broad engagement with a variety of nineteenth, twentieth and twenty-first century vitalisms and conceptions of life. In addition, it discusses important threads in the history of concepts in the United States and Europe, including charting new reception histories in eastern and south-eastern Europe. While vitalism, organicism and similar epistemologies are often the concern of specialists in the history and philosophy of biology and of historians of ideas, the range of the contributions as well as the geographical and temporal scope of the volume allows for it to appeal to the historian of science and the historian of biology generally

    Multisensory processing, affect and multimodal manipulation: A cognitive-semiotic empirical study of travel documentaries

    Get PDF
    Multisensory processing represents the mirror image of multimodal meaning-making, in that interpreting multimodal discourse predominantly requires multisensory processing, even when different modes rely on the same sensory channels (Khateb et al., 2002), for example images and text in a book (Gibbons, 2012, p. 40). Remley (2017) makes a similar point when discussing the neuroscience of multimodal persuasive messages, when he asserts that “[t]he term ‘multisensory integration’ is the biological equivalent of the term ‘multimodal’ in rhetoric” (p. 9). An understanding of multisensory processing can therefore be (and presumably is) exploited at the stage of text-production as a resource for manipulative multimodal discourses, with all the ideological consequences that entails. The concept of manipulation has been a matter of discussion in critical discourse studies (CDS) and pragmatics for more than a decade. Agreement on how to define and analyse the latter has yet to be reached, although most scholars seem to agree that Relevance Theory (Sperber and Wilson, 1995) can provide a useful entry point thanks to its theorisation of variable contexts and individual cognitive environments (de Saussure, 2005; Maillat, 2013; Maillat and Oswald, 2009; Oswald, 2014). Moreover, the concept of epistemic vigilance (Sperber et al., 2010) has been used to investigate the cognitive barriers that need to be bypassed in order for manipulation to work (Hart, 2013; Mazzarella, 2015). Finally, Sorlin (2017: 133) recently highlighted the need to focus not only on the cognitive aspects influencing manipulation, but also on “the psychological aspect of manipulation that often consists in exploiting the target's weaknesses”, thus pointing towards the dimension of affect as a further explanatory force. This paper begins with an overview of the concepts of manipulation and epistemic vigilance, before discussing insights from the field of multisensory processing in the neurosciences. Then, drawing on some principles from Relevance Theory (Sperber and Wilson, 1995) and looking at some data from travel documentary programmes and their viewers, examples are offered of how manipulation is attempted and achieved through this specific multimodal genre in individual case studies. The focus of the analysis will be on bottom-up (i.e. text-driven) processes and the interpretation/reaction of an audience. The research draws on a novel methodological approach (Castaldi, 2021) that integrates Audience Research (e.g., Schrþder et al., 2003) and Social Semiotics (e.g. Kress and van Leeuwen, 1996, 2001; van Leeuwen, 1999; Machin and Mayr, 2012) in order to analyse media interactions in their individuality. Results suggest that the affective dimension, predominantly attended to through sonic and visual modes, plays a key role for multimodal manipulation to successfully occur

    Intelligent computing : the latest advances, challenges and future

    Get PDF
    Computing is a critical driving force in the development of human civilization. In recent years, we have witnessed the emergence of intelligent computing, a new computing paradigm that is reshaping traditional computing and promoting digital revolution in the era of big data, artificial intelligence and internet-of-things with new computing theories, architectures, methods, systems, and applications. Intelligent computing has greatly broadened the scope of computing, extending it from traditional computing on data to increasingly diverse computing paradigms such as perceptual intelligence, cognitive intelligence, autonomous intelligence, and human computer fusion intelligence. Intelligence and computing have undergone paths of different evolution and development for a long time but have become increasingly intertwined in recent years: intelligent computing is not only intelligence-oriented but also intelligence-driven. Such cross-fertilization has prompted the emergence and rapid advancement of intelligent computing

    Affinity-Based Reinforcement Learning : A New Paradigm for Agent Interpretability

    Get PDF
    The steady increase in complexity of reinforcement learning (RL) algorithms is accompanied by a corresponding increase in opacity that obfuscates insights into their devised strategies. Methods in explainable artificial intelligence seek to mitigate this opacity by either creating transparent algorithms or extracting explanations post hoc. A third category exists that allows the developer to affect what agents learn: constrained RL has been used in safety-critical applications and prohibits agents from visiting certain states; preference-based RL agents have been used in robotics applications and learn state-action preferences instead of traditional reward functions. We propose a new affinity-based RL paradigm in which agents learn strategies that are partially decoupled from reward functions. Unlike entropy regularisation, we regularise the objective function with a distinct action distribution that represents a desired behaviour; we encourage the agent to act according to a prior while learning to maximise rewards. The result is an inherently interpretable agent that solves problems with an intrinsic affinity for certain actions. We demonstrate the utility of our method in a financial application: we learn continuous time-variant compositions of prototypical policies, each interpretable by its action affinities, that are globally interpretable according to customers’ financial personalities. Our method combines advantages from both constrained RL and preferencebased RL: it retains the reward function but generalises the policy to match a defined behaviour, thus avoiding problems such as reward shaping and hacking. Unlike Boolean task composition, our method is a fuzzy superposition of different prototypical strategies to arrive at a more complex, yet interpretable, strategy.publishedVersio

    An onto-epistemological (re)framing and (re)connecting of organisations as praxeological multi-capital value systems

    Get PDF
    Organisation stands as one of humankind’s greatest inventions, and reconceptualising organisations to meet the ever-diversifying needs of the modern stakeholder community one of its most significant challenges. Historically, scientific management principles simplified the challenge through a profitable operations practice imperative, which reinforced a creation and destruction value dualism, and causal and value dead ends. However, value is contingent upon meeting needs, demanding that organisations leverage a wider and connected set of capitals to meet the diverse needs of modernity. This research seeks to understand how praxeologically inert legacy organisations can generate value by (re)connecting capitals and (re)framing as multi-capital value systems. The study’s setting is the university-led Made Smarter Leadership Development programme which provided an insightful longitudinal case study over the two-year programme life-cycle. The research surfaced rich qualitative insights on participant sense-making journeys across a diverse set of participant-researcher touchpoints, and also collected associated quantitative survey data. Analysis was conducted in three streams, and iteratively built up a complementary organisational model ontology. Stream one, a qualitative ethnographic study utilised grounded theory analysis to surface the prñxis (re)framing priorities of organisations. Analysis of such priorities yielded an onto-epistemological perspective of an organisation, and novel insights were generated on prñxis (re)framing strategies, organisational maturity, and how prñxes and frames combine as a relational onto-epistemological duality. Stream two’s quantitative analysis of respondent data identified the 20 significant prñxis-elements that form six systemically correlated and causally related capital factors. Findings indicate how multiple capitals connect as an organisational structure which orchestrates value flows between capital factors. Stream three elaborated on the prior two streams’ empirically-grounded foundations through sensemaking systems dynamics theory. This modelling produced both empirical findings and a generalisable methodology to reconceptualise organisations as a connected praxeological multi-capital value system. Specifically, findings informed how means-ends dynamics orchestrate complex capital interactions, which form pan-organisational value journeys, and ultimately form generalisable value archetypes. In summary, the research confirmed an organisation is a connected multi-capital praxeological value system, this outcome enabled by the discovery of a novel onto-epistemological perspective of organisations
