  2. Enumerative Induction and Semi-uniform Convergence to the Truth.Hanti Lin - 2017 - In Alexandru Baltag, Jeremy Seligman & Tomoyuki Yamada, Logic, Rationality, and Interaction. LORI 2017. Lecture Notes in Computer Science, vol 10455. Springer. pp. 362-376.
    I propose a new definition of identification in the limit, also called convergence to the truth, as a new success criterion that is meant to complement, but not replace, the classic definition due to Putnam (1963) and Gold (1967). The new definition is designed to explain how it is possible to have successful learning in a kind of scenario that the classic account ignores—the kind of scenario in which the entire infinite data stream to be presented incrementally to the (...)

    Proximal and uniform convergence on apartness spaces.Luminiţa Simona Vîţă - 2003 - Mathematical Logic Quarterly 49 (3):255.
    The main purpose of this paper is to investigate constructively the relationship between proximal convergence, uniform sequential convergence and uniform convergence for sequences of mappings between apartness spaces. It is also shown that if the second space satisfies the Efremovic axiom, then proximal convergence preserves strong continuity.

    Gibbs' paradox and non-uniform convergence.K. G. Denbigh & M. L. G. Redhead - 1989 - Synthese 81 (3):283 - 312.
    It is only when mixing two or more pure substances along a reversible path that the entropy of the mixing can be made physically manifest. It is not, in this case, a mere mathematical artifact. This mixing requires a process of successive stages. In any finite number of stages, the external manifestation of the entropy change, as a definite and measurable quantity of heat, isa fully continuous function of the relevant variables. It is only at an infinite and unattainable limit (...)

    The development of the concept of uniform convergence in Karl Weierstrass’s lectures and publications between 1861 and 1886.Klaus Viertel - 2021 - Archive for History of Exact Sciences 75 (4):455-490.
    The history of uniform convergence is typically focused on the contributions of Cauchy, Seidel, Stokes, and Björling. While the mathematical contributions of these individuals to the concept of uniform convergence have been much discussed, Weierstrass is considered to be the actual inventor of today’s concept. This view is often based on his well-known article from 1841. However, Weierstrass’s works on a rigorous foundation of analytic and elliptic functions date primarily from his lecture courses at the University (...)

    Metrization of the Uniform Space and Effective Convergence.Y. Tsujii, T. Mori & M. Yasugi - 2002 - Mathematical Logic Quarterly 48 (S1):123-130.
    The subject of the present article is the following fact. Consider an effective uniform space. A generally constructed metric from the uniformity has the property that a sequence from the space effectively converges with respect to the uniform topology if and only if it does with respect to the induced metric. This can be shown without assuming the computability of the metric.

    Convergence of observables on quantum logics.W. Tomé & S. Gudder - 1990 - Foundations of Physics 20 (4):417-434.
    We define two types of convergence for observables on a quantum logic which we call M-weak and uniform M-weak convergence. These convergence modes correspond to weak convergence of probability measures. They are motivated by the idea that two (in general unbounded) observables are “close” if bounded functions of them are “close.” We show that M-weak and uniform M-weak convergence generalize strong resolvent and norm resolvent convergence for self-adjoint operators on a Hilbert space.

  10. Uniform probability.William Dembski - manuscript
    This paper develops a general theory of uniform probability for compact metric spaces. Special cases of uniform probability include Lebesgue measure, the volume element on a Riemannian manifold, Haar measure, and various fractal measures (all suitably normalized). This paper first appeared fall of 1990 in the Journal of Theoretical Probability, vol. 3, no. 4, pp. 611—626. The key words by which this article was indexed were: ε-capacity, weak convergence, uniform probability, Hausdorff dimension, and capacity dimension.

    Mediation and Convergent Sociality: Toward a Theory of Social Dialogue.Алексей Платонович Давыдов - 2024 - Russian Journal of Philosophical Sciences 67 (2):135-159.
    The article investigates the mechanisms shaping a new quality of social development in contemporary Russia amidst growing societal challenges. Four key mechanisms are explored: mediation, social dialogue, polysubjectivity, and convergence. These are analyzed for their role in fostering novel forms of social integration and development. The mechanisms serve as tools for studying and shaping the current interplay between tradition and innovation, cultural stasis and social dynamics across various sociocultural contexts and transitional processes. The paper draws upon works presented at (...)

    A nonstandard density theorem for weak topologies on Banach and Bochner spaces.Laurent Vanderputten - 2003 - Mathematical Logic Quarterly 49 (3):277-283.
    We prove a nonstandard density result. It asserts that if a particular formula is true for functions in a set K of linear continuous functions between Banach spaces E and D, then it remains valid for functions that are limits, in the uniform convergence topology on a given class ℳ of subsets of E, of nets of vectors in K. We then apply this result to various class ℳ and setsK in the context of E-valued Bochner integrable functions (...)

    In [9] we introduced a new framework for asymptotic probabilities, in which a $\sigma-additive$ measure is defined on the sample space of all sequences $A = $ of finite models, where the universe of An is {1, 2, .., n}. In this framework we investigated the strong 0-1 law for sentences, which states that each sentence either holds in An eventually almost surely or fails in An eventually almost surely. In this paper we define the strong convergence law for (...)

  14. The Possibility of a Uniform Legal Language at the Interplay of Legal Discourse, Semiotics and Blockchain Networks.Pierangelo Blandino - 2024 - International Journal for the Semiotics of Law - Revue Internationale de Sémiotique Juridique 1 (7):2083-2111.
    This paper explores the possibility of a standard legal language (e.g. English) for a principled evolution of law in line with technological development. In doing so, reference is made to blockchain networks and smart contracts to emphasise the discontinuity with the liberal legal tradition when it comes to decentralisation and binary code language. Methodologically, the argument is built on the underlying relation between law, semiotics and new forms of media adding to natural language; namely: code and symbols. In what follows, (...)

    Pragmatism, Critical Theory and Business Ethics: Converging Lines.Max Visser - 2019 - Journal of Business Ethics 156 (1):45-57.
    There is a “Pragmatist turn” visible in the field of organization science today, resulting from a renewed interest in the work of Pragmatist philosophers like Dewey, Mead, Peirce, James and others, and in its implications for the study of organizations. Following Wicks and Freeman, in the past decade Pragmatism has also entered the field of business ethics, which, however, has not been uniformly applauded in that field. Some scholars fear that Pragmatism may enhance already existing positivist and managerialist tendencies in (...)

    The dominated convergence theorem implies that if is a sequence of functions on a probability space taking values in the interval [0, 1], and converges pointwise a.e., then converges to the integral of the pointwise limit. Tao [26] has proved a quantitative version of this theorem: given a uniform bound on the rates of metastable convergence in the hypothesis, there is a bound on the rate of metastable convergence in the conclusion that is independent of the (...)

    We examined social facilitation and emotional convergence in amusement, sadness, and fear in dynamic interactions. Dyads of friends or strangers jointly watched emotion-eliciting films while they either could or could not communicate nonverbally. We assessed three components of each emotion (expressions, appraisals, and feelings), as well as attention to and social motives toward the co-participant. In Study 1, participants interacted through a mute videoconference. In Study 2, they sat next to each other and either were or were not separated (...)

    Effective weak and vague convergence of measures on the real line.Diego A. Rojas - 2023 - Archive for Mathematical Logic 63 (1):225-238.
    We expand our effective framework for weak convergence of measures on the real line by showing that effective convergence in the Prokhorov metric is equivalent to effective weak convergence. In addition, we establish a framework for the study of the effective theory of vague convergence of measures. We introduce a uniform notion and a non-uniform notion of vague convergence, and we show that both these notions are equivalent. However, limits under effective vague (...) may not be computable even when they are finite. We give an example of a finite incomputable effective vague limit measure, and we provide a necessary and sufficient condition so that effective vague convergence produces a computable limit. Finally, we determine a sufficient condition for which effective weak and vague convergence of measures coincide. As a corollary, we obtain an effective version of the equivalence between classical weak and vague convergence of sequences of probability measures. (shrink)

    In this paper we develop a method for finding, under general conditions, explicit and highly uniform rates of convergence for the Picard iteration sequences for selfmaps on bounded metric spaces from ineffective proofs of convergence to a unique fixed point. We are able to extract full rates of convergence by extending the use of a logical metatheorem recently proved by Kohlenbach. In recent case studies we were able to find such explicit rates of convergence in (...)

    Classifying Dini's Theorem.Josef Berger & Peter Schuster - 2006 - Notre Dame Journal of Formal Logic 47 (2):253-262.
    Dini's theorem says that compactness of the domain, a metric space, ensures the uniform convergence of every simply convergent monotone sequence of real-valued continuous functions whose limit is continuous. By showing that Dini's theorem is equivalent to Brouwer's fan theorem for detachable bars, we provide Dini's theorem with a classification in the recently established constructive reverse mathematics propagated by Ishihara. As a complement, Dini's theorem is proved to be equivalent to the analogue of the fan theorem, weak König's (...)

    Vibration Suppression of a Coupled Aircraft Wing with Finite-Time Convergence.Yiming Liu, Zhifeng Tan, Xiaofen Yang & Xiaowei Wang - 2022 - Complexity 2022:1-14.
    A nonlinear coupled wing model subject to unknown external disturbances is proposed in this paper. Since the model is modeled by partial differential equations, the traditional control design scheme based on the ordinary differential equation model is not applicable, and the control law design becomes very complex. In this paper, a new antidisturbance boundary control scheme based on a finite time convergent disturbance observer is proposed. The control laws are designed based on the new disturbance observers to make the external (...)

  25. Should physicians be bayesian agents?M. Wayne Cooper - 1992 - Theoretical Medicine and Bioethics 13 (4).
    Because physicians use scientific inference for the generalizations of individual observations and the application of general knowledge to particular situations, the Bayesian probability solution to the problem of induction has been proposed and frequently utilized. Several problems with the Bayesian approach are introduced and discussed. These include: subjectivity, the favoring of a weak hypothesis, the problem of the false hypothesis, the old evidence/new theory problem and the observation that physicians are not currently Bayesians. To the complaint that the prior probability (...)

    Cauchy’s contribution to the foundations of analysis is often viewed through the lens of developments that occurred some decades later, namely the formalisation of analysis on the basis of the epsilon-delta doctrine in the context of an Archimedean continuum. What does one see if one refrains from viewing Cauchy as if he had read Weierstrass already? One sees, with Felix Klein, a parallel thread for the development of analysis, in the context of an infinitesimal-enriched continuum. One sees, with Emile Borel, (...)

  27. Why and how to construct an epistemic justification of machine learning?Petr Spelda & Vit Stritecky - 2024 - Synthese 204 (2):1-24.
    Consider a set of shuffled observations drawn from a fixed probability distribution over some instance domain. What enables learning of inductive generalizations which proceed from such a set of observations? The scenario is worthwhile because it epistemically characterizes most of machine learning. This kind of learning from observations is also inverse and ill-posed. What reduces the non-uniqueness of its result and, thus, its problematic epistemic justification, which stems from a one-to-many relation between the observations and many learnable generalizations? The paper (...)

    We give a new account of Björling’s contribution to uniform convergence in connection with Cauchy’s theorem on the continuity of an infinite series. Moreover, we give a complete translation from Swedish into English of Björling’s 1846 proof of the theorem. Our intention is also to discuss Björling’s convergence conditions in view of Grattan-Guinness’ distinction between history and heritage. In connection to Björling’s convergence theory we discuss the interpretation of Cauchy’s infinitesimals.

It follows that Z is exactly a difference of analytic sets when N is equipped with (...)

    Many prominent conceptions of moral progress implicitly assume that progress must lead to convergence in the moral domain. However, given the actual plurality of ways of life and attendant moral outlooks, there is no reason to assume improvement must lead to uniformity. Moreover, as the entanglement of the Enlightenment discourse of progress with colonialism makes evident, the assumption that progress must lead to convergence can license problematic practical conclusions. Drawing on insights from postcolonialist critique, I argue in favor (...)

    How Statistical Learning Can Play Well with Universal Grammar.Lisa S. Pearl - 2021 - In Nicholas Allott, Terje Lohndal & Georges Rey, A Companion to Chomsky. Wiley. pp. 267–286.
    A key motivation for Universal Grammar (UG) is developmental: UG can help children acquire the linguistic knowledge that they do as quickly as they do from the data that's available to them. Some of the most fruitful recent work in language acquisition has combined ideas about different hypothesis space building blocks with domain‐general statistical learning. Statistical learning can then provide a way to help navigate the hypothesis space in order to converge on the correct hypothesis. Reinforcement learning is a principled (...)

    Adaptive Neural Tracking Control for a Two-Joint Robotic Manipulator with Unknown Time-Varying Delays.Jiayao Wang & Yang Cui - 2022 - Complexity 2022:1-12.
    This paper presents an adaptive neural tracking control approach for a two-joint robotic manipulator with unknown time-varying delays. In order to work out the effect of unknown time-varying delays on the two-joint robotic manipulator, the appropriate Lyapunov–Krasovskii functionals and separation technology are chosen to settle this matter. The neural networks work as an approximator that has the advantage of estimating the unknown function in the system. In this paper, Lyapunov stability analysis can prove that all signals of the closed-loop system (...)

    Deletions of DNA in cancer and their possible uses for therapy.Alexander Varshavsky, Kim Lewis & Shun-Jia Chen - 2023 - Bioessays 45 (7):2300051.
    Despite advances in treatments over the last decades, a uniformly reliable and free of side effects therapy of human cancers remains to be achieved. During chromosome replication, a premature halt of two converging DNA replication forks would cause incomplete replication and a cytotoxic chromosome nondisjunction during mitosis. In contrast to normal cells, most cancer cells bear numerous DNA deletions. A homozygous deletion permanently marks a cell and its descendants. Here, we propose an approach to cancer therapy in which a pair (...)

    Variations in language abilities, use, and production style are ubiquitous within any given population. While research on language evolution has traditionally overlooked the potential importance of such individual differences, these can have an important impact on the trajectory of language evolution and ongoing change. To address this gap, we use a group communication game for studying this mechanism in the lab, in which micro-societies of interacting participants develop and use artificial languages to successfully communicate with each other.

    Incremental intervention effects in studies with dropout and many timepoints#.Ashley I. Naimi, Edward H. Kennedy & Kwangho Kim - 2021 - Journal of Causal Inference 9 (1):302-344.
    Modern longitudinal studies collect feature data at many timepoints, often of the same order of sample size. Such studies are typically affected by dropout and positivity violations. We tackle these problems by generalizing effects of recent incremental interventions to accommodate multiple outcomes and subject dropout. We give an identifying expression for incremental intervention effects when dropout is conditionally ignorable and derive the nonparametric efficiency bound for estimating such effects. Then we present efficient nonparametric estimators, showing that they converge at fast (...)

    The inverse of the distance between two structures $\mathscr{A} \not\equiv \mathscr{B}$ of finite type τ is naturally measured by the smallest integer q such that a sentence of quantifier rank q - 1 is satisfied by A but not by B. In this way the space $\operatorname{Str}^\tau$ of structures of type τ is equipped with a pseudometric. The induced topology coincides with the elementary topology of $\operatorname{Str}^\tau$ . Using the rudiments of the theory of uniform spaces, in this elementary (...)

    Pressure from the internationalization of economies and the globalization of nationally defined and managed welfare states could be a reason for converging trends in welfare states. On the other hand, it could be a reason for developing a more uniform type of welfare state, since a more uniform type, it could be assumed, would be under less pressure than a number of differing types. This may apply in particular in the case of welfare state models with high emphasis (...)

  44. Psychedelics, Meditation, and Self-Consciousness.Raphaël Millière, Robin L. Carhart-Harris, Leor Roseman, Fynn-Mathis Trautwein & Aviva Berkovich-Ohana - 2018 - Frontiers in Psychology 9:375105.
    In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been made (...)

  45. Is anything just plain good?Mahrad Almotahari & Adam Hosein - 2015 - Philosophical Studies 172 (6):1485-1508.
    Geach and Thomson have argued that nothing is just plain good, because ‘good’ is, logically, an attributive adjective. The upshot, according to Geach and Thomson, is that consequentialism is unacceptable, since its very formulation requires a predicative use of ‘good’. Reactions to the argument have, for the most part, been uniform. Authors have converged on two challenging objections . First, although the logical tests that Geach and Thomson invoke clearly illustrate that ‘good’, as commonly used, is an attributive, they (...)

    Non-World Indices and Assessment-Sensitivity.Peter Lasersohn - 2013 - Inquiry: An Interdisciplinary Journal of Philosophy 56 (2-3):122-148.
    I argue that sentence contents should be assigned truth-values relative to parameters other than a possible world only if those parameters are fixed by the context of assessment rather than the context of use. Standard counterexamples, including tense, de se attitudes, and knowledge ascriptions, all admit of alternative analyses which do not make use of such parameters. Moreover, allowing such indices greatly complicates the task of defining disagreement, and forces an odd separation between what is true, and what someone has (...)

    Unfinished Lives and Multiple Deaths: Bodies, Buddhists and Organ Donation.Tanya Maria Zivkovic - 2022 - Body and Society 28 (3):63-88.
    This article examines an Australian campaign to increase organ and tissue donation for transplantation. It analyses the use of the gift rhetoric to promote community awareness and resources, target migrant groups, and recruit cultural and religious leaders to endorse organ and tissue donation as an altruistic act. In unpacking this ‘gift of life’ approach to organ donation, it explores the convergence of medical and religious bodies and pushes beyond uniform determinations of death to reveal how multiple deaths transpire (...)

    A Q-Learning-Based Parameters Adaptive Algorithm for Formation Tracking Control of Multi-Mobile Robot Systems.Chen Zhang, Wen Qin, Ming-Can Fan, Ting Wang & Mou-Quan Shen - 2022 - Complexity 2022:1-19.
    This paper proposes an adaptive formation tracking control algorithm optimized by Q-learning scheme for multiple mobile robots. In order to handle the model uncertainties and external disturbances, a desired linear extended state observer is designed to develop an adaptive formation tracking control strategy. Then an adaptive method of sliding mode control parameters optimized by Q-learning scheme is employed, which can avoid the complex parameter tuning process. Furthermore, the stability of the closed-loop control system is rigorously proved by means of matrix (...)

    A sheaf-theoretic foundation for nonstandard analysis.Erik Palmgren - 1997 - Annals of Pure and Applied Logic 85 (1):69-86.
    A new foundation for constructive nonstandard analysis is presented. It is based on an extension of a sheaf-theoretic model of nonstandard arithmetic due to I. Moerdijk. The model consists of representable sheaves over a site of filter bases. Nonstandard characterisations of various notions from analysis are obtained: modes of convergence, uniform continuity and differentiability, and some topological notions. We also obtain some additional results about the model. As in the classical case, the order type of the nonstandard natural (...)

    Dynamic Learning from Adaptive Neural Control of Uncertain Robots with Guaranteed Full-State Tracking Precision.Min Wang, Yanwen Zhang & Huiping Ye - 2017 - Complexity 2017:1-14.
    A dynamic learning method is developed for an uncertain n-link robot with unknown system dynamics, achieving predefined performance attributes on the link angular position and velocity tracking errors. For a known nonsingular initial robotic condition, performance functions and unconstrained transformation errors are employed to prevent the violation of the full-state tracking error constraints. By combining two independent Lyapunov functions and radial basis function neural network approximator, a novel and simple adaptive neural control scheme is proposed for the dynamics of the (...)
