  1. Approximate Counting by Hashing in Bounded Arithmetic.Emil Jeřábek - 2009 - Journal of Symbolic Logic 74 (3):829-860.
    We show how to formalize approximate counting via hash functions in subsystems of bounded arithmetic, using variants of the weak pigeonhole principle. We discuss several applications, including a proof of the tournament principle, and an improvement on the known relationship of the collapse of the bounded arithmetic hierarchy to the collapse of the polynomial-time hierarchy.

  2. Reply to Rosanna Keefe’s ‘Modelling Higher-Order Vagueness: Columns, Borderlines and Boundaries’.Susanne Bobzien - 2016
    This paper is an expanded written version of my reply to Rosanna Keefe’s paper ‘Modelling higher-order vagueness: columns, borderlines and boundaries’ (Keefe 2015), which in turn is a reply to my paper ‘Columnar higher-order vagueness, or Vagueness is higher-order vagueness’ (Bobzien 2015). Both papers were presented at the Joint Session of the the Aristotelian Society and the Mind Association in July, 2015. At the Joint Session meeting, there was insufficient time to present all of my points in response to (...)

  3. Review of Rosanna Keefe, Theories of Vagueness. [REVIEW]Brian Weatherson - 2003 - Philosophy and Phenomenological Research 67 (2):491-494.
    Many philosophers, I suspect, are partial to supervaluational theories of vagueness. And with good reason. Its rivals all seem to promise metaphysical mysteries concerning hitherto unnoticed, and perhaps unnoticeable, sharp boundaries around our concepts, or radical revision in our logical practices. And not only have philosophers been so tempted. The texts are a little unclear, but it seems several economists can be read as adopting supervaluational solutions to the difficulties raised by vagueness in economic concepts. Given its popularity, and plausibility, (...)

  11. Theories of Vagueness.Rosanna Keefe - 2000 - Cambridge University Press.
    Most expressions in natural language are vague. But what is the best semantic treatment of terms like 'heap', 'red' and 'child'? And what is the logic of arguments involving this kind of vague expression? These questions are receiving increasing philosophical attention, and in this book, first published in 2000, Rosanna Keefe explores the questions of what we should want from an account of vagueness and how we should assess rival theories. Her discussion ranges widely and comprehensively over the main (...)

  12. Discovering Binary Codes for Documents by Learning Deep Generative Models.Geoffrey Hinton & Ruslan Salakhutdinov - 2011 - Topics in Cognitive Science 3 (1):74-91.
    We describe a deep generative model in which the lowest layer represents the word-count vector of a document and the top layer represents a learned binary code for that document. The top two layers of the generative model form an undirected associative memory and the remaining layers form a belief net with directed, top-down connections. We present efficient learning and inference procedures for this type of generative model and show that it allows more accurate and much faster retrieval than latent (...)

    A method for sharing private data through personalized searches is described. This method enables users to retrieve access-controlled private data as well as publicly available data by submitting a single query to a conventional search engine. Seamless integration of the method into current search services through a prototype on the Mozilla Firefox web browser, without any changes to existing search functions, such as crawling, indexing, and matching, is also described. Evaluations showed that the additional storage requirement is only 10% and (...)

    Vagueness: A Reader.Rosanna Keefe & Peter Smith (eds.) - 1996 - MIT Press.
    Vagueness is currently the subject of vigorous debate in the philosophy of logic and language. Vague terms -- such as 'tall', 'red', 'bald', and 'tadpole' -- have borderline cases ; and they lack well-defined extensions. The phenomenon of vagueness poses a fundamental challenge to classical logic and semantics, which assumes that propositions are either true or false and that extensions are determinate.This anthology collects for the first time the most important papers in the field. After a substantial introduction that surveys (...)
  17. What Logical Pluralism Cannot Be.Rosanna Keefe - 2014 - Synthese 191 (7):1375-1390.
    Logical Pluralists maintain that there is more than one genuine/true logical consequence relation. This paper seeks to understand what the position could amount to and some of the challenges faced by its formulation and defence. I consider in detail Beall and Restall’s Logical Pluralism—which seeks to accommodate radically different logics by stressing the way that they each fit a general form, the Generalised Tarski Thesis (GTT)—arguing against the claim that different instances of GTT are admissible precisifications of logical consequence. I (...)

  18. Vagueness Without Context Change.Rosanna Keefe - 2007 - Mind 116 (462):275-292.
    In this paper I offer a critique of the recent popular strategy of giving a contextualist account of vagueness. Such accounts maintain that truth-values of vague sentences can change with changes of context induced by confronting different entities (e.g. different pairs through a sorites series). I claim that appealing to context does not help in solving the sorites paradox, nor does it give us new insights into vagueness per se. Furthermore, the contextual variation to which the contextualist is committed is (...)

    What the world needs now is another theory of vagueness. Not because the old theories are useless. Quite the contrary, the old theories provide many of the materials we need to construct the truest theory of vagueness ever seen. The theory shall be similar in motivation to supervaluationism, but more akin to many-valued theories in conceptualisation. What I take from the many-valued theories is the idea that some sentences can be truer than others. But I say very different things to (...)

    Are Artworks More Like People Than Artifacts? Individual Concepts and Their Extensions.George E. Newman, Daniel M. Bartels & Rosanna K. Smith - 2014 - Topics in Cognitive Science 6 (4):647-662.
    This paper examines people's reasoning about identity continuity and its relation to previous research on how people value one-of-a-kind artifacts, such as artwork. We propose that judgments about the continuity of artworks are related to judgments about the continuity of individual persons because art objects are seen as physical extensions of their creators. We report a reanalysis of previous data and the results of two new empirical studies that test this hypothesis. The first study demonstrates that the mere categorization of (...)

  23. Phenomenal Sorites Paradoxes and Looking the Same.Rosanna Keefe - 2011 - Dialectica 65 (3):327-344.
    Taking a series of colour patches, starting with one that clearly looks red, and making each so similar in colour to the previous one that it looks the same as it, we appear to be able to show that a yellow patch looks red. I ask whether phenomenal sorites paradoxes, such as this, are subject to a unique kind of solution that is unavailable in relation to other sorites paradoxes. I argue that they do not need such a solution, nor (...)

    II—Modelling Higher-Order Vagueness: Columns, Borderlines and Boundaries.Rosanna Keefe - 2015 - Aristotelian Society Supplementary Volume 89 (1):89-108.
    According to columnar higher-order vagueness, all orders of vagueness coincide: any borderline case is a borderline borderline case, and a third-order borderline case, etc. Bobzien has worked out many details of such a theory and models it with a modal logic closely related to S4. I take up a range of questions about the framework and argue that it is not suitable for modelling the structure of vagueness and higher-order vagueness.

    In 1966, a team made up of Brazilian and foreign scientists spent a week carefully recording the body temperature and other clinical signs and symptoms of 110 Tiriyó Indigenous people in their communities along the Brazil-Suriname border. Led by the Yale University virologist and immunologist Francis Black, the researchers faced an "epidemic" with a special profile, distinct from those most common in Indigenous populations, which usually resulted in widespread illness, the collapse of subsistence activities, hunger, and as a rule, elevated (...)

  29. Contingent Identity and Vague Identity.Rosanna Keefe - 1995 - Analysis 55 (3):183 - 190.
    Evan's influential argument against vague objects (_Analysis<D>, 1978) has a parallel directed against contingent identity. I argue that Noonan failed in his attempt to accept Evans's argument but save contingent identity by establishing a disanalogy between the two arguments (in The Philosophical Quarterly 1991). Instead, I suggest an alternative way to block the argument against contingent identity and argue that its analogue provides a satisfactory response to Evans's original argument.

    When Does Circularity Matter?Rosanna Keefe - 2002 - Proceedings of the Aristotelian Society 102 (3):253–270.
    This paper asks whether a good philosophical account of something can ever be circular. It explores the kind of circumstances in which an account of F might involve F itself while still serving the functions of and meeting the requirements on a philosophical account. The paper discusses two criteria for acceptable circularity, based on ideas from Humberstone 1997. And it illustrates the surprisingly wide variety of kinds of accounts in which circularity need not be bad.

    Kinds of Authenticity.George E. Newman & Rosanna K. Smith - 2016 - Philosophy Compass 11 (10):609-618.
    The concept of authenticity plays an important role in how people reason about objects, other people, and themselves. However, despite a great deal of academic interest in this concept, to date, the precise meaning of the term, authenticity, has remained somewhat elusive. This paper reviews the various definitions of authenticity that have been proposed in the literature and identifies areas of convergence. We then outline a novel framework that organizes the existing definitions of authenticity along two key dimensions: describing the (...)

  32. Modelling Vagueness: What Can We Ignore?Rosanna Keefe - 2012 - Philosophical Studies 161 (3):453-470.
    A theory of vagueness gives a model of vague language and of reasoning within the language. Among the models that have been offered are Degree Theorists’ numerical models that assign values between 0 and 1 to sentences, rather than simply modelling sentences as true or false. In this paper, I ask whether we can benefit from employing a rich, well-understood numerical framework, while ignoring those aspects of it that impute a level of mathematical precision that is not present in the (...)

    Vagueness by Numbers.Rosanna Keefe - 1998 - Mind 107 (427):565-579.
    Degree theories of vagueness build on the observation that vague predicates such as 'tall' and 'red' come in degrees. They employ an infinite-valued logic, where the truth values correspond to degrees of truth and are typically represented by the real numbers in the interval [0,1]. In this paper, the success with which the numerical assignments of such theories can capture the phenomenon of vagueness is assessed by drawing an analogy with the measurement of various physical quantities using real numbers. I (...)

  37. Trivalent Semantics and the Vaguely Vague.Steven Gross - 2007 - Synthese 156 (1):97-117.
    Michael Tye responds to the problem of higher-order vagueness for his trivalent semantics by maintaining that truth-value predicates are “vaguely vague”: it’s indeterminate, on his view, whether they have borderline cases and therefore indeterminate whether every sentence is true, false, or indefinite. Rosanna Keefe objects (1) that Tye’s argument for this claim tacitly assumes that every sentence is true, false, or indefinite, and (2) that the conclusion is any case not viable. I argue – contra (1) – that Tye’s (...)

    Vagueness. By Timothy Williamson. [REVIEW]Rosanna Keefe - 1995 - Philosophical Quarterly 45 (180):392-394.
    If you keep removing single grains of sand from a heap, when is it no longer a heap? From discussions of the heap paradox in classical Greece, to modern formal approaches like fuzzy logic, Timothy Williamson traces the history of the problem of vagueness. He argues that standard logic and formal semantics apply even to vague languages and defends the controversial, realist view that vagueness is a form of ignorance - there really is a grain of sand whose removal turns (...)

    A number of recent accounts for vague terms postulate a kind of context-sensitivity, one that kicks in after the usual ‘external’ contextual factors like comparison class are established and held fixed. In a recent paper, ‘Vagueness without Context Change’: 275–92), Rosanna Keefe criticizes all such accounts. The arguments are variations on considerations that have been brought against context-sensitive accounts of knowledge, predicates of personal taste, epistemic modals, and the like. The issues are well known and there are variety of (...)

    It is argued that “human-centredness” will be an important characteristic of systems that learn tasks from human users, as the difficulties in inductive inference rule out learning without human assistance. The aim of “programming by example” is to create systems that learn how to perform tasks from their human users by being shown examples of what is to be done. Just as the user creates a learning environment for the system, so the system provides a teaching opportunity for the user, (...)

    Degrees of Belief, Expected and Actual.Rosanna Keefe - 2017 - Synthese 194 (10):3789-3800.
    A framework of degrees of belief, or credences, is often advocated to model our uncertainty about how things are or will turn out. It has also been employed in relation to the kind of uncertainty or indefiniteness that arises due to vagueness, such as when we consider “a is F” in a case where a is borderline F. How should we understand degrees of belief when we take into account both these phenomena? Can the right kind of theory of the (...)
