The objective of this work is to propose ten efficient scaling techniques for the Wisconsin Diagnosis Breast Cancer dataset using the support vector machine. These scaling techniques are efficient for the linear programming approach. SVM with proposed scaling techniques was applied on the WDBC dataset. The scaling techniques are, namely, arithmetic mean, de Buchet for three cases p = 1,2, and ∞, equilibration, geometric mean, IBM MPSX, and Lp-norm for three cases p = 1,2, and ∞. The experimental results show (...) that the equilibration scaling technique overcomes the benchmark normalization scaling technique used in many commercial solvers. Finally, the experimental results also show the effectiveness of the grid search technique which gets the optimal parameters for the SVM classifier. (shrink)

Most philosophers agree that causal knowledge is essential to decision-making: agents should choose from the available options those that probably cause the outcomes that they want. This book argues against this theory and in favour of evidential or Bayesian decision theory, which emphasises the symptomatic value of options over their causal role. It examines a variety of settings, including economic theory, quantum mechanics and philosophical thought-experiments, where causal knowledge seems to make a practical difference. The arguments make novel use of (...) machinery from other areas of philosophical inquiry, including first-person epistemology and the free will debate. The book also illustrates the applicability of decision theory itself to questions about the direction of time and the special epistemic status of agents. (shrink)

Combining physics, mathematics and computer science, quantum computing and its sister discipline of quantum information have developed in the past few decades from visionary ideas to two of the most fascinating areas of quantum theory. General interest and excitement in quantum computing was initially triggered by Peter Shor (1994) who showed how a quantum algorithm could exponentially “speed-up” classical computation and factor large numbers into primes far more efficiently than any (known) classical algorithm. Shor’s algorithm was soon followed by several (...) other algorithms that aimed to solve combinatorial and algebraic problems, and in the years since theoretical study of quantum systems serving as computational devices has achieved tremendous progress. Common belief has it that the implementation of Shor’s algorithm on a large scale quantum computer would have devastating consequences for current cryptography protocols which rely on the premise that all known classical worst-case algorithms for factoring take time exponential in the length of their input (see, e.g., Preskill 2005). Consequently, experimentalists around the world are engaged in attempts to tackle the technological difficulties that prevent the realisation of a large scale quantum computer. But regardless whether these technological problems can be overcome (Unruh 1995; Ekert and Jozsa 1996; Haroche and Raimond 1996), it is noteworthy that no proof exists yet for the general superiority of quantum computers over their classical counterparts. -/- The philosophical interest in quantum computing is manifold. From a social-historical perspective, quantum computing is a domain where experimentalists find themselves ahead of their fellow theorists. Indeed, quantum mysteries such as entanglement and nonlocality were historically considered a philosophical quibble, until physicists discovered that these mysteries might be harnessed to devise new efficient algorithms. But while the technology for harnessing the power of 50–100 qubits (the basic unit of information in the quantum computer) is now within reach (Preskill 2018), only a handful of quantum algorithms exist, and the question of whether these can truly outperform any conceivable classical alternative is still open. From a more philosophical perspective, advances in quantum computing may yield foundational benefits. For example, it may turn out that the technological capabilities that allow us to isolate quantum systems by shielding them from the effects of decoherence for a period of time long enough to manipulate them will also allow us to make progress in some fundamental problems in the foundations of quantum theory itself. Indeed, the development and the implementation of efficient quantum algorithms may help us understand better the border between classical and quantum physics (Cuffaro 2017, 2018a; cf. Pitowsky 1994, 100), and perhaps even illuminate fundamental concepts such as measurement and causality. Finally, the idea that abstract mathematical concepts such as computability and complexity may not only be translated into physics, but also re-written by physics bears directly on the autonomous character of computer science and the status of its theoretical entities—the so-called “computational kinds”. As such it is also relevant to the long-standing philosophical debate on the relationship between mathematics and the physical world. (shrink)

In What's the Use? Sara Ahmed continues the work she began in The Promise of Happiness and Willful Subjects by taking up a single word--in this case, use--and following it around. She shows how use became associated with life and strength in nineteenth century biological and social thought and considers how utilitarianism offered a set of educational techniques for shaping individuals by directing them toward useful ends. Ahmed also explores how spaces become restricted to some uses and users (...) with specific reference to universities. She notes, however, the potential for queer use: how things can be used in ways that were not intended or by those for whom they were not intended. Ahmed posits queer use as way of reanimating the project of diversity work as the ordinary and painstaking work of opening up institutions to those who have historically been excluded from them.

_The Promise of Happiness_ is a provocative cultural critique of the imperative to be happy. It asks what follows when we make our desires and even our own happiness conditional on the happiness of others: “I just want you to be happy”; “I’m happy if you’re happy.” Combining philosophy and feminist cultural studies, Sara Ahmed reveals the affective and moral work performed by the “happiness duty,” the expectation that we will be made happy by taking part in that which (...) is deemed good, and that by being happy ourselves, we will make others happy. Ahmed maintains that happiness is a promise that directs us toward certain life choices and away from others. Happiness is promised to those willing to live their lives in the right way. Ahmed draws on the intellectual history of happiness, from classical accounts of ethics as the good life, through seventeenth-century writings on affect and the passions, eighteenth-century debates on virtue and education, and nineteenth-century utilitarianism. She engages with feminist, antiracist, and queer critics who have shown how happiness is used to justify social oppression, and how challenging oppression causes unhappiness. Reading novels and films including_ Mrs. Dalloway_, _The Well of Loneliness_, _Bend It Like Beckham_, and _Children of Men_, Ahmed considers the plight of the figures who challenge and are challenged by the attribution of happiness to particular objects or social ideals: the feminist killjoy, the unhappy queer, the angry black woman, and the melancholic migrant. Through her readings she raises critical questions about the moral order imposed by the injunction to be happy. (shrink)

Differences That Matter challenges existing ways of theorising the relationship between feminism and postmodernism which ask 'is or should feminism be modern or postmodern?' Sara Ahmed suggests that postmodernism has been allowed to dictate feminist debates and calls instead for feminist theorists to speak (back) to postmodernism, rather than simply speak on (their relationship to) it. Such a 'speaking back' involves a refusal to position postmodernism as a generalisable condition of the world and requires closer readings of what postmodernism (...) is actually 'doing' in a variety of disciplinary contexts. Sara Ahmed hence examines constructions of postmodernism in relation to rights, ethics, subjectivity, authorship, meta-fiction and film. (shrink)

In _Willful Subjects_ Sara Ahmed explores willfulness as a charge often made by some against others. One history of will is a history of attempts to eliminate willfulness from the will. Delving into philosophical and literary texts, Ahmed examines the relation between will and willfulness, ill will and good will, and the particular will and general will. Her reflections shed light on how will is embedded in a political and cultural landscape, how it is embodied, and how will (...) and willfulness are socially mediated. Attentive to the wayward, the wandering, and the deviant, Ahmed considers how willfulness is taken up by those who have received its charge. Grounded in feminist, queer, and antiracist politics, her sui generis analysis of the willful subject, the figure who wills wrongly or wills too much, suggests that willfulness might be required to recover from the attempt at its elimination.

In the chapter “The Geometry of Visibles” in his ‘Inquiry into the Human Mind’, Thomas Reid constructs a special space, develops a special geometry for that space, and offers a natural model for this geometry. In doing so, Reid “discovers” non-Euclidean Geometry sixty years before the mathematicians. This paper examines this “discovery” and the philosophical motivations underlying it. By reviewing Reid’s ideas on visible space and confronting him with Kant and Berkeley, I hope, moreover, to resolve an alleged impasse in (...) Reid’s philosophy concerning the contradictory characteristics of Reid’s tangible and visible space. (shrink)

Recent suggestions to supply quantum mechanics (QM) with realistic foundations by reformulating it in light of quantum information theory (QIT) are examined and are found wanting by pointing to a basic conceptual problem that QIT itself ignores, namely, the measurement problem. Since one cannot ignore the measurement problem and at the same time pretend to be a realist, as they stand, the suggestions to reformulate QM in light of QIT are nothing but instrumentalism in disguise.

The purpose of this paper is to analyze the meaning and scope of social responsibility in a state-owned enterprise. Is corporate social responsibility (CSR) a meaningful concept for a state-owned enterprise, as opposed to a privately-owned corporation, given that it is created with social as well as economic aims? To try to answer to this question, the case of Sonatrach, an Algerian oil company, is examined. The lack of statistical data does not allow an assessment of CSR actions undertaken by (...) this company since 2004. The analysis identifies two main obstacles to the effectiveness of CSR in state-owned enterprises: (a) the system of internal governance ischaracterized by a lack of control; (b) the competitive and social environment is characterized by a partial application of the logic of the market, which does not allow the optimal allocation of means.

Haṭhayoga texts, influential in the development of modern posture-based yoga, offer a conceptual framework intertwining physical cultivation, health, and soteriological aims. This article explores two interconnected inquiries regarding early Haṭhayoga texts: How do they conceptualize health, and how do they perceive the relationship between health and soteriology? These investigations illuminate the place of health in early yoga texts within Hindu traditions prior to its global recognition. This article reveals that early _haṭha_ texts present a holistic approach to health, highlighting the (...) interconnectedness of curing the mind and healing the body. This process entails not only eradicating physical diseases but also the transcendence of all forms of suffering. The transformative process of eliminating the misleading self-identity (_ahaṁkāra_) is pivotal, leading directly to health. This relationship extends beyond metaphorical comparisons of healing ignorance and suffering. This ontological framework proposes a harmonious integration between the material and soteriological realms, viewing the healthy body as a physical manifestation of the divine essence. Thus, the emergence of the biomedical discourse surrounding yoga in modern times did not occur autonomously. Haṭhayoga, with its roots dating back to the beginning of the second millennium CE, played a crucial role in shaping this historical transformation. (shrink)

One defining feature of the Hindu religious worldviews is a belief in the impermanence of the body and its perception as a source of suffering due to a misguided attachment of the self to its corporeal manifestation. This view is expressed in several important traditions, including classical yoga, which perceives the physical body as an impediment to attaining liberation and irrelevant in the state of liberation.However, the perception of the physical body in liberation is going through ontological changes in early (...) medieval Haṭhayoga texts. The dichotomy between embodied and disembodied states of the body when one is liberated is the focus of this article. In several medieval yoga texts dating between the eleventh and the fifteenth centuries, the ontological immortal state of living liberation is more similar to physical death. Often the exact text holds both views of embodied and disembodied states simultaneously with no overt inconsistency. I argue that these tensions and contradictions can be explained in two ways: by looking at the assessed timeline of the texts and by reflecting on their sectarian and social origin. (shrink)

Quantum computers are hypothetical quantum information processing (QIP) devices that allow one to store, manipulate, and extract information while harnessing quantum physics to solve various computational problems and do so putatively more efficiently than any known classical counterpart. Despite many ‘proofs of concept’ (Aharonov and Ben–Or 1996; Knill and Laflamme 1996; Knill et al. 1996; Knill et al. 1998) the key obstacle in realizing these powerful machines remains their scalability and susceptibility to noise: almost three decades after their conceptions, experimentalists (...) still struggle to maintain useful quantum coherence in QIP devices with more than a pair of qubits (e.g., Blatt and Wineland 2008). This slow progress has prompted debates on the feasibility of quantum computers, yet the quantum information community has dismissed the skepticism as “ideology” (Aaronson 2004), claiming that the obstacles are merely technological (Kaye et al. 2007, 240). In a recent paper (Hagar 2009) I’ve argued that such a skepticism with respect to the feasibility of quantum computers need not be deemed ideological at all, and that the aforementioned ‘proofs of concept’ are physically suspect. Using analogies from the foundations of classical statistical mechanics (SM), I’ve also argued that instead of active error correction, the appropriate framework for debating the feasibility of large–scale, fault–tolerant and computationally superior quantum computers should be the project of error avoidance: rather than trying to constantly ‘cool down’ the QIP device and prevent its thermalization, one should try to locate those regions in the device’s state space which are thermodynamically ‘abnormal’, i.e., those regions in the device’s state space which resist thermalization regardless of external noise. This paper is intended as a further contribution to the debate on the feasibility of large–scale, fault–tolerant and computationally superior quantum computers. Relying again on analogies from the foundations of classical SM, it suggests a skeptical conjecture and frames it in the ‘passive’, error avoidance, context.. (shrink)

Le cri que porte l'intitulé de cet ouvrage est un appel aux lecteurs et aux historiens du Rushdisme à une halte réflexive sur ce que l'auteur appelle cri. Car le cri est une revendication légitime du philosophe. C'est une sorte de voix extra temporelle qui, par fidélité à l'esprit de sa philosophie, s'insurge et déclare que sa pensée a été trahie. Qui est donc ce philosophe à qui on a prêté tant de légendes et commis à son égard tant d'erreurs? (...) Est-ce un grand philosophe réduit au statut de simple commentateur? Ou est-ce une grande méprise à l'égard d'un penseur dont le seul tort est d'avoir voulu sauver le rationalisme philosophique? C'est avec force et détermination que l'auteur de cet essai nous démontre ses convictions sur un personnage historique essentiel, manifestement trop méconnu...

Buildings energy consumption is growing gradually and put away around 40% of total energy use. Predicting heating and cooling loads of a building in the initial phase of the design to find out optimal solutions amongst different designs is very important, as ell as in the operating phase after the building has been finished for efficient energy. In this study, an artificial neural network model was designed and developed for predicting heating and cooling loads of a building based on a (...) dataset for building energy performance. The main factors for input variables are: relative compactness, roof area, overall height, surface area, glazing are a, wall area, glazing area distribution of a building, orientation, and the output variables: heating and cooling loads of the building. The dataset used for training are the data published in the literature for various 768 residential buildings. The model was trained and validated, most important factors affecting heating load and cooling load are identified, and the accuracy for the validation was 99.60%. (shrink)

Evidential Decision Theory is a radical theory of rational decision-making. It recommends that instead of thinking about what your decisions *cause*, you should think about what they *reveal*. This Element explains in simple terms why thinking in this way makes a big difference, and argues that doing so makes for *better* decisions. An appendix gives an intuitive explanation of the measure-theoretic foundations of Evidential Decision Theory.

Drawing on feminist and queer critiques that see violence as constitutive of identities, this essay points to subject-positions whose construction is necessarily conditioned by exercising violence. Focusing on settler colonialism, I reverse the optics of the first set of critiques: rather than seeing the self as taking form through the injuries she suffers, I try to understand selves that are structurally constituted by causing injury to others. This analysis refuses the assumption that violence is in conflict with (liberal) identity, and (...) that, therefore, the endurance of violence of liberal states/societies is dependent upon mechanisms of active blindness (or denial, deferral, and other forms of dissociation). I argue that this assumption, which is shared by many critiques of violence, fails to perceive that people can desire the violent arrangements supporting their communities. They therefore fail to address political settings wherein violence is an affirmative element of political identities. (shrink)

For many among the scientifically informed public, and even among physicists, Heisenberg's uncertainty principle epitomizes quantum mechanics. Nevertheless, more than 86 years after its inception, there is no consensus over the interpretation, scope, and validity of this principle. The aim of this chapter is to offer one such interpretation, the traces of which may be found already in Heisenberg's letters to Pauli from 1926, and in Dirac's anticipation of Heisenberg's uncertainty relations from 1927, that stems form the hypothesis of finite (...) nature. Instead of a mere mathematical theorem of quantum theory, or a manifestation of "wave-particle duality", the uncertainty relations turn out to be a result of a more fundamental premise, namely, the inherent limitation on spatial resolution that follows from the bound on physical resources. The implication of this view are far reaching: it depicts the Hilbert space formalism as a phenomenological, "effective", formalism that approximates an underlying discrete structure; it supports a novel interpretation of probability in statistical physics that sees probabilities as deterministic, dynamical transition probabilities which arise from objective and inherent measurement errors; and it helps to clarify several puzzles in the foundations of statistical physics, such as the status of the "disturbance" view of measurement in quantum theory, or the tension between ontology and epistemology in the attempts to describe nature with physical theories whose formalisms include subjective probabilities. Finally, this view also renders obsolete the entire class of interpretations of quantum theory that adhere to "the reality of the wave function". (shrink)

An analysis of the two routes through which one may disentangle a quantum system from a measuring apparatus, hence protect the state vector of a single quantum system from being disturbed by the measurement, reveals several loopholes in the argument from protective measurement to the reality of the state vector of a single quantum system.

One of the recurrent problems in the foundations of physics is to explain why we rarely observe certain phenomena that are allowed by our theories and laws. In thermodynamics, for example, the spontaneous approach towards equilibrium is ubiquitous yet the time-reversal-invariant laws that presumably govern thermal behaviour in the microscopic level equally allow spontaneous departure from equilibrium to occur. Why are the former processes frequently observed while the latter are almost never reported? Another example comes from quantum mechanics where the (...) formalism, if considered complete and universally applicable, predicts the existence of macroscopic superpositions—monstrous Schr¨odinger cats—and these are never observed: while electrons and atoms enjoy the cloudiness of waves, macroscopic objects are always localized to definite positions.

Scientific realism is dead, or so many philosophers believe. Its death was announced when philosophers became convinced that one can accept all scientific results without committing oneself to metaphysical existence claims about theoretical entities (Fine 1986, 112). In addition, the inability of self–proclaimed scientific realists, despite recurrent demands, to distinguish themselves from their rival anti–realists (Stein 1989) didn’t exactly help their cause. If realists cannot identify the key feature or features that set them apart from their opponents, then there is (...) really no need to conduct a debate on scientific realism, is there? (shrink)

Abstract: Background: In spite of the fact that computers continue to improve in speed and functions operation, they remain complex to use. Problems frequently happen, and it is hard to resolve or find solutions for them. This paper outlines the significance and feasibility of building a desktop PC problems diagnosis system. The system gathers problem symptoms from users’ desktops, rather than the user describes his/her problems to primary search engines. It automatically searches global databases of problem symptoms and solutions, and (...) also allows ordinary users to contribute exact problem reports in a structured manner. Objectives: The main goal of this Knowledge Based System is to get the suitable problem desktop PC symptoms and the correct way to solve the errors. Methods: In this paper the design of the proposed Knowledge Based System which was produced to help users of desktop PC in knowing many of the problems and error such as : Power supply problems, CPU errors, RAM dumping error, hard disk errors and bad sectors and suddenly restarting PC. The proposed Knowledge Based System presents an overview about desktop PC hardware errors are given, the cause of fault are outlined and the solution to the problems whenever possible is given out. CLIPS Knowledge Based System language was used for designing and implementing the proposed expert system. Results: The proposed PC desktop troubleshooting Knowledge Based System was evaluated by IT students and they were satisfied with its performance. (shrink)
