We have previously justified the use of the reduced function f(y)=CT(y)b(y), where C(y) is a matrix whose columns form an orthonormal basis for the nullspace of AT(y), and presented a quadratically convergent Gauss–Newton type method for solving miny. In this note, we show how LU factorization can replace the QR factorization in those computations, halving the associated computational cost while also providing opportunities to exploit sparsity and thus further enhance computational efficiency. Occam's razor - Wikipedia. Occam's razor (also Ockham's razor; Latin: lex parsimoniae . English Franciscan friar, scholastic philosopher, and theologian. His principle can be interpreted as stating Among competing hypotheses, the one with the fewest assumptions should be selected. In science, Occam's razor is used as a heuristic guide in the development of theoretical models, rather than as a rigorous arbiter between candidate models. For each accepted explanation of a phenomenon, there may be an extremely large, perhaps even incomprehensible, number of possible and more complex alternatives, because one can always burden failing explanations with ad hoc hypotheses to prevent them from being falsified; therefore, simpler theories are preferable to more complex ones because they are more testable. Libert Froidmont, in his On Christian Philosophy of the Soul, takes credit for the phrase, speaking of . AD 1. 68) stated, . For if one thing were demonstrated from many and another thing from fewer equally known premises, clearly that is better which is from fewer because it makes us know quickly, just as a universal demonstration is better than particular because it produces knowledge from fewer premises. Similarly in natural science, in moral science, and in metaphysics the best is that which needs no premises and the better that which needs the fewer, other circumstances being equal. Aquinas uses this principle to construct an objection to God's existence, an objection that he in turn answers and refutes generally (cf. His popular fame as a great logician rests chiefly on the maxim attributed to him and known as Ockham's razor. The term razor refers to distinguishing between two hypotheses either by . Lugd., 1. 49. 5), i, dist. K). Nevertheless, the precise words sometimes attributed to Ockham, entia non sunt multiplicanda praeter necessitatem (entities must not be multiplied beyond necessity). Ockham's contribution seems to be to restrict the operation of this principle in matters pertaining to miracles and God's power: so, in the Eucharist, a plurality of miracles is possible, simply because it pleases God. Ockham cites the principle of economy, Frustra fit per plura quod potest fieri per pauciora (It is futile to do with more things that which can be done with fewer. Kneale and Kneale, 1. Later formulations. Therefore, to the same natural effects we must, as far as possible, assign the same causes. The only assumption is that the environment follows some unknown but computable probability distribution. This theory is a mathematical formalization of Occam's razor. This is considered a . This notion was deeply rooted in the aesthetic value that simplicity holds for human thought and the justifications presented for it often drew from theology. Thomas Aquinas made this argument in the 1. It is, however, often difficult to deduce which part of the data is noise (cf. Another interpretation of the razor's statement would be that . The procedure to test the former interpretation would compare the track records of simple and comparatively complex explanations. If one accepts the first interpretation, the validity of Occam's razor as a tool would then have to be rejected if the more complex explanations were more often correct than the less complex ones (while the converse would lend support to its use). If the latter interpretation is accepted, the validity of Occam's razor as a tool could possibly be accepted if the simpler hypotheses led to correct conclusions more often than not. It is coherent, for instance, to add the involvement of leprechauns to any explanation, but Occam's razor would prevent such additions unless they were necessary. In the history of competing hypotheses, the simpler hypotheses have led to mathematically rigorous and empirically verifiable theories. Some increases in complexity are sometimes necessary. So there remains a justified general bias toward the simpler of two competing explanations. To understand why, consider that for each accepted explanation of a phenomenon, there is always an infinite number of possible, more complex, and ultimately incorrect, alternatives. This is so because one can always burden failing explanations with ad hoc hypothesis. Ad hoc hypotheses are justifications that prevent theories from being falsified. Even other empirical criteria, such as consilience, can never truly eliminate such explanations as competition. Each true explanation, then, may have had many alternatives that were simpler and false, but also an infinite number of alternatives that were more complex and false. But if an alternate ad hoc hypothesis were indeed justifiable, its implicit conclusions would be empirically verifiable. On a commonly accepted repeatability principle, these alternate theories have never been observed and continue to escape observation. In addition, one does not say an explanation is true if it has not withstood this principle. Put another way, any new, and even more complex, theory can still possibly be true. For example, if an individual makes supernatural claims that leprechauns were responsible for breaking a vase, the simpler explanation would be that he is mistaken, but ongoing ad hoc justifications (e. This endless supply of elaborate competing explanations, called saving hypotheses, cannot be ruled out—except by using Occam's razor. None of the papers provided a balance of evidence that complexity of method improved forecast accuracy. In the 2. 5 papers with quantitative comparisons, complexity increased forecast errors by an average of 2. Philosopher Elliott Sober states that not even reason itself can be justified on any reasonable grounds, and that we must start with first principles of some kind (otherwise an infinite regress occurs). Though one may claim that Occam's razor is invalid as a premise that helps regulate theories, putting this doubt into practice would mean doubting whether every step forward will result in locomotion or a nuclear explosion. In other words: . By definition, all assumptions introduce possibilities for error; if an assumption does not improve the accuracy of a theory, its only effect is to increase the probability that the overall theory is wrong. There have also been other attempts to derive Occam's razor from probability theory, including notable attempts made by Harold Jeffreys and E. The probabilistic (Bayesian) basis for Occam's razor is elaborated by David J. Mac. Kay in chapter 2. Information Theory, Inference, and Learning Algorithms. Jefferys (no relation to Harold Jeffreys) and James O. Berger (1. 99. 1) generalize and quantify the original formulation's . This, again, reflects the mathematical relationship between key concepts in Bayesian inference (namely marginal probability, conditional probability, and posterior probability). Other philosophers. Our preference for simplicity may be justified by its falsifiability criterion: we prefer simpler theories to more complex ones . The idea here is that a simple theory applies to more cases than a more complex one, and is thus more easily falsifiable. This is again comparing a simple theory to a more complex theory where both explain the data equally well. Elliott Sober. He now believes that simplicity considerations (and considerations of parsimony in particular) do not count unless they reflect something more fundamental. Philosophers, he suggests, may have made the error of hypostatizing simplicity (i. Sober 1. 99. 2). If we fail to justify simplicity considerations on the basis of the context in which we use them, we may have no non- circular justification: . Since it is absurd to have no logical method for settling on one hypothesis amongst an infinite number of equally data- compliant hypotheses, we should choose the simplest theory: . That is the meaning of Occam's Razor.(If everything in the symbolism works as though a sign had meaning, then it has meaning.)4. In the proposition there must be exactly as many things distinguishable as there are in the state of affairs which it represents. They must both possess the same logical (mathematical) multiplicity (cf. Hertz's Mechanics, on Dynamic Models). Occam's Razor is, of course, not an arbitrary rule nor one justified by its practical success. It simply says that unnecessary elements in a symbolism mean nothing. Signs which serve one purpose are logically equivalent; signs which serve no purpose are logically meaningless. An often- quoted version of this constraint (which cannot be verified as posited by Einstein himself). However, science has shown repeatedly that future data often support more complex theories than do existing data. Science prefers the simplest explanation that is consistent with the data available at a given time, but the simplest explanation may be ruled out as new data become available. Several background assumptions are required for parsimony to connect with plausibility in a particular research problem. The reasonableness of parsimony in one research context may have nothing to do with its reasonableness in another. It is a mistake to think that there is a single global principle that spans diverse subject matter. There is little empirical evidence that the world is actually simple or that simple accounts are more likely to be true than complex ones. For example, Max Planck interpolated between the Wien and Jeans radiation laws and used Occam's razor logic to formulate the quantum hypothesis, even resisting that hypothesis as it became more obvious that it was correct. One can argue for atomic building blocks for matter, because it provides a simpler explanation for the observed reversibility of both mixing and chemical reactions as simple separation and rearrangements of atomic building blocks. At the time, however, the atomic theory was considered more complex because it implied the existence of invisible particles that had not been directly detected.
