Running head: OCKHAM’S RAZOR AND PERCEPTION Perceptual Judgment Obeys Ockham’s Razor
Theoretical models of unsupervised category learning postulate that humans “invent” categories to accommodate new patterns, but tend to group stimuli into a small number of categories. This “Ockham’s razor” principle is motivated by normative rules of statistical inference. If categories influence perception, then one should find effects of category invention on simple perceptual judgments. In ...
متن کاملOccam's Razor
The Bayesian paradigm apparently only sometimes gives rise to Occam’s Razor; at other times very large models perform well. We give simple examples of both kinds of behaviour. The two views are reconciled when measuring complexity of functions, rather than of the machinery used to implement them. We analyze the complexity of functions for some linear in the parameter models that are equivalent ...
متن کاملSharpening Occam's Razor
We provide a new representation-independent formulation of Occam’s razor theorem, based on Kolmogorov complexity. This new formulation allows us to: (i) Obtain better sample complexity than both length-based [4] and VC-based [3] versions of Occam’s razor theorem, in many applications; and (ii) Achieve a sharper reverse of Occam’s razor theorem than that of [5]. Specifically, we weaken the assum...
متن کاملExtending Occam's Razor
Occam's Razor states that, all other things being equal, the simpler of two possible hypotheses is to be preferred. A quanti ed version of Occam's Razor has been proven for the PAC model of learning, giving sample-complexity bounds for learning using what Blumer et al. call an Occam algorithm [1]. We prove an analog of this result for Haussler's more general learning model, which encompasses le...
متن کاملOn Occam's Razor
\Occam's Razor" is an important metatheoretical principle in science. Mathematical methods from ergodic theory, information theory, and the theory of algorithms and stochastic processes can be used to help clarify the meaning of Occam's Razor and address the philosophical problems it raises. 1 1 \Pluralitas non est ponenda sine nec-cesitate." Thus, William of Occam articulated the famous princi...
