Why Occam’s Razor
In this paper, I show why in an ensemble theory of the universe, we should be inhabiting one of the elements of that ensemble with least information content that satisfies the anthropic principle. This explains the effectiveness of aesthetic principles such as Occam’s razor in predicting usefulness of scientific theories. I also show, with a couple of reasonable assumptions about the phenomenon...
متن کاملWhy Nitpicking Works: Evidence for Occam's Razor in Error Correctors
Empirical experience and observations have shown us when powerful and highly tunable classifiers such as maximum entropy classifiers, boosting and SVMs are applied to language processing tasks, it is possible to achieve high accuracies, but eventually their performances all tend to plateau out at around the same point. To further improve performance, various error correction mechanisms have bee...
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 کاملApplying Occam's razor to paper (and rock and scissors, too): Why simpler models are sometimes better
A commonly held idea is that people engaged in guessing tasks try to detect sequential dependencies between the occurring events and behave accordingly. For instance, previous accounts of the popular Rock Paper Scissors game assume that people try to anticipate the move an opponent is likely to make and play a move capable of beating it. In the paper we propose that players modulate their behav...
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...
