NML, Bayes and True Distributions: A Comment on Karabatsos and Walker (2006)
We review the normalized maximum likelihood (NML) criterion for selecting among competing models. NML is generally justified on information-theoretic grounds, via the principle of minimum description length (MDL), in a derivation that “does not assume the existence of a true, data-generating distribution.” Since this “agnostic” claim has been a source of some recent confusion in the psychologic...
متن کاملFast NML Computation for Naive Bayes Models
The Minimum Description Length (MDL) is an informationtheoretic principle that can be used for model selection and other statistical inference tasks. One way to implement this principle in practice is to compute the Normalized Maximum Likelihood (NML) distribution for a given parametric model class. Unfortunately this is a computationally infeasible task for many model classes of practical impo...
متن کاملpersian true and false cognates in english: students and teachers’ attitudes, awareness, and instruction
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
on semihypergroups and hypergroups
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
15 صفحه اولBayes Factors and BIC Comment on Weakliem
Weakliem agrees that Bayes factors are useful for model selection and hypothesis testing He reminds us that the simple and convenient BIC approximation corresponds most closely to one particular prior on the parameter space the unit information prior and points out that researchers may have di erent prior information or opinions Clearly a prior that represents the available information should b...
