Relational discriminant analysis and its large sample size problem
Relational discriminant analysis is based on a similarity matrix of the training set. It is able to construct reliable nonlinear discriminants in infinite dimensional feature spaces based on small training sets. This technique has a large sample size problem as the size of the similarity matrix equals the square of the number of objects in the training set. In this paper we discuss and initiall...
متن کاملWhy Believe That There Is a God?
This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...
متن کاملIs There a Monopole Problem ?
We show that there exists a range of parameters in SU(5) theory for which the GUT symmetry remains broken at high temperature, thus avoiding the phase transition that gives rise to the overproduction of monopoles. The thermal production of monopoles can be naturally suppressed, keeping their number density below the cosmological limits. A. Introduction It has been known for a long time that the...
متن کاملVitamin D: Is There a New Era?
Background: In recent decades, much interest has been focused on investigating new roles of vitamin D in human body beyond the mineral-ion homeostasis. Methods: By searching medical databases such as PubMed, over 16000 articles were found which have been published since 2000 on novel aspects of vitamin D in health and diseases. Results: Of great interest was the effects of vitamin D on ...
متن کاملA mixed Bayesian/Frequentist approach in sample size determination problem for clinical trials
In this paper we introduce a stochastic optimization method based ona mixed Bayesian/frequentist approach to a sample size determinationproblem in a clinical trial. The data are assumed to come from a nor-mal distribution for which both the mean and the variance are unknown.In contrast to the usual Bayesian decision theoretic methodology, whichassumes a single decision maker, our method recogni...
