Variational Bayesian Method for Retinex
IEEE Transactions on Image Processing, 2014In this paper, we propose a variational Bayesian method for Retinex to simulate and interpret how the human visual system perceives color. To construct a hierarchical Bayesian model, we use the Gibbs distributions as prior distributions for the reflectance and the illumination, and the gamma distributions for the model parameters.

A Variation on a Nonparametric Clustering Method
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1979A single modification to a mode-seeking clustering algorithm proposed by Koontz, Narendra, and Fukunaga is shown to generate a novel clustering and to provide an indication of cluster stability. The modified method should provide better clusterings for ``uniform, touching'' clusters than the original, although the original should work better than the ...

Variational method in a heterojunction
Physical Review B, 1991Determination des expressions analytiques de l'energie de l'etat fondamental et de la 1ere sous-bande d'une heterojonction en fonction de la temperature et de la concentration en electrons. La difference d'energie E 10 entre la premiere sous-bande et l'etat fondamental est en accord raisonnable avec les donnees obtenues dans une heterojonction GaAs-Ga

MODIFICATIONS TO THE VARIATE-DIFFERENCE METHOD
Biometrika, 19531-2. The variate-difference method (Anderson, 1914) is closely related to the method of moving averages, and may be regarded as having greater generality. Any moving average difference formula may be shown to be equivalent to an average of higher order differences and, consequently, results obtainable from such formulae may be obtained by ...

Six Variations on the Variational Method
1998As a graduate student in physics at the University of Michigan many years ago I had the good fortune to take a course in function theory from Norman Steenrod that pretty much changed the course of my life. My experience in that course plus several private conversations convinced me to switch out of physics and into mathematics.
