ESTIMATES OF FACTORS DIRECTLY RELATED TO FINE ROOT LONGEVITY USING A HIERARCHICAL BAYESIAN MODEL by

Fine root longevity, measured using minirhizotrons, range from days to years (Hendrick & Pregitzer, 1992; Eissenstat et al., 2000). Although there are several hypotheses that relate to root tissue lifespan (Ryser, 1996), very few long-term studies have examined the factors that may be directly related to survivorship of individual roots. It is known that atmospheric CO2, which is the major gree...

Bayesian Modeling of Dependency Trees Using Hierarchical Pitman-Yor Priors

Recent work in hierarchical priors for language modeling [MacKay and Peto, 1994, Teh, 2006, Goldwater et al., 2006] has shown significant advantages to Bayesian methods in NLP. But the issue of sparse conditioning contexts is ubiquitous in NLP, and these smoothing ideas can be applied more broadly to extend the reach of Bayesian modeling in natural language. For example, a useful representation...

A Bayesian hierarchical model for allele frequencies.

Genetic epidemiological methodologies, such as linkage analysis, often require accurate estimates of allele frequencies. When studies involve multiple sub-populations with different evolutionary histories, accurate estimates can be difficult to obtain because the number of subjects per sub-population tends to be limited. Given allele counts for a collection of loci and sub-populations, we propo...

A Bayesian Hierarchical Model for Photometric Redshifts

The Sloan Digital Sky Survey (SDSS) is an extremely large astronomical survey conducted with the intention of mapping more than a quarter of the sky (http://www.sdss.org/). Among the data it is generating are spectroscopic and photometric measurements, both allowing estimation of the redshift of galaxies. The former is precise but expensive to gather, the latter is far cheaper but corresponding...

A Hierarchical Bayesian Model for Topic Segmentation

Many streams of real-world data, such as conversations or body movements, consist of relatively coherent segments, each characterized by particular topics or controllers. Making sense of these data requires simultaneously segmenting the sequences and inferring the structure of the segments. We present a hierarchical Bayesian model that can be used to break a sequence of utterances or movements ...
