Bayesian methods for hierarchical distance sampling models [PDF]

open access: yes, 2014
Cornelia S. Oedekoven was supported by a studentship jointly funded by the University of St Andrews and EPSRC (EPSRC grant EP/C522702/1), through the National Centre for Statistical Ecology.The few distance sampling studies that use Bayesian methods ...

Hierarchical Models in the Brain

open access: yesPLoS Computational Biology, 2008
This paper describes a general model that subsumes many parametric models for continuous data. The model comprises hidden layers of state-space or dynamic causal models, arranged so that the output of one provides input to another. The ensuing hierarchy furnishes a model for many types of data, of arbitrary complexity.

Visualizing classification of natural video sequences using sparse, hierarchical models of cortex. [PDF]

open access: yes, 2011
Recent work on hierarchical models of visual cortex has reported state-of-the-art accuracy on whole-scene labeling using natural still imagery. This raises the question of whether the reported accuracy may be due to the sophisticated, non-biological

Fixed or random? On the reliability of mixed‐effects models for a small number of levels in grouping variables

open access: yesEcology and Evolution, 2022
Biological data are often intrinsically hierarchical (e.g., species from different genera, plants within different mountain regions), which made mixed‐effects models a common analysis tool in ecology and evolution because they can account for the non ...

Grand Canonical Ensembles of Sparse Networks and Bayesian Inference

open access: yesEntropy, 2022
Maximum entropy network ensembles have been very successful in modelling sparse network topologies and in solving challenging inference problems. However the sparse maximum entropy network models proposed so far have fixed number of nodes and are ...

Neural hierarchical models of ecological populations

open access: yesbioRxiv, 2019
Neural networks are increasingly being used in science to infer hidden dynamics of natural systems from noisy observations, a task typically handled by hierarchical models in ecology.

Hierarchical graphical bayesian models in psychology [PDF]

open access: yes, 2014
The improvement of graphical methods in psychological research can promote their use and a better comprehension of their expressive power. The application of hierarchical Bayesian graphical models has recently become more frequent in psychological ...

Analysis of criteria system model for construction contract evaluation

open access: yesTechnological and Economic Development of Economy, 2007
A number of multicriteria decisions must be made during construction investment processes. A number of support systems for multicriteria tasks of construction investment processes are available. Part of them is reviewed in this article.

Uncovering the heterogeneity of a solar flare mechanism with mixture models

open access: yesFrontiers in Astronomy and Space Sciences
The physics of solar flares occurring on the Sun is highly complex and far from fully understood. However, observations show that solar eruptions are associated with the intense kilogauss fields of active regions, where free energies are stored with ...
