Hyperspectral and Multispectral Image Fusion via Deep Generalised Linear Mixed Model
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Hyperspectral–multispectral image fusion is an incomplete information fusion problem, and directly embedding information can lead to modality‐specific responses and cause spectral distortion, whereas the strong interband redundancy of hyperspectral images makes full‐dimensional fusion inefficient.

Clustering and unconstrained ordination with Dirichlet process mixture models
Methods in Ecology and EvolutionAssessment of similarity in species composition or abundance across sampled locations is a common goal in multi‐species monitoring programs. Existing ordination techniques provide a framework for clustering sample locations based on species composition ...

Dirichlet Process Mixture Model with Spatial Constraints
, 2007 Dirichlet process (DP) provides a nonparametric prior for the mixture model that allows for the automatic detection of the number of hidden states. Recent introduction of variational Bayesian (VB) inference as a deterministic approach makes it practical ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Improved use of deep soil water promotes radial growth during drought
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Increasingly frequent seasonal droughts under rapid climate change threaten the growth stability of subtropical mixed forests across the mid‐subtropical monsoon region.

Journal of Forensic Sciences, EarlyView.Abstract Skeletal age estimation is crucial to medicolegal work, aiding subadult identification, and living age assessments in legal contexts. This study aims to document the ontogeny of knee skeletal indicators on post‐mortem computed tomography (PMCT), and quantify interpopulation variation between modern American and Australian children.

A Special Dirichlet Mixture Model for Multivariate Bounded Responses
, 2017 The purpose of this paper is to provide a new regression model for multivariate continuous variables with bounded support, by taking into consideration the flexible Dirichlet, which is a special mixture of Dirichlet ...

Estimating absolute DNA abundance from replicated metabarcoding
Methods in Ecology and Evolution, EarlyView.Abstract Datasets derived from mixed‐template DNA amplification and sequencing (‘metabarcoding’) are common in environmental DNA (eDNA), microbiome or microbial ecology analyses. Such metabarcoding data have been broadly used to inform estimates of biodiversity, distribution and abundance across a wide range of species and habitats.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...
