Mixture multilevel vector-autoregressive modeling [PDF]
The modeling techniques for intensive longitudinal data are increasingly focused on individual differences.In my talk I will present mixture multilevel vector-autoregressive modeling, which extends multilevel vectorautoregressive modeling by including a ...

On Choosing a Mixture Model for Clustering [PDF]
2 Universit e de Caen Abstract: Two methods for clustering data and choosing a mixture model are proposed. First, we derive a new classication algorithm based on the classication likelihood. Then, the likelihood conditional on these clusters is written as the product of likelihoods of each cluster, and AIC- respectively BIC-type approximations are ...

Graph Laplacian Mixture Model [PDF]
Graph learning methods have recently been receiving increasing interest as means to infer structure in datasets. Most of the recent approaches focus on different relationships between a graph and data sample distributions, mostly in settings where all available data relate to the same graph.

A family of mixture models for biclustering [PDF]
AbstractBiclustering is used for simultaneous clustering of the observations and variables when there is no group structure known a priori. It is being increasingly used in bioinformatics, text analytics, and so on. Previously, biclustering has been introduced in a model‐based clustering framework by utilizing a structure similar to a mixture of factor

Partitioning Pervasive Detrital Geochronologic Age Distributions in the Southern Alaskan Forearc
The extensive detrital zircon U-Pb geochronologic dataset presented here includes new and compiled data (N = 38; n = 8,006) from modern rivers that together comprehensively characterizes the geographic distribution of pervasive Mesozoic—Cenozoic igneous ...

Deep Gaussian mixture models [PDF]
Deep learning is a hierarchical inference method formed by subsequent multiple layers of learning able to more efficiently describe complex relationships. In this work, Deep Gaussian Mixture Models are introduced and discussed. A Deep Gaussian Mixture model (DGMM) is a network of multiple layers of latent variables, where, at each layer, the variables ...

Estimating propensity scores with missing covariate data using general location mixture models
In many observational studies, researchers estimate causal effects using propensity scores, e.g., by matching or sub-classifying on the scores. Estimation of propensity scores is complicated when some values of the covariates aremissing.

Video foreground detection based on symmetric alpha-stable mixture models. [PDF]
Background subtraction (BS) is an efficient technique for detecting moving objects in video sequences. A simple BS process involves building a model of the background and extracting regions of the foreground (moving objects) with the assumptions that the

Exploring Class Enumeration in Bayesian Growth Mixture Modeling Based on Conditional Medians
Growth mixture modeling is a popular analytic tool for longitudinal data analysis. It detects latent groups based on the shapes of growth trajectories.
