Anti-Clutter Gaussian Inverse Wishart PHD Filter for Extended Target Tracking [PDF]
The extended target Gaussian inverse Wishart probability hypothesis density (ET-GIW-PHD) filter overestimates the number of targets under high clutter density. The reason for this is that the source of measurements cannot be determined correctly if only the number of measurements is used. To address this problem, we proposed an anti-clutter filter with

Parametric Bayesian Estimation of Differential Entropy and Relative Entropy
Given iid samples drawn from a distribution with known parametric form, we propose the minimization of expected Bregman divergence to form Bayesian estimates of differential entropy and relative entropy, and derive such estimators for the uniform ...

Probabilistic Clustering Using Multivariate Growth Mixture Model in Clinical Settings-A Scleroderma Example. [PDF]
ABSTRACT Background Scleroderma (systemic sclerosis; SSc) is a chronic autoimmune disease known for wide heterogeneity in patients' disease progression in multiple organ systems. Our goal is to guide clinical care by real‐time classification of patients into clinically interpretable subpopulations based on their baseline characteristics and the ...

On the asymptotic and approximate distributions of the product of an inverse Wishart matrix and a Gaussian vector [PDF]
In this paper we study the distribution of the product of an inverse Wishart random matrix and a Gaussian random vector. We derive its asymptotic distribution as well as its approximate density function formula which is based on the Gaussian integral and the third order Taylor expansion.

Spatial joint modelling of multivariate longitudinal outcomes and cure proportion using latent Gaussian model with application to dataset on HIV/AIDS patients [PDF]
Survival analysis has seen in recent times more of joint modelling of longitudinal and survival data using approximate hierarchical Bayesian method. This study modelled jointly multivariate and cure proportion with spatial variation using latent Gaussian

Robust adaptive multi‐target tracking with unknown measurement and process noise covariance matrices
A robust adaptive probability hypothesis density (PHD) filter is proposed to address the degradation of PHD performance due to an unknown process noise and measurement noise covariance matrix.

Poisson multi‐Bernoulli mixture filters with coloured measurement noise
To solve multitarget tracking (MTT) problems with coloured measurement noise, this study proposes a Poisson multi‐Bernoulli mixture filter with coloured measurement noise (PMBM‐CMN) and a robust PMBM‐CMN filter.
