A Neural Probabilistic Graphical Model for Learning and Decision Making in Evolving Structured Environments

open access: yesMathematics, 2022
A difficult and open problem in artificial intelligence is the development of agents that can operate in complex environments which change over time. The present communication introduces the formal notions, the architecture, and the training algorithm of

Density Estimation Through Convex Combinations of Densities: Approximation and Estimation Bounds [PDF]

open access: yesNeural Networks, 1997
We consider the problem of estimating a density function from a sequence identically distributed observations x(i) taking value in X subset R(d). The estimation procedure constructs a convex mixture of "basis" densities and estimates the parameters using the maximum likelihood method.

An assessment of sampling designs using SCR analyses to estimate abundance of boreal caribou

open access: yesEcology and Evolution, 2020
Accurately estimating abundance is a critical component of monitoring and recovery of rare and elusive species. Spatial capture–recapture (SCR) models are an increasingly popular method for robust estimation of ecological parameters.

Local density estimation for VANETs [PDF]

open access: yes2016 Global Information Infrastructure and Networking Symposium (GIIS), 2016
Local vehicle density estimation is an integral part of various applications of Vehicular Ad-hoc Networks (VANETs) such as congestion control and congestion traffic estimation. Currently, many applications use beacons to estimate this density. However, many studies show that the reception rate of these beacons can significantly drop at short distances ...

msBP: An R Package to Perform Bayesian Nonparametric Inference Using Multiscale Bernstein Polynomials Mixtures

open access: yesJournal of Statistical Software, 2017
msBP is an R package that implements a new method to perform Bayesian multiscale nonparametric inference introduced by Canale and Dunson (2016). The method, based on mixtures of multiscale beta dictionary densities, overcomes the drawbacks of Pólya trees

Approximate inference of the bandwidth in multivariate kernel density estimation [PDF]

open access: yes, 2011
Kernel density estimation is a popular and widely used non-parametric method for data-driven density estimation. Its appeal lies in its simplicity and ease of implementation, as well as its strong asymptotic results regarding its convergence to the true ...

Evaluating the Use of Drones Equipped with Thermal Sensors as an Effective Method for Estimating Wildlife

open access: yesWildlife Society Bulletin, 2020
Drones equipped with thermal sensors have shown ability to overcome some of the limitations often associated with traditional human‐occupied aerial surveys (e.g., low detection, high operational cost, human safety risk).

Estimation of Densities and Applications

open access: yesJournal of Theoretical Probability, 1998
In this paper we show some estimates for the density of a random variable on the Wiener space that satisfies a nondegeneracy condition using the stochastic calculus of variations. The case of a diffusion process is considered, and an application to the solution of a stochastic partial differential equation is discussed.
