Two-point correlation properties of stochastic "cloud processes'' [PDF]

open access: yes, 2007
We study how the two-point density correlation properties of a point particle distribution are modified when each particle is divided, by a stochastic process, into an equal number of identical "daughter" particles. We consider generically that there may

Procesos puntuales, densidades producto y biología celular

open access: yesRevista Colombiana de Estadística, 2005
En este artículo se explica cómo los procesos puntuales han sido usados con éxito para modelar problemas de poblaciones celulares. En particular, se muestra la utilidad de la técnica de densidades producto para tratar un problema de células sujetas a ...

Local Central Limit Theorem for Determinantal Point Processes [PDF]

open access: yes, 2014
We prove a local central limit theorem (LCLT) for the number of points $N(J)$ in a region $J$ in $\mathbb R^d$ specified by a determinantal point process with an Hermitian kernel.

Poisson approximation of binomial point processes [PDF]

open access: yesE3S Web of Conferences
In the paper, we study properties of the vertex process from convex hulls generated by independent observations of a two-dimensional random vector, the distribution of which behaves like a regularly varying function near the boundary of the support of ...

User Point Processes in Cellular Networks [PDF]

open access: yesIEEE Wireless Communications Letters, 2016
The point process of concurrent users is critical for the analysis of cellular systems, in particular for the uplink and for full-duplex communication. We analyze the properties of two popular models.

Monte Carlo with determinantal point processes [PDF]

open access: yesThe Annals of Applied Probability, 2016
We show that repulsive random variables can yield Monte Carlo methods with faster convergence rates than the typical $N^{-1/2}$, where $N$ is the number of integrand evaluations.

Cumulants of Hawkes point processes

open access: yes, 2015
We derive explicit, closed-form expressions for the cumulant densities of a multivariate, self-exciting Hawkes point process, generalizing a result of Hawkes in his earlier work on the covariance density and Bartlett spectrum of such processes.

The Extreme Value Support Measure Machine for Group Anomaly Detection

open access: yesMathematics
Group anomaly detection is a subfield of pattern recognition that aims at detecting anomalous groups rather than individual anomalous points. However, existing approaches mainly target the unusual aggregate of points in high-density regions. In this way,

NETWORK DETECTION IN RASTER DATA USING MARKED POINT PROCESSES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
We propose a new approach for the automatic detection of network structures in raster data. The model for the network structure is represented by a graph whose nodes and edges correspond to junction-points and to connecting line segments, respectively ...
