Least-Variable Harmonic Matrix-Exponential Distributions
Maria Laura Battagliola, Oscar Peralta
Concentrated matrix-exponential (CME) distributions are random clocks approximating a fixed time, with quality measured by the squared coefficient of variation (SCV); a well-known…
Least Variability in a Polynomial-Square Class of Rational Kernels
Maria Laura Battagliola, Oscar Peralta
We solve an extremal problem for positive randomization kernels that concentrate a random time as tightly as possible around a deterministic target, within the class obtained by ex…
Colored Markov-Modulated Brownian Motion for Preemptive Workload Stacks
Maria Laura Battagliola, Eduardo Medina-Valdés, Oscar Peralta
We develop a colored Markov-modulated Brownian motion model for diffusion-scale systems in which newly created work preempts the active layer, occupies the top of an ordered stack,…
Local Second-Order Geometry Induced by Deformation Maps
Maria Laura Battagliola
Spatial deformations offer a flexible route to nonstationary dependence by warping the coordinates of a stationary random field. While the exact induced covariance depends on the d…
Optimization-Free Concentrated Matrix-Exponentials
Maria Laura Battagliola, Oscar Peralta
Near-deterministic positive delays require highly concentrated distributions, but phase-type models are constrained by the Erlang variance limit. While matrix-exponential distribut…
Functional Modeling of Learning and Memory Dynamics in Cognitive Disorders
Maria Laura Battagliola, Laura J. Benoit, Sarah Canetta +2
Deficits in working memory, which includes both the ability to learn and to retain information short-term, are a hallmark of many cognitive disorders. Our study analyzes data from…
