Generalised Measures of Multivariate Information Content

open access: yesEntropy, 2020
The entropy of a pair of random variables is commonly depicted using a Venn diagram. This representation is potentially misleading, however, since the multivariate mutual information can be negative.

Applying free random variables to random matrix analysis of financial data. Part I: The Gaussian case

open access: yes, 2010
We apply the concept of free random variables to doubly correlated (Gaussian) Wishart random matrix models, appearing, for example, in a multivariate analysis of financial time series, and displaying both inter-asset cross-covariances and temporal auto ...

A permutation model for free random variables and its classical analogue

open access: yes, 2009
International audienceIn this paper, we generalize a permutation model for free random variables which was first proposed by Biane. We also construct its classical probability analogue, by replacing the group of permutations with the group of subsets of ...

Chronic back pain sub-grouped via psychosocial, brain and physical factors using machine learning

open access: yesScientific Reports, 2022
Chronic back pain (CBP) is heterogenous and identifying sub-groups could improve clinical decision making. Machine learning can build upon prior sub-grouping approaches by using a data-driven approach to overcome clinician subjectivity, however, only ...

Zero Distribution of System with Unknown Random Variables Case Study: Avoiding Collision Path

open access: yesMATEC Web of Conferences, 2014
This paper presents the stochastic analysis of finding the feasible trajectories of robotics arm motion at obstacle surrounding. Unknown variables are coefficients of polynomials joint angle so that the collision-free motion is achieved.

Variability in mRNA translation: a random matrix theory approach

open access: yesScientific Reports, 2021
The rate of mRNA translation depends on the initiation, elongation, and termination rates of ribosomes along the mRNA. These rates depend on many “local” factors like the abundance of free ribosomes and tRNA molecules in the vicinity of the mRNA molecule.

Limit laws for products of free and independent random variables [PDF]

open access: yesStudia Mathematica, 2000
The free independence as a noncommutative analog of the classical notion of independence in probability theory is considered. In the paper the authors study the parallelism between freenes and independence for products of positive random variables. The results of the paper are written in terms of convolutions.
