Parametric matrix models [PDF]

Nature Communications
We present a general class of machine learning algorithms called parametric matrix models. In contrast with most existing machine learning models that imitate the biology of neurons, parametric matrix models use matrix equations that emulate physical ...

On matrix models and their q-deformations [PDF]

Journal of High Energy Physics, 2020
Motivated by the BPS/CFT correspondence, we explore the similarities be- tween the classical β-deformed Hermitean matrix model and the q-deformed matrix models associated to 3d N $$ \mathcal{N} $$ = 2 supersymmetric gauge theories on D 2 × q S 1 and S b ...

Phases in WLZZ matrix models

Physics Letters B
We discuss the space of solutions to the Ward identities associated with the WLZZ models. We mostly concentrate on the case of these models described by a two-matrix model with the cubic potential in one of the matrices.

The formal demography of kinship V: Kin loss, bereavement, and causes of death [PDF]

Demographic Research, 2023
BACKGROUND: The loss of kin by death has medical, psychological, and social effects on other members of a kinship network. Recent formal demographic models can account for deaths of kin, but not causes of those deaths.

Anyone Can Get Old—All You Have to Do Is Live Long Enough: Understanding Mortality and Life Expectancy in European Hedgehogs (Erinaceus europaeus)

Animals, 2023
The European hedgehog is in decline, triggering a need to monitor population dynamics to optimise conservation initiatives directed at this species.

The formal demography of kinship IV: Two-sex models and their approximations

Demographic Research, 2022
Background: Previous kinship models analyze female kin through female lines of descent, neglecting male kin and male lines of descent. Because males and females differ in mortality and fertility, including both sexes in kinship models is an important ...

Celestial Matrix Model

Physical Review Letters, 2022
We construct a Hermitian random matrix model that provides a stable non-perturbative completion of Cangemi-Jackiw (CJ) gravity, a two-dimensional theory of flat spacetimes. The matrix model reproduces, to all orders in the topological expansion, the Euclidean partition function of CJ gravity with an arbitrary number of boundaries.

The Anderson Model as a matrix model [PDF]

Nuclear Physics B - Proceedings Supplements, 1997
In this paper we describe a strategy to study the Anderson model of an electron in a random potential at weak coupling by a renormalization group analysis. There is an interesting technical analogy between this problem and the theory of random matrices.
