Understanding Machine Learning for Diversified Portfolio Construction by Explainable AI
In this paper, we construct a pipeline to investigate heuristic diversification strategies in asset allocation. We use machine learning …
Explainable AI in credit risk management
The paper proposes an explainable AI model that can be used in credit risk management and, in particular, in measuring the risks that …
Parameters Estimation for the Cosmic Microwave Background with Bayesian Neural Networks
In this paper, we present the first study that compares different models of Bayesian Neural Networks (BNNs) to predict the posterior …
Thermodynamics of Quantum Phase Transitions of a Dirac Oscillator in a Homogenous Magnetic Field
The Dirac oscillator in a homogenous magnetic field exhibits a chirality phase transition at a particular (critical) value of the …
Synthetic Generation of Local Minima and Saddle Points for Neural Networks
In this work-in-progress paper, we study the landscape of the empirical loss function of a feed-forward neural network, from the …
Spin-Coupling Diagrams and Incidence Geometry: A Note on Combinatorial and Quantum-Computational Aspects
This paper continues previous work on quantum mechanical angular momentum theory and its applications. Relationships with projective …
A Practical Look at Regge Calculus
Regge calculus is the classical starting point for a bunch of different models of quantum gravity. Moreover, it is often considered a …
The Screen representation of spin networks: 2D recurrence, eigenvalue equation for 6j symbols, geometric interpretation and Hamiltonian dynamics
This paper treats 6j symbols or their orthonormal forms as a function of two variables spanning a square manifold which we call the …
Single and Collective Dynamics of Discretized Geometries
This paper reports a summary of the results of the PhD thesis. It is divided into two parts. In the first part the dynamics of the …
Symmetric coupling of angular momenta, quadratic algebras and discrete polynomials
Eigenvalues and eigenfunctions of the volume operator, associated with the symmetric coupling of three SU(2) angular momentum …
Symmetric angular momentum coupling, the quantum volume operator and the 7-spin network: a computational perspective
A unified vision of the symmetric coupling of angular momenta and of the quantum mechanical volume operator is illustrated. The focus …
Hamiltonian dynamics of a quantum of space: hidden symmetries and spectrum of the volume operator, and discrete orthogonal polynomials
The action of the quantum mechanical volume operator, introduced in connection with a symmetric representation of the three-body …
