Are Three Matrices All You Need To Beat the Market? Observable Matrix Dynamics for Portfolio Optimization

Igor Halperin

We present a simple framework for dynamic portfolio management that uses nothing but daily prices, trading volumes, and market capitalizations. Its state is three fixed-size matric…

Observable Matrix Dynamics of Stocks

Igor Halperin

The Observable Matrix Dynamics (OMD) approach monitors the time development of complex non-linear systems through the trajectory of a fixed-size distance matrix and its spectrum. W…

Learning as Observable Matrix Dynamics: Diffusive Relaxations versus Phase Transitions

Igor Halperin

Observable Matrix Dynamics (OMD) is a diagnostic framework that probes the dynamics of high-dimensional internal representations of inputs by a neural network via a fixed-size $N \…

I-BBS: Coordinate-Free Inference of Latent Sub-Manifolds Using Random Distance Matrix Theory

Igor Halperin

Bogomolny, Bohigas and Schmit (BBS) found that the spectrum of the pairwise distance matrix on N points sampled from a smooth d-dimensional manifold encodes a signature of the unde…

Frustrated Dynamics of Distance Matrices

Igor Halperin

We introduce the Frustrated Distance Matrix (FDM) model, a dynamic extension of the static distance-matrix ensemble on S^2 analyzed by Bogomolny, Bohigas, and Schmit (BBS). Its ent…

Frustrated Fields: Statistical Field Theory for Frustrated Brownian Particles on 2D Manifolds

Igor Halperin

We develop a statistical field theory that describes the large-N limit of a system of Brownian particles with quenched random pairwise interactions on a compact two-dimensional Rie…

Order Out of Noise and Disorder: Fate of the Frustrated Manifold

Igor Halperin

We study Langevin dynamics of Brownian particles on two-dimensional Riemannian manifolds, interacting through pairwise potentials linear in geodesic distance with quenched rand…
