Information-Geometric Optimization on Spheres
Researchers have developed two information-geometric optimization (IGO) flows designed for black-box optimization problems on spheres. These methods utilize natural search gradients derived from the hyperbolic geometry of Poincaré and Bergman balls. The study demonstrates how ensembles of generalized Kuramoto oscillators on spheres can compute these natural search gradients and implement IGO algorithms, also noting a connection between natural gradient policies in Bergman balls and quantum decision-making.
