Long-time Stability and Convergence of Particle Swarm Optimization

Giacomo Borghi, Hui Huang, Dohyeon Kim

Particle Swarm Optimization (PSO) is a global optimization algorithm defined by an interacting set of particles evolving over the search space. Heuristically motivated, its theoret…

Variational inference via Gaussian interacting particles in the Bures-Wasserstein geometry

Giacomo Borghi, José A. Carrillo

Motivated by variational inference methods, we propose a zeroth-order algorithm for solving optimization problems in the space of Gaussian probability measures. The algorithm is ba…

Two-Time-Scale Learning Dynamics: A Population View of Neural Network Training

Giacomo Borghi, Hyesung Im, Lorenzo Pareschi

Population-based learning paradigms, including evolutionary strategies, Population-Based Training (PBT), and recent model-merging methods, combine fast within-model optimisation wi…

Chaos propagation in genetic algorithms: An optimal transport approach

Giacomo Borghi

Genetic algorithms are high-level heuristic optimization methods which enjoy great popularity thanks to their intuitive description, flexibility, and, of course, effectiveness. The…

Swarm-based optimization with jumps: a kinetic BGK framework and convergence analysis

Giacomo Borghi, Hyesung Im, Lorenzo Pareschi

Metaheuristic algorithms are powerful tools for global optimization, particularly for non-convex and non-differentiable problems where exact methods are often impractical. Particle…

Wasserstein convergence rates for stochastic particle approximation of Boltzmann models

Giacomo Borghi, Lorenzo Pareschi

We establish quantitative convergence rates for stochastic particle approximation based on Nanbu-type Monte Carlo schemes applied to a broad class of collisional kinetic models. Us…
