The nonlocal attraction-repulsion transport equation with power kernels

Massimo Fornasier, Hui Huang, Lukang Sun

We study a nonlocal continuity equation on in which a probability density is driven by the competition between attraction toward a prescribed background measure …

Quantitative estimate of the overdamped limit for the Vlasov-Fokker-Planck systems

Hui Huang

This note adapts a probabilistic approach to establish a quantified estimate of the overdamped limit for the Vlasov-Fokker-Planck equation towards the aggregation-diffusion equatio…

Mean-field particle swarm optimization

Sara Grassi, Hui Huang, Lorenzo Pareschi +1

In this work we survey some recent results on the global minimization of a non-convex and possibly non-smooth high dimensional objective function by means of particle based gradien…

A Measure Theoretical Approach to the Mean-field Maximum Principle for Training NeurODEs

Benoît Bonnet, Cristina Cipriani, Massimo Fornasier +1

In this paper we consider a measure-theoretical formulation of the training of NeurODEs in the form of a mean-field optimal control with -regularization of the control. We der…

On the mean-field limit for the consensus-based optimization

Hui Huang, Jinniao Qiu

This paper is concerned with the large particle limit for the consensus-based optimization (CBO), which was postulated in the pioneering works [6,28]. In order to solve this open p…

Zero-Inertia Limit: from Particle Swarm Optimization to Consensus Based Optimization

Cristina Cipriani, Hui Huang, Jinniao Qiu

Recently a continuous description of the particle swarm optimization (PSO) based on a system of stochastic differential equations was proposed by Grassi and Pareschi in arXiv:2012.…

Anisotropic Diffusion in Consensus-based Optimization on the Sphere

Massimo Fornasier, Hui Huang, Lorenzo Pareschi +1

In this paper we are concerned with the global minimization of a possibly non-smooth and non-convex objective function constrained on the unit hypersphere by means of a multi-agent…

Consensus-Based Optimization on Hypersurfaces: Well-Posedness and Mean-Field Limit

Massimo Fornasier, Hui Huang, Lorenzo Pareschi +1

We introduce a new stochastic differential model for global optimization of nonconvex functions on compact hypersurfaces. The model is inspired by the stochastic Kuramoto-Vicsek sy…

The microscopic derivation and well-posedness of the stochastic Keller-Segel equation

Hui Huang, Jinniao Qiu

In this paper, we propose and study a stochastic aggregation-diffusion equation of the Keller-Segel (KS) type for modeling the chemotaxis in dimensions . Unlike the classica…

Zero-diffusion Limit for Aggregation Equations over Bounded Domains

Razvan C. Fetecau, Hui Huang, Daniel Messenger +1

We establish the zero-diffusion limit for both continuous and discrete aggregation models over convex and bounded domains. Compared with a similar zero-diffusion limit derived in […
