Ensemble-based gradient inference for particle methods in optimization and sampling

1 code implementation23 Sep 2022 Claudia Schillings, Claudia Totzeck, Philipp Wacker

We propose an approach based on function evaluations and Bayesian inference to extract higher-order differential information of objective functions {from a given ensemble of particles}.

Optimal control for interacting particle systems driven by neural networks

no code implementations29 Jan 2021 Simone Göttlich, Claudia Totzeck

We propose a neural network approach to model general interaction dynamics and an adjoint based stochastic gradient descent algorithm to calibrate its parameters.

An analytical framework for a consensus-based global optimization method

1 code implementation31 Jan 2016 José A. Carrillo, Young-Pil Choi, Claudia Totzeck, Oliver Tse

This work justifies the optimization algorithm in the mean-field sense showing the convergence to the global minimizer for a large class of functions.
