Autor: Pierre Jacob, Espen Bernton, Mathieu Gerber, Christian P. Robert

Publikováno v: Bernton, E, Jacob, P E, Gerber, M & Robert, C P 2019, ' On parameter estimation with the Wasserstein distance ', Information and Inference: A Journal of the IMA . https://doi.org/10.1093/imaiai/iaz003

Statistical inference can be performed by minimizing, over the parameter space, the Wasserstein distance between model distributions and the empirical distribution of the data. We study asymptotic properties of such minimum Wasserstein distance estim

A growing number of generative statistical models do not permit the numerical evaluation of their likelihood functions. Approximate Bayesian computation (ABC) has become a popular approach to overcome this issue, in which one simulates synthetic data

Coupled circuit and magnetic fast model for high‐speed permanent‐magnet drive design

Autor: Adrien Gilson, Christophe Espanet, Mathieu Gerber, Frédéric Dubas

Publikováno v: IET Electrical Systems in Transportation. 8:27-34

High-speed electrical actuators used in harsh environments for automotive applications have surged in recent years. Examples comprise electrically assisted turbochargers, air compressors for fuel-cells, and waste heat recovery generators. In those ki

Stability with respect to initial conditions in V-norm for nonlinear filters with ergodic observations

Autor: Nick Whiteley, Mathieu Gerber

Publikováno v: Gerber, M & Whiteley, N 2017, ' Stability with respect to initial conditions in V-norm for nonlinear filters with ergodic observations ', Journal of Applied Probability, vol. 54, no. 1, pp. 118-133 . https://doi.org/10.1017/jpr.2016.90

We establish conditions for an exponential rate of forgetting of the initial distribution of nonlinear filters in $V$-norm, path-wise along almost all observation sequences. In contrast to previous works, our results allow for unbounded test function

Impacts of Using Wide Bandgap Transistors on Electronics and Motors

Autor: Mathieu Gerber, Noureddine Takorabet, Farid Meibody-Tabar

Publikováno v: 2019 19th International Symposium on Electromagnetic Fields in Mechatronics, Electrical and Electronic Engineering (ISEF).

In this paper, the impacts of wide-bandgap transistors on electronic and motor designs are studied. From magnetic and electric models, the high frequency parasitics for both electronics and motor are determinated. Then, high frequency circuit models

Online Inference with Multi-modal Likelihood Functions

Autor: Mathieu Gerber, Kari Heine

Let $(Y_t)_{t\geq 1}$ be a sequence of i.i.d.\ observations and $\{f_\theta,\theta\in \mathbb{R}^d\}$ be a parametric model. We introduce a new online algorithm for computing a sequence $(\hat{\theta}_t)_{t\geq 1}$ which is shown to converge almost s
