Conformal Approach To Gaussian Process Surrogate Evaluation With Coverage Guarantees

1 code implementation15 Jan 2024 Edgar Jaber, Vincent Blot, Nicolas Brunel, Vincent Chabridon, Emmanuel Remy, Bertrand Iooss, Didier Lucor, Mathilde Mougeot, Alessandro Leite

Gaussian processes (GPs) are a Bayesian machine learning approach widely used to construct surrogate models for the uncertainty quantification of computer simulation codes in industrial applications.

Maximum Weight Entropy

2 code implementations27 Sep 2023 Antoine de Mathelin, François Deheeger, Mathilde Mougeot, Nicolas Vayatis

Under this paradigm, the epistemic uncertainty is described by the weight distribution of maximal entropy that produces neural networks "consistent" with the training observations.

Out-of-Distribution Detection Uncertainty Quantification

Deep Anti-Regularized Ensembles provide reliable out-of-distribution uncertainty quantification

no code implementations8 Apr 2023 Antoine de Mathelin, Francois Deheeger, Mathilde Mougeot, Nicolas Vayatis

We derive a simple and practical approach to produce such ensembles, based on an original anti-regularization term penalizing small weights and a control process of the weight increase which maintains the in-distribution loss under an acceptable threshold.

Fixed-budget online adaptive learning for physics-informed neural networks. Towards parameterized problem inference

2 code implementations22 Dec 2022 Thi Nguyen Khoa Nguyen, Thibault Dairay, Raphaël Meunier, Christophe Millet, Mathilde Mougeot

We show that FBOAL is able to identify the high-gradient locations and even give better predictions for some physical fields than the classical PINNs with collocation points sampled on a pre-adapted finite element mesh built thanks to numerical expert knowledge.

To tree or not to tree? Assessing the impact of smoothing the decision boundaries

no code implementations7 Oct 2022 Anthea Mérida, Argyris Kalogeratos, Mathilde Mougeot

The approach we propose starts with the rigid decision boundaries of a seed Decision Tree (seed DT), which is used to initialize a Neural DT (NDT).

A Binded VAE for Inorganic Material Generation

1 code implementation17 Dec 2021 Fouad Oubari, Antoine de Mathelin, Rodrigue Décatoire, Mathilde Mougeot

Designing new industrial materials with desired properties can be very expensive and time consuming.

ADAPT : Awesome Domain Adaptation Python Toolbox

1 code implementation7 Jul 2021 Antoine de Mathelin, Mounir Atiq, Guillaume Richard, Alejandro de la Concha, Mouad Yachouti, François Deheeger, Mathilde Mougeot, Nicolas Vayatis

In this paper, we introduce the ADAPT library, an open source Python API providing the implementation of the main transfer learning and domain adaptation methods.

Discrepancy-Based Active Learning for Domain Adaptation

2 code implementations ICLR 2022 Antoine de Mathelin, Francois Deheeger, Mathilde Mougeot, Nicolas Vayatis

The goal of the paper is to design active learning strategies which lead to domain adaptation under an assumption of Lipschitz functions.

Model family selection for classification using Neural Decision Trees

no code implementations20 Jun 2020 Anthea Mérida Montes de Oca, Argyris Kalogeratos, Mathilde Mougeot

In our approach, this is realized by progressively relaxing the decision boundaries of the initial decision trees (the RMs) as long as this is beneficial in terms of performance measured on an analyzed dataset.

Adversarial Weighting for Domain Adaptation in Regression

2 code implementations15 Jun 2020 Antoine de Mathelin, Guillaume Richard, Francois Deheeger, Mathilde Mougeot, Nicolas Vayatis

We present a novel instance-based approach to handle regression tasks in the context of supervised domain adaptation under an assumption of covariate shift.

Domain Adaptation regression

A clusterwise supervised learning procedure based on aggregation of distances

no code implementations20 Sep 2019 Aurélie Fisher, Mathilde Mougeot, Sothea Has

Nowadays, many machine learning procedures are available on the shelve and may be used easily to calibrate predictive models on supervised data.

Clustering

Aggregation using input-output trade-off

no code implementations8 Mar 2018 Aurélie Fischer, Mathilde Mougeot

We also show on simulated examples that this procedure mixing inputs and outputs is still robust to high dimensional inputs.
