Stochastic Adversarial Gradient Embedding for Active Domain Adaptation

no code implementations3 Dec 2020 Victor Bouvier, Philippe Very, Clément Chastagnol, Myriam Tami, Céline Hudelot

First, we select for annotation target samples that are likely to improve the representations' transferability by measuring the variation, before and after annotation, of the transferability loss gradient.

Robust Domain Adaptation: Representations, Weights and Inductive Bias

no code implementations24 Jun 2020 Victor Bouvier, Philippe Very, Clément Chastagnol, Myriam Tami, Céline Hudelot

The emergence of Domain Invariant Representations (IR) has improved drastically the transferability of representations from a labelled source domain to a new and unlabelled target domain.

Domain-Invariant Representations: A Look on Compression and Weights

no code implementations25 Sep 2019 Victor Bouvier, Céline Hudelot, Clément Chastagnol, Philippe Very, Myriam Tami

Second, we show that learning weighted representations plays a key role in relaxing the constraint of invariance and then preserving the risk of compression.

Learning Invariant Representations for Sentiment Analysis: The Missing Material is Datasets

no code implementations29 Jul 2019 Victor Bouvier, Philippe Very, Céline Hudelot, Clément Chastagnol

Learning representations which remain invariant to a nuisance factor has a great interest in Domain Adaptation, Transfer Learning, and Fair Machine Learning.

Hidden Covariate Shift: A Minimal Assumption For Domain Adaptation

no code implementations29 Jul 2019 Victor Bouvier, Philippe Very, Céline Hudelot, Clément Chastagnol

Such approach consists in learning a representation of the data such that the label distribution conditioned on this representation is domain invariant.
