Transductive Learning for Textual Few-Shot Classification in API-based Embedding Models

no code implementations21 Oct 2023 Pierre Colombo, Victor Pellegrain, Malik Boudiaf, Victor Storchan, Myriam Tami, Ismail Ben Ayed, Celine Hudelot, Pablo Piantanida

First, we introduce a scenario where the embedding of a pre-trained model is served through a gated API with compute-cost and data-privacy constraints.

Causal Dynamic Variational Autoencoder for Counterfactual Regression in Longitudinal Data

no code implementations16 Oct 2023 Mouad El Bouchattaoui, Myriam Tami, Benoit Lepetit, Paul-Henry Cournède

Under unconfoundedness, we target the Individual Treatment Effect (ITE) estimation with unobserved heterogeneity in the treatment response due to missing risk factors.

Open-Set Likelihood Maximization for Few-Shot Learning

1 code implementation CVPR 2023 Malik Boudiaf, Etienne Bennequin, Myriam Tami, Antoine Toubhans, Pablo Piantanida, Céline Hudelot, Ismail Ben Ayed

We tackle the Few-Shot Open-Set Recognition (FSOSR) problem, i. e. classifying instances among a set of classes for which we only have a few labeled samples, while simultaneously detecting instances that do not belong to any known class.

Model-Agnostic Few-Shot Open-Set Recognition

1 code implementation18 Jun 2022 Malik Boudiaf, Etienne Bennequin, Myriam Tami, Celine Hudelot, Antoine Toubhans, Pablo Piantanida, Ismail Ben Ayed

Through extensive experiments spanning 5 datasets, we show that OSTIM surpasses both inductive and existing transductive methods in detecting open-set instances while competing with the strongest transductive methods in classifying closed-set instances.

Bridging Few-Shot Learning and Adaptation: New Challenges of Support-Query Shift

1 code implementation25 May 2021 Etienne Bennequin, Victor Bouvier, Myriam Tami, Antoine Toubhans, Céline Hudelot

To classify query instances from novel classes encountered at test-time, they only require a support set composed of a few labelled samples.

Spatial Contrastive Learning for Few-Shot Classification

1 code implementation26 Dec 2020 Yassine Ouali, Céline Hudelot, Myriam Tami

In this paper, we explore contrastive learning for few-shot classification, in which we propose to use it as an additional auxiliary training objective acting as a data-dependent regularizer to promote more general and transferable features.

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.

Smooth And Consistent Probabilistic Regression Trees

no code implementations NeurIPS 2020 Sami Alkhoury, Emilie Devijver, Marianne Clausel, Myriam Tami, Eric Gaussier, Georges Oppenheim

We propose here a generalization of regression trees, referred to as Probabilistic Regression (PR) trees, that adapt to the smoothness of the prediction function relating input and output variables while preserving the interpretability of the prediction and being robust to noise.

Autoregressive Unsupervised Image Segmentation

1 code implementation ECCV 2020 Yassine Ouali, Céline Hudelot, Myriam Tami

In this work, we propose a new unsupervised image segmentation approach based on mutual information maximization between different constructed views of the inputs.

Target Consistency for Domain Adaptation: when Robustness meets Transferability

no code implementations25 Jun 2020 Yassine Ouali, Victor Bouvier, Myriam Tami, Céline Hudelot

Learning Invariant Representations has been successfully applied for reconciling a source and a target domain for Unsupervised Domain Adaptation.

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.

An Overview of Deep Semi-Supervised Learning

1 code implementation9 Jun 2020 Yassine Ouali, Céline Hudelot, Myriam Tami

Deep neural networks demonstrated their ability to provide remarkable performances on a wide range of supervised learning tasks (e. g., image classification) when trained on extensive collections of labeled data (e. g., ImageNet).

Semi-Supervised Semantic Segmentation with Cross-Consistency Training

5 code implementations CVPR 2020 Yassine Ouali, Céline Hudelot, Myriam Tami

To leverage the unlabeled examples, we enforce a consistency between the main decoder predictions and those of the auxiliary decoders, taking as inputs different perturbed versions of the encoder's output, and consequently, improving the encoder's representations.

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.
