Towards Few-Annotation Learning in Computer Vision: Application to Image Classification and Object Detection tasks

no code implementations8 Nov 2023 Quentin Bouniot

In this thesis, we develop theoretical, algorithmic and experimental contributions for Machine Learning with limited labels, and more specifically for the tasks of Image Classification and Object Detection in Computer Vision.

Tailoring Mixup to Data for Calibration

2 code implementations2 Nov 2023 Quentin Bouniot, Pavlo Mozharovskyi, Florence d'Alché-Buc

In this work, we argue that the likelihood of manifold intrusion increases with the distance between data to mix.

Towards Few-Annotation Learning for Object Detection: Are Transformer-based Models More Efficient ?

1 code implementation30 Oct 2023 Quentin Bouniot, Angélique Loesch, Romaric Audigier, Amaury Habrard

For specialized and dense downstream tasks such as object detection, labeling data requires expertise and can be very expensive, making few-shot and semi-supervised models much more attractive alternatives.

Proposal-Contrastive Pretraining for Object Detection from Fewer Data

no code implementations25 Oct 2023 Quentin Bouniot, Romaric Audigier, Angélique Loesch, Amaury Habrard

However, for unsupervised pretraining, the popular contrastive learning requires a large batch size and, therefore, a lot of resources.

From Alexnet to Transformers: Measuring the Non-linearity of Deep Neural Networks with Affine Optimal Transport

1 code implementation17 Oct 2023 Quentin Bouniot, Ievgen Redko, Anton Mallasto, Charlotte Laclau, Karol Arndt, Oliver Struckmeier, Markus Heinonen, Ville Kyrki, Samuel Kaski

In the last decade, we have witnessed the introduction of several novel deep neural network (DNN) architectures exhibiting ever-increasing performance across diverse tasks.

Optimal Transport as a Defense Against Adversarial Attacks

1 code implementation5 Feb 2021 Quentin Bouniot, Romaric Audigier, Angélique Loesch

This leads to SAT (Sinkhorn Adversarial Training), a more robust defense against adversarial attacks.

Improving Few-Shot Learning through Multi-task Representation Learning Theory

1 code implementation5 Oct 2020 Quentin Bouniot, Ievgen Redko, Romaric Audigier, Angélique Loesch, Amaury Habrard

In this paper, we consider the framework of multi-task representation (MTR) learning where the goal is to use source tasks to learn a representation that reduces the sample complexity of solving a target task.

Putting Theory to Work: From Learning Bounds to Meta-Learning Algorithms

no code implementations28 Sep 2020 Quentin Bouniot, Ievgen Redko, Romaric Audigier, Angélique Loesch, Amaury Habrard

To the best of our knowledge, this is the first contribution that puts the most recent learning bounds of meta-learning theory into practice for the popular task of few-shot classification.
