Smooth Pseudo-Labeling

no code implementations23 May 2024 Nikolaos Karaliolios, Hervé Le Borgne, Florian Chabot

Semi-Supervised Learning (SSL) seeks to leverage large amounts of non-annotated data along with the smallest amount possible of annotated data in order to achieve the same level of performance as if all data were annotated.

TIAM -- A Metric for Evaluating Alignment in Text-to-Image Generation

1 code implementation11 Jul 2023 Paul Grimal, Hervé Le Borgne, Olivier Ferret, Julien Tourille

While several metrics have been proposed to assess the rendering of images, it is crucial for Text-to-Image (T2I) models, which generate images based on a prompt, to consider additional aspects such as to which extent the generated image matches the important content of the prompt.

Self-Improving SLAM in Dynamic Environments: Learning When to Mask

1 code implementation15 Oct 2022 Adrian Bojko, Romain Dupont, Mohamed Tamaazousti, Hervé Le Borgne

Thus, we propose a novel SLAM that learns when masking objects improves its performance in dynamic scenarios.

Learning Semantic Ambiguities for Zero-Shot Learning

1 code implementation5 Jan 2022 Celina Hanouti, Hervé Le Borgne

State of the art approaches rely on generative models that synthesize visual features from the prototype of a class, such that a classifier can then be learned in a supervised manner.

Multi-Attribute Balanced Sampling for Disentangled GAN Controls

1 code implementation28 Oct 2021 Perla Doubinsky, Nicolas Audebert, Michel Crucianu, Hervé Le Borgne

We propose to address disentanglement by subsampling the generated data to remove over-represented co-occuring attributes thus balancing the semantics of the dataset before training the classifiers.

Zero-shot Learning with Deep Neural Networks for Object Recognition

no code implementations5 Feb 2021 Yannick Le Cacheux, Hervé Le Borgne, Michel Crucianu

The general approach is to learn a mapping from visual data to semantic prototypes, then use it at inference to classify visual samples from the class prototypes only.

Using Sentences as Semantic Representations in Large Scale Zero-Shot Learning

no code implementations6 Oct 2020 Yannick Le Cacheux, Hervé Le Borgne, Michel Crucianu

Zero-shot learning aims to recognize instances of unseen classes, for which no visual instance is available during training, by learning multimodal relations between samples from seen classes and corresponding class semantic representations.
