A Practical Approach to Novel Class Discovery in Tabular Data

2 code implementations9 Nov 2023 Colin Troisemaine, Alexandre Reiffers-Masson, Stéphane Gosselin, Vincent Lemaire, Sandrine Vaton

In particular, the number of novel classes is usually assumed to be known in advance, and their labels are sometimes used to tune hyperparameters.

Novel Class Discovery: an Introduction and Key Concepts

2 code implementations22 Feb 2023 Colin Troisemaine, Vincent Lemaire, Stéphane Gosselin, Alexandre Reiffers-Masson, Joachim Flocon-Cholet, Sandrine Vaton

We then give an overview of the different families of approaches, organized by the way they transfer knowledge from the labeled set to the unlabeled set.

Contrastive Learning Novel Class Discovery +1

Découvrir de nouvelles classes dans des données tabulaires

1 code implementation28 Nov 2022 Colin Troisemaine, Joachim Flocon-Cholet, Stéphane Gosselin, Sandrine Vaton, Alexandre Reiffers-Masson, Vincent Lemaire

In Novel Class Discovery (NCD), the goal is to find new classes in an unlabeled set given a labeled set of known but different classes.

Multi-Task Learning Novel Class Discovery

Generalized Stochastic Backpropagation

no code implementations1 Jan 2021 Amine Echraibi, Joachim Flocon Cholet, Stéphane Gosselin, Sandrine Vaton

Backpropagating gradients through random variables is at the heart of numerous machine learning applications.

On the Variational Posterior of Dirichlet Process Deep Latent Gaussian Mixture Models

no code implementations16 Jun 2020 Amine Echraibi, Joachim Flocon-Cholet, Stéphane Gosselin, Sandrine Vaton

Thanks to the reparameterization trick, deep latent Gaussian models have shown tremendous success recently in learning latent representations.

Large-Scale Characterization and Segmentation of Internet Path Delays with Infinite HMMs

1 code implementation28 Oct 2019 Maxime Mouchet, Sandrine Vaton, Thierry Chonavel, Emile Aben, Jasper den Hertog

In this article we introduce a new model, the HDP-HMM or infinite hidden Markov model, whose performance in trace segmentation is very close to human cognition.
