Boarding for ISS: Imbalanced Self-Supervised: Discovery of a Scaled Autoencoder for Mixed Tabular Datasets

no code implementations23 Mar 2024 Samuel Stocksieker, Denys Pommeret, Arthur Charpentier

This paper aims to fill this gap by examining the specific challenges posed by data imbalance in self-supervised learning in the domain of tabular data, with a primary focus on autoencoders.

Generalized Oversampling for Learning from Imbalanced datasets and Associated Theory

no code implementations5 Aug 2023 Samuel Stocksieker, Denys Pommeret, Arthur Charpentier

In this paper, we propose a data augmentation procedure, the GOLIATH algorithm, based on kernel density estimates which can be used in classification and regression.

Data Augmentation for Imbalanced Regression

1 code implementation18 Feb 2023 Samuel Stocksieker, Denys Pommeret, Arthur Charpentier

In this work, we consider the problem of imbalanced data in a regression framework when the imbalanced phenomenon concerns continuous or discrete covariates.

Non-parametric Clustering of Multivariate Populations with Arbitrary Sizes

no code implementations11 Nov 2022 Yves Ismaël Ngounou Bakam, Denys Pommeret

It relies on the differences between orthogonal projection coefficients of the K density copulas estimated from the K populations.

Mixed data Deep Gaussian Mixture Model: A clustering model for mixed datasets

1 code implementation13 Oct 2020 Robin Fuchs, Denys Pommeret, Cinzia Viroli

In this work we introduce a multilayer architecture model-based clustering method called Mixed Deep Gaussian Mixture Model (MDGMM) that can be viewed as an automatic way to merge the clustering performed separately on continuous and non-continuous data.
