Disentangled Deep Smoothed Bootstrap for Fair Imbalanced Regression

2025-08-19 · Samuel Stocksieker, Denys pommeret, Arthur Charpentier arxiv

Imbalanced distribution learning is a common and significant challenge in predictive modeling, often reducing the performance of standard algorithms. Although various approaches address this issue, most are tailored to classification problems, with a limited focus on regression. This paper introduces a novel method to improve learning on tabular data within the Imbalanced Regression (IR) framework, which is a critical problem. We propose using Variational Autoencoders (VAEs) to model and define a latent representation of data distributions. However, VAEs can be inefficient with imbalanced data like other standard approaches. To address this, we develop an innovative data generation method that combines a disentangled VAE with a Smoothed Bootstrap applied in the latent space. We evaluate the efficiency of this method through numerical comparisons with competitors on benchmark datasets for IR.

Equity-Directed Bootstrapping: Examples and Analysis

2021-08-14 · Harish S. Bhat, Majerle E. Reeves, Sidra Goldman-Mellor

When faced with severely imbalanced binary classification problems, we often train models on bootstrapped data in which the number of instances of each class occur in a more favorable ratio, e.g., one. We view algorithmi…
