Tabular Imbalanced Regression Datasets

Repository Summary

This repository provides a collection of 81 tabular datasets curated for research on tabular imbalanced regression problems. They were obtained from the various studies carried out on the subject (source and papers listed below). Its objective is to centralize datasets commonly used in the literature, serving as a solid reference point for future work.

Additional datasets can be contributed or requested — feel free to open an issue or pull request.

Citation

If you use dataset from this repository in your research, please cite our paper: Samuel Stocksieker, Denys Pommeret. A Comprehensive Survey on Imbalanced Regression: Definitions, Solutions, and Future Directions. 2025. ⟨hal-05213741⟩ https://hal.science/hal-05213741

Dataset Structure

This collection is intended for training, evaluating, and benchmarking models in imbalanced regression tasks. All datasets have been preprocessed to consistently place the target variable as the first column. A detailed summary of the 81 datasets is available in the table below. A second table lists the datasets used by each referenced paper in the survey. This metadata enables standardized comparisons and better understanding of dataset difficulty and imbalance characteristics.

Python Utilities

This repository includes Python code to compute imbalance coefficient based on the target distribution. The script imbalance_coefficient.py provides the function imb_coef() for both continuous and discrete targets.

You can explore our Python implementation and a usage notebook in the imbalance_coefficient/ subfolder:

—imbalance_metric.py: Python function to compute the imbalance ratio.
—Demo Notebook: notebook demonstration.

Dataset Overview

For each dataset, the following metadata is provided:

—n_obs: Number of observations
—p_var: Total number of features
—p_num: Number of numerical features
—p_cat: Number of categorical features
—Type: Type of target variable (continuous, integer, etc.)
—Skew: Skewness of the target distribution
—Imb. Coef.: Imbalance coefficient as defined in Section \ref{imbCoef}
—mIR: Mean Imbalanced Ratio, as introduced by Wibbeke et al., 2025
—Miss.: Proportion of missing values
—Used: Number of times the dataset has been used in published papers
