<b>Deep Imbalanced Regression (DIR)</b> aims to learn from imbalanced data with continuous targets, <br> tackle potential missing data for certain regions, and generalize to the entire target range.
</p>


## Beyond Imbalanced Classification: Brief Introduction for DIR
Existing techniques for learning from imbalanced data focus on targets with __categorical__ indices, i.e., the targets are different classes. However, many real-world tasks involve __continuous__ and even infinite target values. We systematically investigate _Deep Imbalanced Regression (DIR)_, which aims to learn continuous targets from natural imbalanced data, deal with potential missing data for certain target values, and generalize to the entire target range.

We curate and benchmark large-scale DIR datasets for common real-world tasks in _computer vision_, _natural language processing_, and _healthcare_ domains, ranging from single-value prediction such as age, text similarity score, health condition score, to dense-value prediction such as depth.


## Usage
We separate the codebase for different datasets into different subfolders. Please go into the subfolders for more information (e.g., installation, dataset preparation, training, evaluation & models).
