TabArena is a living benchmarking system that makes benchmarking tabular machine learning models a reliable experience. TabArena implements best practices to ensure methods are represented at their peak potential, including cross-validated ensembles, strong hyperparameter search spaces contributed by the method authors, early stopping, model refitting, parallel bagging, memory usage estimation, and more.

TabArena currently consists of:

• 51 manually curated tabular datasets representing real-world tabular data tasks.
• 9 to 30 evaluated splits per dataset.
• 16 tabular machine learning methods, including 3 tabular foundation models.
• 25,000,000 trained models across the benchmark, with all validation and test predictions cached to enable tuning and post-hoc ensembling analysis.
• A live TabArena leaderboard showcasing the results.

Please refer to our example scripts for using TabArena.

Please refer to our dataset curation repository to learn more about or contributed data!

To locally reproduce individual configurations and compare with the TabArena results of those configurations, refer to examples/tabarena/run_quickstart_tabarena.py.

To locally reproduce all tables and figures in the paper using the raw results data, run examples/tabarena/run_tabarena_eval.py

TabArena code is currently being polished. Documentation for TabArena will be available soon.

To install TabArena, ensure you are using Python 3.9-3.11. Then, run the following:

git clone https://github.com/autogluon/tabrepo.git
pip install -e tabrepo/[benchmark]
