Tabular Performance Enhancements

AutoGluon 1.0 features major enhancements to predictive quality, establishing a new state-of-the-art in Tabular modeling. To the best of our knowledge, AutoGluon 1.0 marks the largest leap forward in the state-of-the-art for tabular data since the original AutoGluon paper from March 2020. The enhancements come primarily from two features: Dynamic stacking to mitigate stacked overfitting, and a new learned model hyperparameters portfolio via Zeroshot-HPO, obtained from the newly released TabRepo ensemble simulation library. Together, they lead to a 75% win-rate compared to AutoGluon 0.8 with faster inference speed, lower disk usage, and higher stability.

AutoML Benchmark Results

OpenML released the official 2023 AutoML Benchmark results on November 16th, 2023. Their results show AutoGluon 0.8 as the state-of-the-art in AutoML systems across a wide variety of tasks: “Overall, in terms of model performance, AutoGluon consistently has the highest average rank in our benchmark.” We now showcase that AutoGluon 1.0 achieves far superior results even to AutoGluon 0.8!

Below is a comparison on the OpenML AutoML Benchmark across 1040 tasks. LightGBM, XGBoost, and CatBoost results were obtained via AutoGluon, and other methods are from the official AutoML Benchmark 2023 results. AutoGluon 1.0 has a 95%+ win-rate against traditional tabular models, including a 99% win-rate vs LightGBM and a 100% win-rate vs XGBoost. AutoGluon 1.0 has between an 82% and 94% win-rate against other AutoML systems. For all methods, AutoGluon is able to achieve >10% average loss improvement (Ex: Going from 90% accuracy to 91% accuracy is a 10% loss improvement). AutoGluon 1.0 achieves first place in 63% of tasks, with lightautoml having the second most at 12% (AutoGluon 0.8 previously took first place 48% of the time). AutoGluon 1.0 even achieves a 7.4% average loss improvement over AutoGluon 0.8!

Method	AG Winrate	AG Loss Improvement	Rescaled Loss	Rank	Champion
AutoGluon 1.0 (Best, 4h8c)	-	-	0.04	1.95	63%
lightautoml (2023, 4h8c)	84%	12.0%	0.2	4.78	12%
H2OAutoML (2023, 4h8c)	94%	10.8%	0.17	4.98	1%
FLAML (2023, 4h8c)	86%	16.7%	0.23	5.29	5%
MLJAR (2023, 4h8c)	82%	23.0%	0.33	5.53	6%
autosklearn (2023, 4h8c)	91%	12.5%	0.22	6.07	4%
GAMA (2023, 4h8c)	86%	15.4%	0.28	6.13	5%
CatBoost (2023, 4h8c)	95%	18.2%	0.28	6.89	3%
TPOT (2023, 4h8c)	91%	23.1%	0.4	8.15	1%
LightGBM (2023, 4h8c)	99%	23.6%	0.4	8.95	0%
XGBoost (2023, 4h8c)	100%	24.1%	0.43	9.5	0%
RandomForest (2023, 4h8c)	97%	25.1%	0.53	9.78	1%

Not only is AutoGluon more accurate in 1.0, it is also more stable thanks to our new usage of Ray subprocesses during low-memory training, resulting in 0 task failures on the AutoML Benchmark.

AutoGluon 1.0 is capable of achieving the fastest inference throughput of any AutoML system while still obtaining state-of-the-art results. By specifying the infer_limit fit argument, users can trade off between accuracy and inference speed to meet their needs.

As seen in the below plot, AutoGluon 1.0 sets the Pareto Frontier for quality and inference throughput, achieving Pareto Dominance compared to all other AutoML systems. AutoGluon 1.0 High achieves superior performance to AutoGluon 0.8 Best with 8x faster inference and 8x less disk usage!

You can get more details on the results here.

We are excited to see what our users can accomplish with AutoGluon 1.0’s enhanced performance. As always, we will continue to improve AutoGluon in future releases to push the boundaries of AutoML forward for all.

AutoGluon Multimodal (AutoMM) Highlights in One Figure

AutoMM Uniqueness

AutoGluon Multimodal (AutoMM) distinguishes itself from other open-source AutoML toolboxes like AutosSklearn, LightAutoML, H2OAutoML, FLAML, MLJAR, TPOT and GAMA, which mainly focus on tabular data for classification or regression. AutoMM is designed for fine-tuning foundation models across multiple modalities—image, text, tabular, and document, either individually or combined. It offers extensive capabilities for tasks like classification, regression, object detection, named entity recognition, semantic matching, and image segmentation. In contrast, other AutoML systems generally have limited support for image or text, typically using a few pretrained models like EfficientNet or hand-crafted rules like bag-of-words as feature extractors. They often rely on traditional models or simple neural networks. AutoMM provides a uniquely comprehensive and versatile approach to AutoML, being the only AutoML system to support flexible multimodality and support for a wide range of tasks. A comparative table detailing support for various data modalities, tasks, and model types is provided below.

Papers

AutoGluon-TimeSeries: AutoML for Probabilistic Time Series Forecasting

We have published a paper on AutoGluon-TimeSeries at AutoML Conference 2023 (Paper Link, YouTube Video). In the paper, we benchmarked AutoGluon and popular open-source forecasting frameworks (including DeepAR, TFT, AutoARIMA, AutoETS, AutoPyTorch). AutoGluon produces SOTA results in point and probabilistic forecasting, and even achieves 65% win rate against the best-in-hindsight combination of models.

TabRepo: A Large Scale Repository of Tabular Model Evaluations and its AutoML Applications

We have published a paper on Tabular Zeroshot-HPO ensembling simulation to arXiv (Paper Link, GitHub). This paper is key to achieving the performance improvements seen in AutoGluon 1.0, and we plan to continue to develop the code-base to support future enhancements.

XTab: Cross-table Pretraining for Tabular Transformers

We have published a paper on tabular Transformer pre-training at ICML 2023 (Paper Link, GitHub). In the paper we demonstrate state-of-the-art performance for tabular deep learning models, including being able to match the performance of XGBoost and LightGBM models. While the pre-trained transformer is not yet incorporated into AutoGluon, we plan to integrate it in a future release.

Learning Multimodal Data Augmentation in Feature Space

Our paper on learning multimodal data augmentation was accepted at ICLR 2023 (Paper Link, GitHub). This paper introduces a plug-and-play module to learn multimodal data augmentation in feature space, with no constraints on the identities of the modalities or the relationship between modalities. We show that it can (1) improve the performance of multimodal deep learning architectures, (2) apply to combinations of modalities that have not been previously considered, and (3) achieve state-of-the-art results on a wide range of applications comprised of image, text, and tabular data. This work is not yet incorporated into AutoGluon, but we plan to integrate it in a future release.

Data Augmentation for Object Detection via Controllable Diffusion Models

Our paper on generative object detection data augmentation has been accepted at WACV 2024 (Paper and GitHub link will be available soon). This paper proposes a data augmentation pipeline based on controllable diffusion models and CLIP, with visual prior generation to guide the generation and post-filtering by category-calibrated CLIP scores to control its quality. We demonstrate that the performance improves across various tasks and settings when using our augmentation pipeline with different detectors. Although diffusion models are currently not integrated into AutoGluon, we plan to incorporate the data augmentation techniques in a future release.

Adapting Image Foundation Models for Video Understanding

We have published a paper on how to efficiently adapt image foundation models for video understanding at ICLR 2023 (Paper Link, GitHub). This paper introduces spatial adaptation, temporal adaptation and joint adaptation to gradually equip a frozen image model with spatiotemporal reasoning capability. The proposed method achieves competitive or even better performance than traditional full finetuning while largely saving the training cost of large foundation models.

Changes

Highlights

• AutoGluon TimeSeries introduced several major improvements, including new models, upgraded presets that lead to better forecast accuracy, and optimizations that speed up training & inference.

• AutoGluon Tabular now supports calibrating the decision threshold in binary classification (API), leading to massive improvements in metrics such as f1 and balanced_accuracy. It is not uncommon to see f1 scores improve from 0.70 to 0.73 as an example. We strongly encourage all users who are using these metrics to try out the new decision threshold calibration logic.

• AutoGluon MultiModal introduces two new features: 1) PDF document classification, and 2) Open Vocabulary Object Detection.

• AutoGluon MultiModal upgraded the presets for object detection, now offering medium_quality, high_quality, and best_quality options. The empirical results demonstrate significant ~20% relative improvements in the mAP (mean Average Precision) metric, using the same preset.

• AutoGluon Tabular has added an experimental Zeroshot HPO config which performs well on small datasets <10000 rows when at least an hour of training time is provided (~60% win-rate vs best_quality). To try it out, specify presets="experimental_zeroshot_hpo_hybrid" when calling fit().

• AutoGluon EDA added support for Anomaly Detection and Partial Dependence Plots.

• AutoGluon Tabular has added experimental support for TabPFN, a pre-trained tabular transformer model. Try it out via pip install autogluon.tabular[all,tabpfn] (hyperparameter key is “TABPFN”)!

Exploratory Data Analysis (EDA) tools

In 0.8 we introduce a few new tools to help with data exploration and feature engineering:

• Anomaly Detection @gradientsky (#3124, #3137) - helps to identify unusual patterns or behaviors in data that deviate significantly from the norm. It’s best used when finding outliers, rare events, or suspicious activities that could indicate fraud, defects, or system failures. Check the Anomaly Detection Tutorial to explore the functionality.

• Partial Dependence Plots @gradientsky (#3071, #3079) - visualize the relationship between a feature and the model’s output for each individual instance in the dataset. Two-way variant can visualize potential interactions between any two features. Please see this tutorial for more detail: Using Interaction Charts To Learn Information About the Data

Bug Fixes / Code and Doc Improvements

• Switch regression analysis in quick_fit to use residuals plot @gradientsky (#3039)
