torch-uncertainty 0.2.1

Uncertainty quantification library in PyTorch

TorchUncertainty is a package designed to help you leverage uncertainty quantification techniques and make your deep neural networks more reliable. It aims at being collaborative and including as many methods as possible, so reach out to add yours!

:construction: TorchUncertainty is in early development :construction: - expect changes, but reach out and contribute if you are interested in the project! Please raise an issue if you have any bugs or difficulties and join the discord server.

:books: Our webpage and documentation is available here: torch-uncertainty.github.io. :books:

TorchUncertainty contains the official implementations of multiple papers from major machine-learning and computer vision conferences and was/will be featured in tutorials at WACV 2024, HAICON 2024 and ECCV 2024.

---

This package provides a multi-level API, including:

• easy-to-use :zap: lightning uncertainty-aware training & evaluation routines for 4 tasks: classification, probabilistic and pointwise regression, and segmentation.
• ready-to-train baselines on research datasets, such as ImageNet and CIFAR
• pretrained weights for these baselines on ImageNet and CIFAR (:construction: work in progress :construction:).
• layers, models, metrics, & losses available for use in your networks
• scikit-learn style post-processing methods such as Temperature Scaling.

Have a look at the Reference page or the API reference for a more exhaustive list of the implemented methods, datasets, metrics, etc.

:gear: Installation

TorchUncertainty requires Python 3.10 or greater. Install the desired PyTorch version in your environment. Then, install the package from PyPI:

pip install torch-uncertainty

The installation procedure for contributors is different: have a look at the contribution page.
