Out-of-Distribution (OOD) Detection with Deep Neural Networks based on PyTorch.
The library provides:
- Out-of-Distribution Detection Methods
- Loss Functions
- Datasets
- Neural Network Architectures as well as pretrained weights
- Useful Utilities
and is designed such that it should be compatible with frameworks
like `pytorch-lightning <https://www.pytorchlightning.ai>`_ and
`pytorch-segmentation-models <https://github.com/qubvel/segmentation_models.pytorch>`_.
The library also covers some methods from closely related fields such as Open-Set Recognition, Novelty Detection,
Confidence Estimation and Anomaly Detection.
📚 Documentation
^^^^^^^^^^^^^^^^^^^
The documentation is available `here <https://pytorch-ood.readthedocs.io/en/latest/>`_.
**NOTE**: An important convention adopted in ``pytorch-ood`` is that **OOD detectors predict outlier scores**
that should be larger for outliers than for inliers.
If you notice that the scores predicted by a detector do not match the formulas in the corresponding publication,
it may be possible that we multiplied the scores by negative one to comply with this convention.
⏳ Quick Start
^^^^^^^^^^^^^^^^^
Load model pre-trained on CIFAR-10 with the Energy-Bounded Learning Loss [#EnergyBasedOOD]_, and predict on some dataset ``data_loader`` using
Energy-based Out-of-Distribution Detection [#EnergyBasedOOD]_, calculating the common OOD detection metrics:
.. code-block:: python
from pytorch_ood.model import WideResNet
from pytorch_ood.detector import EnergyBased
from pytorch_ood.utils import OODMetrics
# Create Neural Network
model = WideResNet(num_classes=10, pretrained="er-cifar10-tune").eval().cuda()
# Create detector
detector = EnergyBased(model)
# Evaluate
metrics = OODMetrics()
for x, y in data_loader:
metrics.update(detector(x.cuda()), y)
print(metrics.compute())
You can find more examples in the `documentation <https://pytorch-ood.readthedocs.io/en/latest/auto_examples/benchmarks/>`_.
🛠 ️️Installation
