[Alibi Detect](https://github.com/SeldonIO/alibi-detect) is a Python library focused on **outlier**, **adversarial** and **drift** detection. The package aims to cover both online and offline detectors for tabular data, text, images and time series. Both **TensorFlow** and **PyTorch** backends are supported for drift detection.

*  [Documentation](https://docs.seldon.io/projects/alibi-detect/en/stable/)

For more background on the importance of monitoring outliers and distributions in a production setting, check out [this talk](https://slideslive.com/38931758/monitoring-and-explainability-of-models-in-production?ref=speaker-37384-latest) from the *Challenges in Deploying and Monitoring Machine Learning Systems* ICML 2020 workshop, based on the paper [Monitoring and explainability of models in production](https://arxiv.org/abs/2007.06299) and referencing Alibi Detect.

For a thorough introduction to drift detection, check out [Protecting Your Machine Learning Against Drift: An Introduction](https://youtu.be/tL5sEaQha5o). The talk covers what drift is and why it pays to detect it, the different types of drift, how it can be detected in a principled manner and also describes the anatomy of a drift detector.

## Installation and Usage

The package, `alibi-detect` can be installed from:

- PyPI or GitHub source (with `pip`)

- Anaconda (with `conda`/`mamba`)

### With pip

- alibi-detect can be installed from [PyPI](https://pypi.org/project/alibi-detect):

   ```bash

   pip install alibi-detect

   ```

   

- Alternatively, the development version can be installed:

   ```bash

   pip install git+https://github.com/SeldonIO/alibi-detect.git

   ```

- To install with the TensorFlow backend:

  ```bash

  pip install alibi-detect[tensorflow]

  ```

- To install with the PyTorch backend:

  ```bash

  pip install alibi-detect[torch]

  ```

- To install with the KeOps backend:

  ```bash

  pip install alibi-detect[keops]

  ```

- To use the `Prophet` time series outlier detector:

   ```bash

   pip install alibi-detect[prophet]

   ```

### With conda

To install from [conda-forge](https://conda-forge.org/) it is recommended to use [mamba](https://mamba.readthedocs.io/en/stable/), 

which can be installed to the *base* conda enviroment with:

```bash

conda install mamba -n base -c conda-forge

```

To install alibi-detect:

```bash

mamba install -c conda-forge alibi-detect

```

### Usage

We will use the [VAE outlier detector](https://docs.seldon.io/projects/alibi-detect/en/stable/od/methods/vae.html) to illustrate the API.

```python

from alibi_detect.od import OutlierVAE

from alibi_detect.saving import save_detector, load_detector

# initialize and fit detector

od = OutlierVAE(threshold=0.1, encoder_net=encoder_net, decoder_net=decoder_net, latent_dim=1024)

od.fit(x_train)

# make predictions

preds = od.predict(x_test)

# save and load detectors

filepath = './my_detector/'

save_detector(od, filepath)

od = load_detector(filepath)

```

The predictions are returned in a dictionary with as keys `meta` and `data`. `meta` contains the detector's metadata while `data` is in itself a dictionary with the actual predictions. It contains the outlier, adversarial or drift scores and thresholds as well as the predictions whether instances are e.g. outliers or not. The exact details can vary slightly from method to method, so we encourage the reader to become familiar with the [types of algorithms supported](https://docs.seldon.io/projects/alibi-detect/en/stable/overview/algorithms.html).

## Supported Algorithms

The following tables show the advised use cases for each algorithm. The column *Feature Level* indicates whether the detection can be done at the feature level, e.g. per pixel for an image. Check the [algorithm reference list](#reference-list) for more information with links to the documentation and original papers as well as examples for each of the detectors.

#### TensorFlow and PyTorch support

The drift detectors support TensorFlow, PyTorch and (where applicable) [KeOps](https://www.kernel-operations.io/keops/index.html) backends. 

However, Alibi Detect does not install these by default. See the [installation options](#installation-and-usage) for more details.

```python

from alibi_detect.cd import MMDDrift

cd = MMDDrift(x_ref, backend='tensorflow', p_val=.05)

preds = cd.predict(x)

```

The same detector in PyTorch:

```python

cd = MMDDrift(x_ref, backend='pytorch', p_val=.05)

preds = cd.predict(x)

```

Or in KeOps:

```python

cd = MMDDrift(x_ref, backend='keops', p_val=.05)

preds = cd.predict(x)

```

#### Built-in preprocessing steps

Alibi Detect also comes with various preprocessing steps such as randomly initialized encoders, pretrained text

embeddings to detect drift on using the [transformers](https://github.com/huggingface/transformers) library and 

extraction of hidden layers from machine learning models. This allows to detect different types of drift such as 

**covariate and predicted distribution shift**. The preprocessing steps are again supported in TensorFlow and PyTorch.

```python

from alibi_detect.cd.tensorflow import HiddenOutput, preprocess_drift

model = # TensorFlow model; tf.keras.Model or tf.keras.Sequential

preprocess_fn = partial(preprocess_drift, model=HiddenOutput(model, layer=-1), batch_size=128)

cd = MMDDrift(x_ref, backend='tensorflow', p_val=.05, preprocess_fn=preprocess_fn)

preds = cd.predict(x)

```

Check the example notebooks (e.g. [CIFAR10](https://docs.seldon.io/projects/alibi-detect/en/stable/examples/cd_mmd_cifar10.html), [movie reviews](https://docs.seldon.io/projects/alibi-detect/en/stable/examples/cd_text_imdb.html)) for more details.

## Datasets

The package also contains functionality in `alibi_detect.datasets` to easily fetch a number of datasets for different modalities. For each dataset either the data and labels or a *Bunch* object with the data, labels and optional metadata are returned. Example:

```python

from alibi_detect.datasets import fetch_ecg

(X_train, y_train), (X_test, y_test) = fetch_ecg(return_X_y=True)

```

### Sequential Data and Time Series

- **Genome Dataset**: `fetch_genome`

  - Bacteria genomics dataset for out-of-distribution detection, released as part of [Likelihood Ratios for Out-of-Distribution Detection](https://arxiv.org/abs/1906.02845). From the original *TL;DR*: *The dataset contains genomic sequences of 250 base pairs from 10 in-distribution bacteria classes for training, 60 OOD bacteria classes for validation, and another 60 different OOD bacteria classes for test*. There are respectively 1, 7 and again 7 million sequences in the training, validation and test sets. For detailed info on the dataset check the [README](https://storage.cloud.google.com/seldon-datasets/genome/readme.docx?organizationId=156002945562).

  

  ```python

  from alibi_detect.datasets import fetch_genome

  

  (X_train, y_train), (X_val, y_val), (X_test, y_test) = fetch_genome(return_X_y=True)

  ```

- **ECG 5000**: `fetch_ecg`

  - 5000 ECG's, originally obtained from [Physionet](https://archive.physionet.org/cgi-bin/atm/ATM).

- **NAB**: `fetch_nab`

  - Any univariate time series in a DataFrame from the [Numenta Anomaly Benchmark](https://github.com/numenta/NAB). A list with the available time series can be retrieved using `alibi_detect.datasets.get_list_nab()`.

### Images

- **CIFAR-10-C**: `fetch_cifar10c`

  - CIFAR-10-C ([Hendrycks & Dietterich, 2019](https://arxiv.org/abs/1903.12261)) contains the test set of CIFAR-10, but corrupted and perturbed by various types of noise, blur, brightness etc. at different levels of severity, leading to a gradual decline in a classification model's performance trained on CIFAR-10. `fetch_cifar10c` allows you to pick any severity level or corruption type. The list with available corruption types can be retrieved with `alibi_detect.datasets.corruption_types_cifar10c()`. The dataset can be used in research on robustness and drift. The original data can be found [here](https://zenodo.org/record/2535967#.XnAM2nX7RNw). Example:

  

  ```python

  from alibi_detect.datasets import fetch_cifar10c

  

  corruption = ['gaussian_noise', 'motion_blur', 'brightness', 'pixelate']

  X, y = fetch_cifar10c(corruption=corruption, severity=5, return_X_y=True)

  ```

  

- **Adversarial CIFAR-10**: `fetch_attack`

  - Load adversarial instances on a ResNet-56 classifier trained on CIFAR-10. Available attacks: [Carlini-Wagner](https://arxiv.org/abs/1608.04644) ('cw') and [SLIDE](https://arxiv.org/abs/1904.13000) ('slide'). Example:

  

  ```python

  from alibi_detect.datasets import fetch_attack

  

  (X_train, y_train), (X_test, y_test) = fetch_attack('cifar10', 'resnet56', 'cw', return_X_y=True)

  ```

### Tabular

- **KDD Cup '99**: `fetch_kdd`

  - Dataset with different types of computer network intrusions. `fetch_kdd` allows you to select a subset of network intrusions as targets or pick only specified features. The original data can be found [here](http://kdd.ics.uci.edu/databases/kddcup99/kddcup99.html).

## Models

Models and/or building blocks that can be useful outside of outlier, adversarial or drift detection can be found under `alibi_detect.models`. Main implementations:

- [PixelCNN++](https://arxiv.org/abs/1701.05517): `alibi_detect.models.pixelcnn.PixelCNN`

- Variational Autoencoder: `alibi_detect.models.autoencoder.VAE`

- Sequence-to-sequence model: `alibi_detect.models.autoencoder.Seq2Seq`

- ResNet: `alibi_detect.models.resnet`

  - Pre-trained ResNet-20/32/44 models on CIFAR-10 can be found on our [Google Cloud Bucket](https://console.cloud.google.com/storage/browser/seldon-models/alibi-detect/classifier/cifar10/?organizationId=156002945562&project=seldon-pub) and can be fetched as follows:

  ```python

  from alibi_detect.utils.fetching import fetch_tf_model

  

  model = fetch_tf_model('cifar10', 'resnet32')

  ```

## Integrations

Alibi-detect is integrated in the machine learning model deployment platform [Seldon Core](https://docs.seldon.io/projects/seldon-core/en/stable/index.html) and model serving framework [KFServing](https://github.com/kubeflow/kfserving).

- **Seldon Core**: [outlier](https://docs.seldon.io/projects/seldon-core/en/stable/analytics/outlier_detection.html) and [drift](https://docs.seldon.io/projects/seldon-core/en/stable/analytics/drift_detection.html) detection worked examples.

- **KFServing**: [outlier](https://github.com/kubeflow/kfserving/tree/master/docs/samples/outlier-detection/alibi-detect/cifar10) and [drift](https://github.com/kubeflow/kfserving/tree/master/docs/samples/drift-detection/alibi-detect/cifar10) detection examples.
