AI Explainability 360 (v0.3.0)

The AI Explainability 360 toolkit is an open-source library that supports interpretability and explainability of datasets and machine learning models. The AI Explainability 360 Python package includes a comprehensive set of algorithms that cover different dimensions of explanations along with proxy explainability metrics. The AI Explainability 360 toolkit supports tabular, text, images, and time series data.

The AI Explainability 360 interactive experience provides a gentle introduction to the concepts and capabilities by walking through an example use case for different consumer personas. The tutorials and example notebooks offer a deeper, data scientist-oriented introduction. The complete API is also available.

There is no single approach to explainability that works best. There are many ways to explain: data vs. model, directly interpretable vs. post hoc explanation, local vs. global, etc. It may therefore be confusing to figure out which algorithms are most appropriate for a given use case. To help, we have created some guidance material and a taxonomy tree that can be consulted.

We have developed the package with extensibility in mind. This library is still in development. We encourage you to contribute your explainability algorithms, metrics, and use cases. To get started as a contributor, please join the AI Explainability 360 Community on Slack by requesting an invitation here. Please review the instructions to contribute code and python notebooks here.

(Optional) Create a virtual environment

AI Explainability 360 requires specific versions of many Python packages which may conflict with other projects on your system. A virtual environment manager is strongly recommended to ensure dependencies may be installed safely. If you have trouble installing the toolkit, try this first.

Conda

Conda is recommended for all configurations though Virtualenv is generally interchangeable for our purposes. Miniconda is sufficient (see the difference between Anaconda and Miniconda if you are curious) and can be installed from here if you do not already have it.

Then, create a new python environment based on the explainability algorithms you wish to use by referring to the table above. For example, for python 3.10, use the following command:

conda create --name aix360 python=3.10
conda activate aix360

The shell should now look like (aix360) $. To deactivate the environment, run:

(aix360)$ conda deactivate

The prompt will return back to $ or (base)$.

Note: Older versions of conda may use source activate aix360 and source deactivate (activate aix360 and deactivate on Windows).

Installation

Clone the latest version of this repository:

(aix360)$ git clone https://github.com/Trusted-AI/AIX360

If you'd like to run the examples and tutorial notebooks, download the datasets now and place them in their respective folders as described in aix360/data/README.md.

Then, navigate to the root directory of the project which contains setup.py file and run:

(aix360)$ pip install -e .[<algo1>,<algo2>, ...]

The above command installs packages required by specific algorithms. Here <algo> refers to the installation keyword in table above. For instance to install packages needed by BRCG, DIPVAE, and TSICE algorithms, one could use

(aix360)$ pip install -e .[rbm,dipvae,tsice]

The default command pip install . installs default dependencies alone.

Note that you may not be able to install two algorithms that require different versions of python in the same environment (for instance contrastive along with rbm).

If you face any issues, please try upgrading pip and setuptools and uninstall any previous versions of aix360 before attempting the above step again.

(aix360)$ pip install --upgrade pip setuptools
(aix360)$ pip uninstall aix360

PIP Installation of AI Explainability 360

If you would like to quickly start using the AI explainability 360 toolkit without explicitly cloning this repository, you can use one of these options:

Install v0.3.0 via repository link

(your environment)$ pip install -e git+https://github.com/Trusted-AI/AIX360.git#egg=aix360[<algo1>,<algo2>,...]

For example, use pip install -e git+https://github.com/Trusted-AI/AIX360.git#egg=aix360[rbm,dipvae,tsice] to install BRCG, DIPVAE, and TSICE. You may need to install cmake if its not already installed in your environment using conda install cmake.

Install v0.3.0 (or previous versions) via pypi

(your environment)$ pip install aix360

If you follow either of these two options, you will need to download the notebooks available in the examples folder separately.

Dealing with installation errors

AI Explainability 360 toolkit is tested on Windows, MacOS, and Linux. However, if you still face installation issues due to package dependencies, please try installing the corresponding package via conda (e.g. conda install package-name) and then install the toolkit by following the usual steps. For example, if you face issues related to pygraphviz during installation, use conda install pygraphviz and then install the toolkit.

Please use the right python environment based on the table above.

Running in Docker

Under AIX360 directory build the container image from Dockerfile using docker build -t aix360_docker .
Start the container image using command docker run -it -p 8888:8888 aix360_docker:latest bash assuming port 8888 is free on your machine.
Inside the container start jupuyter lab using command jupyter lab --allow-root --ip 0.0.0.0 --port 8888 --no-browser
Access the sample tutorials on your machine using URL localhost:8888
