Deep Insight And Neural Network Analysis

DIANNA is a Python package that brings explainable AI (XAI) to your research project. It wraps carefully selected XAI methods in a simple, uniform interface. It's built by, with and for (academic) researchers and research software engineers working on machine learning projects.

Why DIANNA?

DIANNA software is addressing needs of both (X)AI reseachers and mostly the various domains scientists who are using or will use AI models for their research without being experts in (X)AI. DIANNA is future-proof: the only XAI library supporting the Open Neural Network Exchange (ONNX) format.

• Provides an easy-to-use interface for non (X)AI experts
• Implements well-known XAI methods (LIME, RISE and Kernal SHAP) chosen by systematic and objective evaluation criteria
• Supports the de-facto standard format for neural network models - ONNX.
• Includes clear instructions for export/conversions from Tensorflow, Pytorch, Keras and skikit-learn to ONNX.
• Supports both images and text data modalities. Time series, tabular data and even embeddings support is planned.
• Comes with simple intuitive image and text benchmarks
• Easily extendable to other XAI methods

For more information on the unique stengths of DIANNA with comparision to other tools, please see the context landscape.

Installation

DIANNA can be installed from PyPI using pip on any of the supported Python versions (see badge):

python3 -m pip install dianna

To install the most recent development version directly from the GitHub repository run:

python3 -m pip install git+https://github.com/dianna-ai/dianna.git

Pre-requisites only for Macbook Pro with M1 Pro chip users

• To install TensorFlow you can follow this tutorial.

• To install TensorFlow Addons you can follow these steps. For further reading see this issue. Note that this temporary solution works only for macOS versions >= 12.0.

• Before installing DIANNA, comment tensorflow requirement in setup.cfg file (tensorflow package for M1 is called tensorflow-macos).

How to use DIANNA

To use DIANNA you need a trained AI model (in ONNX format) and a data item (e.g. an image or text, etc.) for which you would like to explain the output of the model. DIANNA calls an explainable AI method to produce the relevance scores of each data pont (e.g. pixel, word) to a given model's decision overlaid on the data item.

For example usage see the DIANNA tutorials. For creating or converting a trained model to ONNX see the ONNX models and for example datasets- the Datasets sections below.

Datasets

DIANNA comes with simple datasets. Their main goal is to provide intuitive insight into the working of the XAI methods. They can be used as benchmarks for evaluation and comparison of existing and new XAI methods.

Images

Dataset	Description	Examples	Generation
Binary MNIST	Greyscale images of the digits "1" and "0" - a 2-class subset from the famous MNIST dataset for handwritten digit classification.		Binary MNIST dataset generation
Simple Geometric (circles and triangles)	Images of circles and triangles for 2-class geometric shape classificaiton. The shapes of varying size and orientation and the background have varying uniform gray levels.		Simple geometric shapes dataset generation
Simple Scientific (LeafSnap30)	Color images of tree leaves - a 30-class post-processed subset from the LeafSnap dataset for automatic identification of North American tree species.		LeafSnap30 dataset generation

Text

Dataset	Description	Examples	Generation
Stanford sentiment treebank	Dataset for predicting the sentiment, positive or negative, of movie reviews.	This movie was actually neither that funny, nor super witty.	Sentiment treebank

ONNX models

We work with ONNX! ONNX is a great unified neural network standard which can be used to boost reproducible science. Using ONNX for your model also gives you a boost in performance! In case your models are still in another popular DNN (deep neural network) format, here are some simple recipes to convert them:

• pytorch - use the built-in torch.onnx.export function to convert pytorch models to onnx.
• tensorflow - use the tf2onnx package to convert tensorflow models to onnx.
• keras - same as the conversion from tensorflow to onnx, the tf2onnx package also supports keras.
• scikit-learn - use the skl2onnx package to scikit-learn models to onnx.

More converters with examples and tutorials can be found on the ONNX tutorial page.

And here are links to notebooks showing how we created our models on the benchmark datasets:

We envision the birth of the ONNX Scientific models zoo soon...

Tutorials

DIANNA supports different data modalities and XAI methods. The table contains links to the relevant XAI method's papers. There are DIANNA tutorials covering each supported method and data modality on a least one dataset. Our future plans to expand DIANNA with more data modalities and XAI methods are given in the ROADMAP.

LRP and PatternAttribution also feature in the top 5 of our thoroughly evaluated XAI methods using objective critera (details in coming blog-post). Contributing by adding these and more (new) post-hoc explainability methods on ONNX models is very welcome!
