Azure Machine Learning Responsible AI Dashboard

Welcome to the public preview for the new Responsible AI dashboard in Azure Machine Learning (AzureML) SDK/CLIv2 and studio. The following is a guide for you to onboard to the new capabilities. For questions, please contact mithigpe@microsoft.com. Visit the Microsoft how-to docs relating to this repo.

What is the new Responsible AI Dashboard?

Responsible AI is an approach to assessing, developing, and deploying AI systems in a safe, trustworthy, and ethical manner, and take responsible decisions and actions.

AzureML currently supports both model explanations and model fairness in public preview. As we expand our offerings of Responsible AI tools for AzureML users, the new Responsible AI Dashboard acts as a single pane of glass, bringing together several pre-existing features and brand new offerings under a one-stop-shop SDK package and studio UI dashboard:

  • Error Analysis (new) powered by Error Analysis: identify cohorts of data with higher error rate than the overall benchmark. These discrepancies might occur when the system or model underperforms for specific demographic groups or infrequently observed input conditions in the training data.

  • Data Explorer: explore your dataset by feature sets and other metrics such as predicted Y or true Y

  • Model Statistics: explore the distribution of your model outcomes and performance metrics

  • Model Interpretability powered by InterpretML, which explains blackbox models, helping users understand their model's global behavior, or the reasons behind individual predictions.

  • Counterfactual Analysis (new) powered by DiCE: explore feature-perturbed versions of the same datapoint that would have received a different prediction outcome, e.g., Taylor's loan has been rejected by the model. But they would have received the loan if their income was higher by $10,000.

  • Causal Analysis (new) powered by EconML, which focuses on answering What If-style questions to apply data-driven decision-making – how would revenue be affected if a corporation pursues a new pricing strategy? Would a new medication improve a patient’s condition, all else equal?

The dashboard offers users a new powerful and robust toolkit for understanding your model and data in order to develop your machine learning models responsibly, now all in one place and integrated with your AzureML workspace. With this dashboard, you can identify model errors, diagnose why those errors are happening, and mitigate them. Moreover, the causal decision-making capabilities provide actionable insights to your stakeholders and customers.

Please note: This initial version of the Responsible AI dashboard currently does not support the integration of fairness metrics. For fairness metrics, please refer to our existing offering here.

Supported scenarios, models and datasets

The AzureML components in this repo support computation of Responsible AI insights for scikit-learn models that are trained on pandas.DataFrame. The components accept both models and SciKit-Learn pipelines as input as long as the model or pipeline implements predict and predict_proba functions that conforms to the scikit-learn convention. If not compatible, you can wrap your model's prediction function into a wrapper class that transforms the output into the format that is supported (predict and predict_proba of scikit-learn), and pass that wrapper class to modules in this repo.

Currently, we support datasets having numerical and categorical features. The following table provides the scenarios supported for each of the four responsible AI insights:-

RAI insight Binary classification Multi-class classification Multilabel classification Regression Timeseries forecasting Categorical features Text features Image Features Recommender Systems Reinforcement Learning
Explainability Yes Yes No Yes No Yes No No No No
Error Analysis Yes Yes No Yes No Yes No No No No
Causal Analysis Yes No No Yes No Yes (max 5 features due to computational cost) No No No No
Counterfactual Yes Yes No Yes No Yes No No No No

This is all available via Python SDK or CLI.

Set Up

In this section, we will go over the basic setup steps that you need in order to generate Responsible AI insights for your models from SDK v2, CLI v2 and visualize the generated Responsible AI insights in AML studio.

Install Miniconda

Our setup script assumes that conda is installed and configured for your shell. Download and install MiniConda (External link). After installation, restart your shell, and make sure that you can run conda commands.

Create an AzureML workspace

Create an AzureML workspace by using the configuration notebook

Install the Azure CLI

Install the Azure CLI by following the instructions on the Microsoft docs site.

Clone this repository

If you have not already done so, clone this repository, and move into the root directory:

git clone https://github.com/Azure/RAI-vNext-Preview.git
cd RAI-vNext-Preview

Log in to Azure

Run the following to make sure you are logged in to Azure:

az login

Run the setup script

We provide a setup script which:

  • Creates a new conda environment
  • Installs all the required Python packages
  • Registers all the RAI components in your AzureML workspace
  • Sets the defaults for the az CLI to point to your workspace

To run the script in powershell, from the repository root, run:

 .\Quick-Setup.ps1

alternatively, an equivalent script for bash:

./quick-setup.bash <CONDA-ENV-NAME> <SUBSCRIPTION-ID> <RESOURCE-GROUP-NAME> <WORKSPACE-NAME>

This script will echo the supplied arguments and then pause briefly before continuing.

Generating Responsible AI Dashboard insights

Once you have created an Azure workspace and registered your components in the one-time setup above, you can create a Responsible AI dashboard via the CLI or SDK. Here are some useful examples to walk through to better understand how the dashboard works:

Responsible Decision Making Examples:

For examples using the CLI to generate the dashboard, check the examples/CLI folder

Viewing your Responsible AI Dashboard in the AzureML studio portal

After generating the Responsible AI insights, you can view them in your associated workspace in AzureML studio, under your model registry.

01

  1. Go to your model registry in your AzureML studio workspace
  2. Click on the model for which you've uploaded your Responsible AI insights

02 3. Click on the tab for Responsible AI dashboard (preview) under your model details page

03 4. Under the Responsible AI dashboard (preview) tab of your model details, you will see a list of your uploaded Responsible AI insights. You can upload more than one Responsible AI dashboard for each model. Each row represents one dashboard, with information on which components were uploaded to each dashboard (i.e. explanations, counterfactuals, etc).

04 5. At anytime while viewing the dashboard, if you wish to return to the model details page, click on Back to model details

  1. You can view the dashboard insights for each component filtered down on a cohort you specify (or view all the data with the global cohort). Hovering over the cohort name will show the number of datapoints and filters in that cohort as a tooltip.
  2. Switch which cohort you are applying to the dashboard.
  3. Create a new cohort based on filters you can apply in a flyout panel.
  4. View a list of all cohorts created and duplicate, edit or delete them.
  5. View a list of all Responsible AI components you've uploaded to this dashboard as well as hiding components. The layout of the dashboard will reflect the order of the components in this list.

Please note: Error Analysis, if generated, will always be at the top of the component list in your dashboard. Selecting on the nodes of the error tree or tiles of the error heatmap will automatically generate a temporary cohort that will be populated in the components below so that you can easily experiment with looking at insights for different areas of your error distribution.

05 6. In between each component you can add components by clicking the blue circular button with a plus sign. This will pop up a tooltip that will give you an option of adding whichever Responsible AI component you enabled with your SDK.

Accessing full functionality with a connected compute resource in Azure ML studio

Integrated compute instance must be attached to the Responsible AI dashboard to enable full functionality: Error analysis

  • Setting your global data cohort to any cohort of interest will update the error tree instead of disabling it.
  • Selecting other error or performance metrics is supported.
  • Selecting any subset of features for training the error tree map is supported.
  • Changing the minimum number of samples required per leaf node and error tree depth is supported.
  • Dynamically updating the heatmap for up to two features is supported. Feature importances
  • An individual conditional expectation (ICE) plot in the individual feature importance tab is supported. Counterfactual analysis
  • Generating a new what-if counterfactual datapoint to understand the minimum change required for a desired outcome is supported. Causal analysis
  • Selecting any individual datapoint, perturbing its treatment features, and seeing the expected causal outcome of causal what-if is supported (only for regression ML scenarios).

If the Responsible AI dashboard is created and viewed in a Jupyter notebook with a Python backend, it will be fully featured when running in that notebook.

Limitations

The current set of components have a number of limitations on their use:

  • All models must be in registered in AzureML in MLFlow format with an sklearn flavour
  • The models must be loadable in the component environment
  • The models must be pickleable
  • The models must be supplied to the RAI components using the 'Fetch Registered Model' component which we provide. We plan to switch to the new AzureML 'model-as-input' feature in the near future
  • The dataset inputs must be pandas DataFrames in Parquet format. We plan to start using AzureML's new MLTable feature in the near future
  • A model must still be supplied even if only a causal analysis of the data is performed. The DummyClassifier and DummyRegressor estimators from SciKit-Learn can be used for this purpose
