Throughout your journey of preparing for DP-100: Designing and Implementing a Data Science Solution on Azure, you’ll encounter a major concept in model assessment dubbed “Responsible AI”. This post will dive deep into precisely what Responsible AI entails and how to assess your model by adhering to its guidelines in the context of Azure.
A. Understanding Responsible AI
Responsible AI revolves around designing and implementing models and systems in a manner that respects fundamental ethical principles, legal stipulations, transparency norms and safeguards against harmful outcomes. It is a holistic approach that Microsoft strongly advocates for, and it is depicted through six principles: Fairness, Reliability and safety, Privacy and security, Transparency, Accountability, and Inclusiveness.
B. Assessing a Model with Responsible AI Guidelines
When assessing a machine-learning model with the principles of Responsible AI, it’s essential to follow a structured, thorough process.
- Transparency: Start by providing an explanation for each step in your modeling process. With Azure, model interpretability can be achieved using Azure Machine Learning’s interpretability package. This enables you to provide clarity on your model’s behaviour and the predictions that it makes.
from interpret.ext.blackbox import TabularExplainer
# 'features' and 'classes' fields are optional
tab_explainer = TabularExplainer(model,
X_train,
features=feature_names,
classes=target_names)
- Accountability: Microsoft’s Azure allows you to track data experiments, versions, metrics and outputs round the clock, making it easy to assess how, why, when and by whom a model was created or altered.
from azureml.core.run import Run
run.log('Accuracy', accuracy)
run.log_list('Accuracy_list', run_history)
# Save the trained model
os.makedirs('./outputs/model', exist_ok=True)
joblib.dump(value=model, filename='./outputs/model.pkl')
- Fairness: Ensuring your model doesn’t suffer from bias by treating all categories of people fairly is crucial. Microsoft developed the Fairlearn toolkit, which can be utilized to assess model fairness and mitigate any observed unfairness issues.
In Fairlearn, the MetricFrame class is commonly used to generate fairness metrics comparison across different groups.
from fairlearn.metrics import MetricFrame
group_metrics = MetricFrame(metrics={'precision':precision_score,
'recall': recall_score,
'false_positive_rate': false_positive_rate},
y_true=y_true,
y_pred=y_pred,
sensitive_features=sensitive_features)
- Privacy and Security: One of the vital principles of the Responsible AI, Azure provides various data privacy and security features. Sensitive information can be anonymized using the Differential Privacy technique. Moreover, it offers features like network isolation, encryption, access controls and audit logs for data security.
- Reliability and Safety: Model testing and validation are fundamental to achieving model reliability. Microsoft provides Azure Data Factory (ADF) to create automated and scalable data pipelines for model testing.
- Inclusiveness: It’s important to ensure that the model delivers high performance for everyone it impacts. This means considering demographic, socio-economic and geographic diversity. Azure Machine Learning Studio allows users to test models with varying datasets to ensure inclusiveness.
In conclusion, Microsoft Azure offers a multitude of tools and functionalities to implement Responsible AI effectively. As you progress in your DP-100 certification journey, understanding how to assess a model using these guidelines becomes crucial for your success and the integration of future AI models in an ethical, secure, fair, and accountable manner.
