AI Ethics

Comprehensive AI ethics skill covering bias detection, fairness assessment, responsible AI development, and regulatory compliance.

When to Use This Skill

• Evaluating AI models for bias
• Implementing fairness measures
• Conducting ethical impact assessments
• Ensuring regulatory compliance (EU AI Act, etc.)
• Designing human-in-the-loop systems
• Creating AI transparency documentation
• Developing AI governance frameworks

Ethical Principles

Core AI Ethics Principles

Stakeholder Considerations

• Users: How does this affect people using the system?
• Subjects: How does this affect people the AI makes decisions about?
• Society: What are broader societal implications?
• Environment: What is the environmental impact?

Bias Detection & Mitigation

Types of AI Bias

Fairness Metrics

Group Fairness:

• Demographic Parity: Equal positive rates across groups
• Equalized Odds: Equal TPR and FPR across groups
• Predictive Parity: Equal precision across groups

Individual Fairness:

• Similar individuals should receive similar predictions
• Counterfactual fairness: Would outcome change if protected attribute differed?

Bias Mitigation Strategies

Pre-processing:

• Resampling/reweighting training data
• Removing biased features
• Data augmentation for underrepresented groups

In-processing:

• Fairness constraints in loss function
• Adversarial debiasing
• Fair representation learning

Post-processing:

• Threshold adjustment per group
• Calibration
• Reject option classification

Explainability & Transparency

Explanation Types

Explainability Techniques

• SHAP: Feature importance values
• LIME: Local interpretable explanations
• Attention maps: For neural networks
• Decision trees: Inherently interpretable
• Feature importance: Global model understanding

Model Cards

Document for each model:

• Model purpose and intended use
• Training data description
• Performance metrics by subgroup
• Limitations and ethical considerations
• Version and update history

AI Governance

AI Risk Assessment

Risk Categories (EU AI Act):

Governance Framework

1. Policy: Define ethical principles and boundaries
2. Process: Review and approval workflows
3. People: Roles and responsibilities (ethics board)
4. Technology: Tools for monitoring and enforcement

Documentation Requirements

• Data provenance and lineage
• Model training documentation
• Testing and validation results
• Deployment and monitoring plans
• Incident response procedures

Human Oversight

Human-in-the-Loop Patterns

Designing for Human Control

• Clear escalation paths
• Override capabilities
• Confidence thresholds for automation
• Audit trails
• Feedback mechanisms

Privacy Considerations

Data Minimization

• Collect only necessary data
• Anonymize when possible
• Aggregate rather than individual data
• Delete data when no longer needed

Privacy-Preserving Techniques

• Differential privacy
• Federated learning
• Secure multi-party computation
• Homomorphic encryption

Environmental Impact

Considerations

• Training compute requirements
• Inference energy consumption
• Hardware lifecycle
• Data center energy sources

Mitigation

• Efficient architectures
• Model distillation
• Transfer learning
• Green hosting providers
