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

Principle Description

Fairness AI should not discriminate against individuals or groups

Transparency AI decisions should be explainable

Privacy Personal data must be protected

Accountability Clear responsibility for AI outcomes

Safety AI should not cause harm

Human Agency Humans should maintain control

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

Bias Type Source Example

Historical Training data reflects past discrimination Hiring models favoring male candidates

Representation Underrepresented groups in training data Face recognition failing on darker skin

Measurement Proxy variables for protected attributes ZIP code correlating with race

Aggregation One model for diverse populations Medical model trained only on one ethnicity

Evaluation Biased evaluation metrics Accuracy hiding disparate impact

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

Type Audience Purpose

Global Developers Understand overall model behavior

Local End users Explain specific decisions

Counterfactual Affected parties What would need to change for different outcome

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):

Risk Level Examples Requirements

Unacceptable Social scoring, manipulation Prohibited

High Healthcare, employment, credit Strict requirements

Limited Chatbots Transparency obligations

Minimal Spam filters No requirements

Governance Framework

• Policy: Define ethical principles and boundaries

• Process: Review and approval workflows

• People: Roles and responsibilities (ethics board)

• 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

Pattern Use Case Example

Human-in-the-Loop High-stakes decisions Medical diagnosis confirmation

Human-on-the-Loop Monitoring with intervention Content moderation escalation

Human-out-of-Loop Low-risk, high-volume Spam filtering

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
