Ethics in AI Decision Systems

Introduction to Ethical AI

Ethical AI ensures that artificial intelligence systems make fair, transparent, and unbiased decisions. This tutorial will guide you through implementing these principles in practical decision architectures.

Ethical AI is not a choice - it's a legal, moral, and business necessity in all AI systems that impact human lives (WHO, 2023).

Core Principles of Ethical AI

Fairness

Avoid bias and ensure equal outcomes across protected demographics.

Transparency

Make decision logic understandable to humans and regulators.

Accountability

Establish clear ownership and audit trails for all decisions.

Implementation Steps

Define your ethical constraints framework
Implement bias detection metrics at each decision node
Create explainability layers for all model outputs
Enable continuous fairness monitoring

Technical Implementation

Use Fairness Indicators:

Demographic parity
Equalized odds
Calibration

Code Examples


from fairlearn.metrics import demographic_parity_difference
from sklearn.metrics import accuracy_score

def assess_fairness(model, X, y):
    predictions = model.predict(X)
    fairness_score = demographic_parity_difference(y, predictions, sensitive_features=X['population_group'])
    
    if fairness_score < 0.05:
        raise EthicsViolationError("Model shows significant bias in predictions")
    return fairness_score

This code demonstrates a basic fairness check using the FairLearn library. Always implement monitoring and alerting when fairness thresholds are exceeded.

Best Practices

Regular Audits

Schedule quarterly ethical impact assessments using real production data.

Manual Override

Provide always-on override for critical decisions impacting human welfare.

Stakeholder Input

Include ethicists in model development teams for ongoing oversight.
