⚖️ Lab Mission: Build Ethical AI Framework

Prevent $200M in discrimination lawsuits in 90 minutes

⏱️ Time Remaining: 90:00
Complete all tasks to achieve compliance!
⚠️ CRITICAL ALERT: TechGlobal's AI systems are under federal investigation. You have 90 minutes to implement comprehensive bias detection and mitigation before regulatory shutdown. The company's survival depends on your code.

🔍 Task 1: Discover the Discrimination 10 points

Load TechGlobal's hiring data and identify patterns of discrimination. This dataset contains 50,000 job applications with concerning bias patterns.

💡 Hint: Look for disparate impact ratios below 0.8 (the 80% rule). Key patterns to identify:
  • Gender: Female candidates hired at 27% vs Male at 73%
  • Race: Significant disparities across ethnic groups
  • Age: Discrimination against 40+ candidates
Calculate: min(selection_rate) / max(selection_rate) for each attribute

⚖️ Task 2: Build Comprehensive Bias Detector 15 points

Create a bias detection system that implements multiple fairness metrics required for legal compliance.

💡 Hint: Remember the key fairness metrics: 
# Demographic Parity: P(Ŷ=1|A=a) = P(Ŷ=1|A=b)
rates = [pred[feature==g].mean() for g in groups]
dp_diff = max(rates) - min(rates)

# Disparate Impact: min/max selection rate ratio
di_ratio = min(rates) / max(rates) if max(rates) > 0 else 1

# Equalized Odds: Equal TPR and FPR across groups
tn, fp, fn, tp = confusion_matrix(y_true, y_pred).ravel()
tpr = tp / (tp + fn)
fpr = fp / (fp + tn)

🔧 Task 3: Pre-processing - Fix the Data 20 points

Implement data reweighting to reduce historical bias before training. This is your first line of defense.

💡 Hint: Reweighting formula to achieve demographic parity:
  • For each (group, outcome) combination
  • Weight = P(group) × P(outcome) / P(group AND outcome)
  • This makes the weighted distribution fair
  • Expected to reduce bias by 40-60% with minimal accuracy loss

🎯 Task 4: In-processing - Fair Learning 20 points

Implement fairness constraints directly in the model training objective. This ensures the model learns fair patterns.

💡 Hint: Lagrangian optimization approach: 
# Combined objective function:
# L = accuracy_loss + λ × fairness_violation

# Grid search over λ ∈ [0, 1]
# λ = 0: Only optimize accuracy (biased)
# λ = 1: Only optimize fairness (random)
# λ = 0.3-0.5: Good balance

# Expected results:
# - 60-80% bias reduction
# - 3-5% accuracy cost
# - Achieves legal compliance

🎚️ Task 5: Post-processing - Optimize Thresholds 15 points

Implement group-specific decision thresholds to achieve equal opportunity. Different thresholds ensure fairness in outcomes.

💡 Hint: Threshold optimization strategy:
  • Different thresholds per group equalize opportunity
  • If Group A has lower scores, use lower threshold
  • Target: Same positive rate across all groups
  • Can achieve 70-90% bias reduction
  • Trade-off: Individuals with same score may get different outcomes

🔍 Task 6: Build Explainability System 15 points

Implement GDPR-compliant explanations for every AI decision. Required by law for automated decision-making.

💡 Hint: GDPR-compliant explanations must include:
  • Clear decision outcome and confidence
  • Main factors influencing the decision
  • Flag if protected attributes affected outcome
  • Provide recourse (what to change for different outcome)
  • Store explanations for audit trail

📊 Task 7: Deploy Continuous Monitoring 10 points

Implement real-time fairness monitoring to detect and prevent future bias before it causes legal issues.

💡 Hint: Monitoring best practices:
  • Check fairness metrics every batch/day/week
  • Set strict thresholds (DI > 0.8)
  • Escalate alerts based on severity
  • Auto-trigger retraining if drift detected
  • Maintain audit log for compliance

🚀 Task 8: Deploy Complete Ethical AI System 15 points

Integrate all components into a production-ready ethical AI pipeline that prevents discrimination and ensures compliance.

💡 Hint: Complete pipeline checklist:
  • ✓ Pre-processing: Data reweighting
  • ✓ In-processing: Fairness constraints
  • ✓ Post-processing: Threshold optimization
  • ✓ Explainability: GDPR compliance
  • ✓ Monitoring: Real-time bias detection
  • ✓ Documentation: Complete audit trail
