Uncover hidden biases in data and models, then learn systematic approaches to address them.
Bias in AI systems can manifest in multiple forms: historical bias from training data, representation bias from sampling, measurement bias from proxy variables, and algorithmic bias from model architecture choices.
# Example: Detecting demographic parity
from aif360.metrics import BinaryLabelDatasetMetric
metric = BinaryLabelDatasetMetric(
dataset,
unprivileged_groups=[{'gender': 0}],
privileged_groups=[{'gender': 1}]
)
print(f"Disparate Impact: {metric.disparate_impact()}")
🤔 Ethical Dilemma
"If a hiring algorithm trained on historical data perpetuates past discrimination, who is responsible — the developers, the company using it, or the data providers?"
Pre-processing techniques modify the training data before model training. Key approaches include reweighting, resampling, and representation learning methods like Fair Representation Learning.
In-processing methods incorporate fairness constraints during training, while post-processing adjusts model outputs to satisfy fairness criteria. Each approach has trade-offs between accuracy and fairness.
Master the quantitative tools for assessing and ensuring fair AI outcomes.
Group fairness metrics compare outcomes across demographic groups. Key metrics include Demographic Parity (equal positive prediction rates), Equalized Odds (equal TPR and FPR), and Calibration (equal precision).
# Equalized Odds Check
def equalized_odds(y_true, y_pred, group):
tpr_privileged = recall(y_true[group==1], y_pred[group==1])
tpr_unprivileged = recall(y_true[group==0], y_pred[group==0])
fpr_privileged = fpr(y_true[group==1], y_pred[group==1])
fpr_unprivileged = fpr(y_true[group==0], y_pred[group==0])
return abs(tpr_privileged - tpr_unprivileged) < 0.1
Individual fairness requires that similar individuals receive similar predictions. This requires defining an appropriate similarity metric over individuals.
Mathematical proofs show that certain fairness criteria cannot be satisfied simultaneously. Understanding these trade-offs is crucial for making informed ethical decisions.
Learn to open the "black box" and make AI decisions interpretable.
Explainable AI encompasses techniques that make model predictions understandable to humans. This includes inherently interpretable models (decision trees, linear models) and post-hoc explanation methods.
# SHAP Values for Feature Importance import shap explainer = shap.TreeExplainer(model) shap_values = explainer.shap_values(X_test) shap.summary_plot(shap_values, X_test, feature_names=features)
Local Interpretable Model-agnostic Explanations (LIME) explain individual predictions by approximating the model locally with an interpretable surrogate.
Model cards and datasheets provide standardized documentation for AI systems, including intended use cases, limitations, and ethical considerations.
Protect user privacy while maintaining model utility.
Differential privacy provides mathematical guarantees that individual data points cannot be identified from model outputs. The privacy budget (ε) controls the trade-off between privacy and accuracy.
# Differential Privacy with PyTorch
from opacus import PrivacyEngine
privacy_engine = PrivacyEngine()
model, optimizer, dataloader = privacy_engine.make_private(
module=model,
optimizer=optimizer,
data_loader=train_loader,
noise_multiplier=1.1,
max_grad_norm=1.0
)
Federated learning enables training on distributed data without centralizing sensitive information. Models are trained locally and only gradients are shared.
SMPC allows multiple parties to jointly compute a function without revealing their individual inputs to each other.
Establish organizational structures for responsible AI development.
Effective AI governance requires clear policies, defined roles, and established processes for oversight. This includes ethics review boards, impact assessments, and monitoring systems.
🤔 Governance Challenge
"How do you balance innovation speed with thorough ethical review? When does 'move fast' become 'move recklessly'?"
Regular audits ensure AI systems continue to meet ethical standards. This includes technical audits (model performance), process audits (development practices), and impact audits (real-world outcomes).
Engaging affected communities in AI development and deployment decisions is crucial for legitimacy and effectiveness.
Navigate the evolving landscape of AI regulations worldwide.
The EU AI Act establishes a risk-based regulatory framework. High-risk AI systems (healthcare, employment, credit) face strict requirements including conformity assessments, documentation, and human oversight.
/* AI Act Risk Categories */ UNACCEPTABLE: Social scoring, real-time biometric surveillance HIGH-RISK: Healthcare diagnosis, credit scoring, hiring LIMITED: Chatbots, emotion recognition (transparency only) MINIMAL: Spam filters, games (no requirements)
Compare approaches across jurisdictions: EU's comprehensive regulation, US sector-specific rules, China's algorithmic recommendations law, and emerging frameworks in other regions.

Face real ethical dilemmas and see the consequences of your choices unfold.
Your AI system for healthcare resource allocation has been deployed. Analysis shows it's denying care at higher rates to patients from lower-income zip codes — a proxy for race. The hospital board wants to keep using it because it's 15% more efficient. What do you do?
Explore documented cases where AI ethics met reality.
