ML Ethics — Building Fair, Transparent, and Accountable Systems

In this module, you'll explore the ethical considerations in machine learning, including fairness, bias detection, and responsible AI practices. Learn how to build systems that are transparent, accountable, and compliant with regulations.

Fairness and Bias Detection — Understanding and mitigating algorithmic bias
Interpretability and Transparency — Making model decisions explainable
Responsible AI Practices — Ensuring ethical deployment and compliance

"Ethics is not an afterthought — it's a core requirement for trustworthy AI."

ML Ethics — Responsible AI

AI systems must be fair, transparent, and accountable. Ethics is not optional — it's a legal requirement in many jurisdictions.

Fairness

DfFairness in ML

Fairness in machine learning ensures that models do not discriminate against individuals or groups based on protected attributes such as race, gender, or age.

Demographic parity: Equal positive rates across groups
Equal opportunity: Equal true positive rates
Equalized odds: Equal TPR and FPR
Individual fairness: Similar individuals treated similarly

Sources of Bias

Historical bias in training data
Representation bias (underrepresented groups)
Measurement bias (proxy variables)
Aggregation bias (one model for diverse groups)

Types of Algorithmic Bias

Fairness Metrics

Demographic Parity

P(\hat{Y}=1 | A=a) = P(\hat{Y}=1 | A=b) \\quad \forall a,b

Here,

$\hat{Y}$ =Model prediction
$A$ =Protected attribute (e.g., gender, race)

Equalized Odds

P(\hat{Y}=1 | A=a, Y=y) = P(\hat{Y}=1 | A=b, Y=y) \\quad \forall a,b,y

Here,

$Y$ =True label
$\hat{Y}$ =Model prediction

Fairness Metrics Comparison

Ethical AI Framework

DfResponsible AI Pillars

Fairness: Mitigate bias across protected groups
Transparency: Explainable decisions and model behavior
Accountability: Human oversight and audit trails
Privacy: Data protection and differential privacy
Safety: Robustness and adversarial resilience
