ARIN 450: Data Ethics

ARIN 450 at the University of Maryland Global Campus is a study of ethics within data science, machine learning and artificial intelligence.

UMGC's catalog places the emphasis on examining data and model bias; building explainable, fair, trustable and accurate predictive modeling systems; and reporting responsible results.

Topics include the implications of human-centered machine learning and AI for decision-making in organizations and government, and the broader impact on society, including multinational and global effects.

The prerequisite is DATA 430, Foundations of Machine Learning, which tells you how the course differs from a general ethics class.

You are expected to understand how models are built, so that you can point to the exact stage where an ethical problem arises and propose a technical or procedural fix. Combining philosophical reasoning with modeling detail is what makes ARIN 450 challenging.

What ARIN 450 Covers

Key Concepts Explained

Bias Across the Pipeline

Ethical problems can arise at every stage: what data is collected, how it is labeled, which features are used, how the model is optimized and how predictions are acted on.

Fairness Metrics

Demographic parity, equal opportunity and equalized odds measure fairness differently and often cannot all be met at once. State which you use and why it fits the decision.

Responsible Reporting

Results should include uncertainty, known limitations, the populations the model was tested on and intended uses. Documentation formats such as model cards and datasheets support this.

Typical Assignments and How to Approach Them

Linking Ethics to Technical Choices

The strongest ARIN 450 papers translate principles into decisions a data team can act on. Rather than stating that a model should be fair, show which features you would remove or test as proxies, which fairness metric you would monitor and what threshold would trigger a review.

Rather than calling a model a black box, show the explanation method you would use and who would receive the explanation.

It also helps to be clear about trade-offs. Improving fairness on one metric can reduce overall accuracy or worsen another metric. Saying so openly, and explaining why the trade-off is acceptable for the context, demonstrates the mature judgment the course is designed to build.

Finally, consider who is accountable when things go wrong. Organizations and governments increasingly expect named owners for high-impact models, documented reviews before deployment and channels for affected people to question a decision.

Including governance points like these shows that you understand data ethics as an ongoing practice, not a one-off check carried out before a model goes live.

Where Students Get Stuck

• Staying abstract. Tie each ethical point to a stage in the modeling pipeline.
• Assuming removing a variable removes bias. Proxies can carry the same information.
• Forgetting deployment. How predictions are used can create harm even from a well-built model.
• Weak global perspective. The catalog mentions multinational effects; consider how rules and impacts differ across countries.

Study Tips for ARIN 450

• Revisit DATA 430 notes on evaluation metrics; fairness metrics build on them.
• Practice computing group-wise error rates on a small dataset.
• Read one real model card or datasheet to see responsible documentation in practice.
• Keep a log of well-documented incidents to use as evidence.
