Differential Privacy: Sensitivity, Metrics, and Private Statistical Analysis

Reason from differential-privacy definitions to sensitivity and private statistical releases.

Looking for step-by-step tutorials for individual AI tools?

Course overview

Build foundations in differential privacy, examine metrics related to local sensitivity, compare formal privacy definitions, and study private multi-party sketching for large-scale statistics. Emphasis is on neighboring-dataset assumptions, composition, utility, and the distinction between a mathematical guarantee and implementation evidence. Original study notes are not transcripts.

State the neighboring-dataset relation, privacy parameters, and randomized mechanism behind a DP claim. Explain how sensitivity and distance metrics influence noise required for a private release. Evaluate composition, utility, and threat-model assumptions in private statistical protocols.

Familiarity with probability, statistics, and basic algorithms is recommended. Experience with randomized mechanisms or security concepts is useful but not required; comfort with mathematical definitions is expected.
