We explore the use of tools from differential privacy in the design and analysis of online learning algorithms. We develop a simple and powerful analysis technique for Follow-The-Leader type algorithms under privacy-preserving perturbations. This leads to the minimax optimal algorithm for k-sparse online PCA and the best-known perturbation based algorithm for the dense online PCA. We also show that the differential privacy is the core notion of algorithm stability in various online learning problems.
