 Exponential mechanism

The Exponential Mechanism is a concept used in differential privacy, a framework for ensuring the privacy of individuals in databases while allowing for the analysis of the data. The Exponential Mechanism is particularly useful for selecting outputs or responses from a set of possible outputs based on their utility while preserving privacy. ### Key Components: 1. **Utility Function**: A function that measures how well a certain output "y" serves a specific purpose or satisfies a particular query given a dataset "D".
