Whether or not the Sparsest Cut problem admits an efficient 𝑂(1)-approximation algorithm is a fundamental algorithmic question with connections to geometry and the Unique Games Conjecture. We design an 𝑂(1)-approximation algorithm to Sparsest Cut for the...

The standard definition of differential privacy (DP) ensures that a mechanism's output distribution...
Many intended uses of differential privacy involve a continual mechanism that is set up to run continuously over a long period of time, making more statistical releases as either queries come in or the dataset is updated. In this paper, we give the first...
