      Bun, Mark Mar; Ullman, Jonathan; Vadhan, Salil P. (Association of Computing Machinery, 2014)
      We show new lower bounds on the sample complexity of (ε, δ)-differentially private algorithms that accurately answer large sets of counting queries. A counting query on a database D ∈ ({0, 1}d)n has the form "What fraction ...
    • Finite dimensional FRI 

      Onativia, Jon; Lu, Yue; Dragoni, Pier Luigi (Institute of Electrical and Electronics Engineers, 2014)
      Traditional Finite Rate of Innovation (FRI) theory has considered the problem of sampling continuous-time signals. This framework can be naturally extended to the case where the input is a discrete-time signal. Here we ...
    • Finite Element Model of Branched Ruptures Including Off-Fault Plasticity 

      DeDontney, Nora; Rice, James R.; Dmowska, Renata (Seismological Society of America, 2012)
      Fault intersections are a geometric complexity that frequently occurs in nature. Here we focus on earthquake rupture behavior when a continuous, planar main fault has a second fault branching off of it. We use the finite ...
