    A set function on a ground set of size n is approximately modular if it satisfies every modularity requirement to within an additive error, approximate modularity is the set analog of approximate linearity. In this paper ...
  • Chierichetti, Flavio; Dasgupta, Anirban; Kumar, Ravi; Lattanzi, Silvio (ACM Digital Library, 2015-01-02)
    In this paper we consider the problem of learning a mixture of permutations, where each component of the mixture is generated by a stochastic process. Learning permutation mixtures arises in practical settings when a set ...
  • Chierichetti, Flavio; Dasgupta, Anirban; Kumar, Ravi; Lattanzi, Silvio (DROPS, 2014-09-04)
    The Mallows model is a classical model for generating noisy perturbations of a hidden permutation, where the magnitude of the perturbations is determined by a single parameter. In this work we consider the following ...
