A Bochner Formula on Path Space for the Ricci Flow
Christopher Kennedy
We generalize the classical Bochner formula for the heat flow on evolving manifolds to an infinite-dimensional Bochner formula for martingales on paraboli…
Greedy Variance Estimation for the LASSO
Christopher Kennedy, Rachel Ward
Recent results have proven the minimax optimality of LASSO and related algorithms for noisy linear regression. However, these results tend to rely on variance estimators that are i…
Fast Cross-Polytope Locality-Sensitive Hashing
Christopher Kennedy, Rachel Ward
We provide a variant of cross-polytope locality sensitive hashing with respect to angular distance which is provably optimal in asymptotic sensitivity and enjoys $\mathcal{O}(d \ln…
Approximating the Little Grothendieck Problem over the Orthogonal and Unitary Groups
Afonso S. Bandeira, Christopher Kennedy, Amit Singer
The little Grothendieck problem consists of maximizing over binary variables , where C is a positive semidefinite matrix. In this paper we f…
