Max-Margin Works while Large Margin Fails: Generalization without Uniform Convergence

no code implementations16 Jun 2022 Margalit Glasgow, Colin Wei, Mary Wootters, Tengyu Ma

Nagarajan and Kolter (2019) show that in certain simple linear and neural-network settings, any uniform convergence bound will be vacuous, leaving open the question of how to prove generalization in settings where UC fails.

Asynchronous Distributed Optimization with Stochastic Delays

no code implementations22 Sep 2020 Margalit Glasgow, Mary Wootters

This complexity sits squarely between the complexity $\tilde{O}\left(\left(n + \kappa\right)\log(1/\epsilon)\right)$ of SAGA \textit{without delays} and the complexity $\tilde{O}\left(\left(n + m\kappa\right)\log(1/\epsilon)\right)$ of parallel asynchronous algorithms where the delays are \textit{arbitrary} (but bounded by $O(m)$), and the data is accessible by all.

Approximate Gradient Coding with Optimal Decoding

no code implementations17 Jun 2020 Margalit Glasgow, Mary Wootters

Recent work has studied approximate gradient coding, which concerns coding schemes where the replication factor of the data is too low to recover the full gradient exactly.

Strategic Classification

Jury designs a classifier, and Contestant receives an input to the classifier, which he may change at some cost.

Fast matrix completion without the condition number

no code implementations15 Jul 2014 Moritz Hardt, Mary Wootters

We give the first algorithm for Matrix Completion whose running time and sample complexity is polynomial in the rank of the unknown target matrix, linear in the dimension of the matrix, and logarithmic in the condition number of the matrix.
