Design Theory and some Forbidden Configurations
R. P. Anstee, Farzin Barekat, Zachary Pellegrin
In this paper we relate t-designs to a forbidden configuration problem in extremal set theory. Let 1_t 0_l denote a column of t 1's on top of l 0's. We assume t>l. Let q. (1_t 0_l)…
Design Theory and Some Non-simple Forbidden Configurations
R. P. Anstee, Farzin Barekat
Let 1_k 0_l denote the (k+l)\times 1 column of k 1's above l 0's. Let q. (1_k 0_l) $ denote the (k+l)xq matrix with q copies of the column 1_k0_l. A 2-design S_λ(2,3,v) can be defi…
DP-LSSGD: A Stochastic Optimization Method to Lift the Utility in Privacy-Preserving ERM
Bao Wang, Quanquan Gu, March Boedihardjo +2
Machine learning (ML) models trained by differentially private stochastic gradient descent (DP-SGD) have much lower utility than the non-private ones. To mitigate this degradation,…
Laplacian Smoothing Gradient Descent
Stanley Osher, Bao Wang, Penghang Yin +4
We propose a class of very simple modifications of gradient descent and stochastic gradient descent. We show that when applied to a large variety of machine learning problems, rang…
Compressed Wannier modes found from an regularized energy functional
Farzin Barekat, Ke Yin, Russel E. Caflisch +3
We propose a method for calculating Wannier functions of periodic solids directly from a modified variational principle for the energy, subject to the requirement that the Wannier…
Projection to the Set of Shift Orthogonal Functions
Farzin Barekat, Rongjie Lai, Ke Yin +3
This paper presents a fast algorithm for projecting a given function to the set of shift orthogonal functions (i.e. set containing functions with unit norm that are orthogona…
