Polyhedral Analysis of Symmetric Multilinear Polynomials over Box Constraints

no code implementations11 Dec 2020 Yibo Xu, Warren Adams, Akshay Gupte

These conditions are applied to obtain envelopes for two classes: symmetric supermodular functions and multilinear monomials with reflection symmetry, thereby yielding alternate proofs to the literature.

Parallel and distributed asynchronous adaptive stochastic gradient methods

1 code implementation21 Feb 2020 Yangyang Xu, Colin Sutcher-Shepard, Yibo Xu, Jie Chen

The proposed method is tested on both convex and non-convex machine learning problems, and the numerical results demonstrate its clear advantages over the sync counterpart and the async-parallel nonadaptive SGM.

Katyusha Acceleration for Convex Finite-Sum Compositional Optimization

no code implementations24 Oct 2019 Yibo Xu, Yangyang Xu

However, the additional compositional structure prohibits easy access to unbiased stochastic approximation of the gradient, so directly applying the SGM to a finite-sum compositional optimization problem (COP) is often inefficient.

Compressed Domain Image Classification Using a Dynamic-Rate Neural Network

no code implementations28 Jan 2019 Yibo Xu, Weidi Liu, Kevin F. Kelly

Compressed domain image classification performs classification directly on compressive measurements acquired from the single-pixel camera, bypassing the image reconstruction step.
