Distributed stochastic gradient descent for link prediction in signed social networks

open access: yesEURASIP Journal on Advances in Signal Processing, 2019
This paper considers the link prediction problem defined over a signed social network, where the relationship between any two network users can be either positive (friends) or negative (foes).

Equating quantum imaginary time evolution, Riemannian gradient flows, and stochastic implementations

open access: yesPhysical Review Research
We identify quantum imaginary time evolution as a Riemannian gradient flow on the unitary group. We develop an upper bound for the error between the two evolutions that can be controlled through the step size of the Riemannian gradient descent that ...

Stochastic Adaptive Gradient Descent Without Descent

open access: yesCoRR
We introduce a new adaptive step-size strategy for convex optimization with stochastic gradient that exploits the local geometry of the objective function only by means of a first-order stochastic oracle and without any hyper-parameter tuning. The method comes from a theoretically-grounded adaptation of the Adaptive Gradient Descent Without Descent ...

On Scalable Inference with Stochastic Gradient Descent

open access: yesCoRR, 2017
In many applications involving large dataset or online updating, stochastic gradient descent (SGD) provides a scalable way to compute parameter estimates and has gained increasing popularity due to its numerical convenience and memory efficiency. While the asymptotic properties of SGD-based estimators have been established decades ago, statistical ...

Attentional-Biased Stochastic Gradient Descent

open access: yesTrans. Mach. Learn. Res., 2020
In this paper, we present a simple yet effective provable method (named ABSGD) for addressing the data imbalance or label noise problem in deep learning. Our method is a simple modification to momentum SGD where we assign an individual importance weight to each sample in the mini-batch.
