Accelerating stochastic gradient descent using predictive variance reduction

R Johnson, T Zhang - Advances in neural information …, 2013 - proceedings.neurips.cc
Stochastic gradient descent is popular for large scale optimization but has slow convergence
asymptotically due to the inherent variance. To remedy this problem, we introduce an …

[PDF][PDF] A framework for learning predictive structures from multiple tasks and unlabeled data.

RK Ando, T Zhang, P Bartlett - Journal of machine learning research, 2005 - jmlr.org
One of the most important issues in machine learning is whether one can improve the
performance of a supervised learning algorithm by including unlabeled data. Methods that use …

A proximal stochastic gradient method with progressive variance reduction

L Xiao, T Zhang - SIAM Journal on Optimization, 2014 - SIAM
We consider the problem of minimizing the sum of two convex functions: one is the average
of a large number of smooth component functions, and the other is a general convex function …

Local and global energy release rates for an electrically yielded crack in a piezoelectric ceramic

H Gao, TY Zhang, P Tong - Journal of the Mechanics and Physics of Solids, 1997 - Elsevier
Structural reliability concerns of various electromechanical devices call for a better
understanding of the mechanisms of fracture in piezoelectric ceramics subjected to combined …

Superconductivity in one-atomic-layer metal films grown on Si (111)

T Zhang, P Cheng, WJ Li, YJ Sun, G Wang, XG Zhu… - Nature Physics, 2010 - nature.com
The two-dimensional (2D) superconducting state is a fragile state of matter susceptible to
quantum phase fluctuations. Although superconductivity has been observed in ultrathin metal …

Spatial–temporal recurrent neural network for emotion recognition

T Zhang, W Zheng, Z Cui, Y Zong… - IEEE transactions on …, 2018 - ieeexplore.ieee.org
In this paper, we propose a novel deep learning framework, called spatial–temporal recurrent
neural network (STRNN), to integrate the feature learning from both spatial and temporal …

A measure of spatial stratified heterogeneity

JF Wang, TL Zhang, BJ Fu - Ecological indicators, 2016 - Elsevier
Spatial stratified heterogeneity, referring to the within-strata variance less than the between
strata-variance, is ubiquitous in ecological phenomena, such as ecological zones and many …

Involution: Inverting the inherence of convolution for visual recognition

…, C Wang, X Li, Q She, L Zhu, T Zhang… - Proceedings of the …, 2021 - openaccess.thecvf.com
Convolution has been the core ingredient of modern neural networks, triggering the surge
of deep learning in vision. In this work, we rethink the inherent principles of standard …

Solving large scale linear prediction problems using stochastic gradient descent algorithms

T Zhang - Proceedings of the twenty-first international conference …, 2004 - dl.acm.org
Linear prediction methods, such as least squares for regression, logistic regression and support
vector machines for classification, have been extensively used in statistics and machine …

[HTML][HTML] COVID-19 immune features revealed by a large-scale single-cell transcriptome atlas

…, C Yin, D Yu, K Yu, J Yuan, B Zhang, P Zhang, T Zhang… - Cell, 2021 - cell.com
A dysfunctional immune response in coronavirus disease 2019 (COVID-19) patients is a
recurrent theme impacting symptoms and mortality, yet a detailed understanding of pertinent …
