Adjusting Leverage Scores by Row Weighting: A Practical Approach to Coherent Matrix Completion
Shusen Wang, Tong Zhang, Zhihua Zhang
Low-rank matrix completion is an important problem with extensive real-world applications. When observations are uniformly sampled from the underlying matrix entries, existing meth…
Joint Multi-Cell Resource Allocation Using Pure Binary-Integer Programming for LTE Uplink
Tong Zhang, Xiaofeng Tao, Qimei Cui
Due to high system capacity requirement, 3GPP Long Term Evolution (LTE) is likely to adopt frequency reuse factor 1 at the cost of suffering severe inter-cell interference (ICI). O…
Accelerating Minibatch Stochastic Gradient Descent using Stratified Sampling
Peilin Zhao, Tong Zhang
Stochastic Gradient Descent (SGD) is a popular optimization method which has been applied to many important machine learning tasks such as Support Vector Machines and Deep Neural N…
Stochastic Optimization with Importance Sampling
Peilin Zhao, Tong Zhang
Uniform sampling of training data has been commonly used in traditional stochastic optimization algorithms such as Proximal Stochastic Gradient Descent (prox-SGD) and Proximal Stoc…
