Stochastic Conjugate Gradient Algorithm with Variance Reduction
Xiao-Bo Jin, Xu-Yao Zhang, Kaizhu Huang +1
Conjugate gradient (CG) methods are a class of important methods for solving linear equations and nonlinear optimization problems. In this paper, we propose a new stochastic CG alg…
T-DB: Toward Fully Functional Transparent Encrypted Databases in DBaaS Framework
Xiaofei Wang, Qianhong Wu, Yuqing Zhang
Individuals and organizations tend to migrate their data to clouds, especially in a DataBase as a Service (DBaaS) pattern. The major obstacle is the conflict between secrecy and ut…
Approximations and Bounds for (n, k) Fork-Join Queues: A Linear Transformation Approach
Huajin Wang, Jianhui Li, Zhihong Shen +1
Compared to basic fork-join queues, a job in (n, k) fork-join queues only needs its k out of all n sub-tasks to be finished. Since (n, k) fork-join queues are prevalent in popular…
Efficient reconstruction of CASCI-type wave functions for a DMRG state using quantum information theory and genetic algorithm
Zhen Luo, Yingjin Ma, Chungen Liu +1
We improve the methodology to construct a complete active space-configuration interaction (CAS-CI) expansion for density-matrix renormalization group (DMRG) wave function using mat…
