Quasi-Monte Carlo Software
Sou-Cheng T. Choi, Fred J. Hickernell, R. Jagadeeswaran +2
Practitioners wishing to experience the efficiency gains from using low discrepancy sequences need correct, robust, well-written software. This article, based on our MCQMC 2020 tut…
Real-time Prediction of Intermediate-Horizon Automotive Collision Risk
Blake Wulfe, Sunil Chintakindi, Sou-Cheng T. Choi +3
Advanced collision avoidance and driver hand-off systems can benefit from the ability to accurately predict, in real time, the probability a vehicle will be involved in a collision…
Local Adaption for Approximation and Minimization of Univariate Functions
Sou-Cheng T. Choi, Yuhan Ding, Fred J. Hickernell +1
Most commonly used \emph{adaptive} algorithms for univariate real-valued function approximation and global minimization lack theoretical guarantees. Our new locally adaptive algori…
Report on the Third Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3)
Daniel S. Katz, Sou-Cheng T. Choi, Kyle E. Niemeyer +18
This report records and discusses the Third Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3). The report includes a description of the keynote prese…
Machine Learning for Machine Data from a CATI Network
Sou-Cheng T. Choi
This is a machine learning application paper involving big data. We present high-accuracy prediction methods of rare events in semi-structured machine log files, which are produced…
GAIL---Guaranteed Automatic Integration Library in MATLAB: Documentation for Version 2.1
Sou-Cheng T. Choi, Yuhan Ding, Fred J. Hickernell +5
Automatic and adaptive approximation, optimization, or integration of functions in a cone with guarantee of accuracy is a relatively new paradigm. Our purpose is to create an open-…
Minimal Residual Methods for Complex Symmetric, Skew Symmetric, and Skew Hermitian Systems
Sou-Cheng, Choi
While there is no lack of efficient Krylov subspace solvers for Hermitian systems, there are few for complex symmetric, skew symmetric, or skew Hermitian systems, which are increas…
MINRES-QLP: a Krylov subspace method for indefinite or singular symmetric systems
Sou-Cheng T. Choi, Christopher C. Paige, Michael A. Saunders
CG, SYMMLQ, and MINRES are Krylov subspace methods for solving symmetric systems of linear equations. When these methods are applied to an incompatible system (that is, a singular…
