摘要:The talk is concerned with the multivariate stochastic collocation methods on unstructured grids. The motivation for such a study is the applications in parametric Uncertainty Quantification (UQ). We shall first give a general framework of stochastic collocation methods, which include approaches such as compressed sensing, least-squares, and polynomial interpolation. Particular attention will be then given to the least-squares approach, and we will  

review recent progresses. The talk is based on joint works with A. Narayan (Umass, USA),  

J. Jackman (Sandia, USA), Z. Xu (AMSS, CAS)  

周涛,中国科学院数学与系统科学研究院研究员,主要研究方向为随机计算、不确定性定量化,学术论文发表在SIAM J. Sci. Comput、J. Comput. Phys、J. Sci. Comput.、J. Comput. Math.等国内外权威刊物上,主持国家自然科学基金多项。
