This book provides an insider’s view of how to combine two mature fields, scientific computing and Bayesian inference, into a powerful language leveraging the capabilities of both components for computational efficiency, high resolution power and uncertainty quantification ability. The impact of Bayesian scientific computing has been particularly significant in the area of computational inverse problems where the data are often scarce or of low quality, but some characteristics of the unknown solution may be available a priori. The ability to combine the flexibility of the Bayesian probabilistic framework with efficient numerical methods has contributed to the popularity of Bayesian inversion, with the prior distribution being the counterpart of classical regularization. However, the interplay between Bayesian inference and numerical analysis is much richer than providing an alternative way to regularize inverse problems, as demonstrated by the discussion of time dependent problems, iterative methods, and sparsity promoting priors in this book. The quantification of uncertainty in computed solutions and model predictions is another area where Bayesian scientific computing plays a critical role. This book demonstrates that Bayesian inference and scientific computing have much more in common than what one may expect, and gradually builds a natural interface between these two areas.Applied Mathematical Sciences,2196-968X ;215MathematicsData processingAlgebras, LinearComputer scienceMathematicsComputational Science and EngineeringComputational Mathematics and Numerical AnalysisLinear AlgebraMathematics of ComputingMathematicsData processing.Algebras, Linear.Computer scienceMathematics.Computational Science and Engineering.Computational Mathematics and Numerical Analysis.Linear Algebra.Mathematics of Computing.519.542519.542Calvetti Daniela524724Somersalo ErkkiMiAaPQMiAaPQMiAaPQBOOK9910682585103321Bayesian scientific computing3291891UNINA
