This is a linear operator and the input variable x is a scalar. Another example is the viscous version of Burgers equation (Olsen-Kettle, 2011). Physics Regularized Gaussian Processes Preprint Jun 2020 Zheng Wang Wei Xing Robert M. Kirby Shandian Zhe We consider incorporating incomplete physics knowledge, expressed as differential equations with latent functions, into Gaussian processes (GPs) to improve their performance, especially for limited data and extrapolation. While existing works have successfully encoded such knowledge via kernel convolution, they only apply to linear equations with analytical Greens functions. The convolution can further restrict us from fusing physics with highly expressive kernels, e.g., deep kernels. To overcome these limitations, we propose Physics Regularized Gaussian Process (PRGP) that can incorporate both linear and nonlinear equations, does not rely on Greens functions, and is free to use arbitrary kernels. Specifically, we integrate the standard GP with a generative model to encode the differential equation in a principled Bayesian hybrid framework. For efficient and effective inference, we marginalize out the latent variables and derive a simplified model evidence lower bound (ELBO), based on which we develop a stochastic collapsed inference algorithm. Our ELBO can be viewed as a posterior regularization objective. We show the advantage of our approach in both simulation and real-world applications. Four different schemes for the solution to heat equation are developed. Ames 1, Morton and Mayers 2, Cooper 3, Clive 4, Golub and Ortega 5, Burden and Faires 6, Thomas 7, Strikwerda 8, Arnold 9, Trefethen 10, Olsen-Kettle 11 and Ames 1 provide a development of finite difference methods and modern introduction to the theory of partial differential equation along with a brief coverage of numerical methods. The explicit and implicit Euler schemes are constructed and investigated for hyperbolic heat conduction equation by Ciegis 12.. Comparison of Explicit and Implicit Finite Difference Schemes on Diffusion Equation Chapter Full-text available Apr 2020 M. Adak In physics and mathematics, heat equation is a special case of diffusion equation and is a partial differential equation (PDE). Partial differential equations are useful tools for mathematical modeling. A few problems can be solved analytically, whereas difficult boundary value problem can be solved by numerical methods easily. A very popular numerical method known as finite difference methods (explicit and implicit schemes) is applied expansively for solving heat equations successfully. Explicit schemes are Forward Time and Centre Space (FTCS), Dufort and Frankel methods, whereas implicit schemes are Laasonen and Crank-Nicolson methods. In this study, explicit and implicit finite difference schemes are applied for simple one-dimensional transient heat conduction equation with Dirichlets initial-boundary conditions. MATLAB code is used to solve the problem for each scheme in fine mesh grids. FTCS scheme is conditionally stable, whereas other schemes are unconditionally stable. Convergence, stability and truncation error analysis are investigated.
