Approximate Moving Least-Squares Approximation for Time-Dependent PDEs
For multivariate problems with many scattered data locations the use of radial functions has proven to be advantageous. However, using the usual radial basis function approach one needs to solve a large (possibly dense) linear system. In the moving least squares (MLS) method one obtains a best approximation of the given data in a (moving) weighted least-squares sense. The computational burden i...
متن کاملRecent Results for Moving Least Squares Approximation
We describe two experiments recently conducted with the approximate moving least squares (MLS) approximation method. On the one hand, the NFFT library of Kunis, Potts, and Steidl is coupled with the approximate MLS method to obtain a fast and accurate multivariate approximation method. The second experiment uses approximate MLS approximation in combination with a multilevel approximation algori...
متن کاملConvergence and Optimality of Adaptive Least Squares Finite Element Methods
The first-order div least squares finite element methods (LSFEMs) allow for an immediate a posteriori error control by the computable residual of the least squares functional. This paper establishes an adaptive refinement strategy based on some equivalent refinement indicators. Since the first-order div LSFEMmeasures the flux errors inH(div), the data resolution error measures the L2 norm of th...
متن کاملConvergence of Least Squares Temporal Difference Methods Under General Conditions
We consider approximate policy evaluation for finite state and action Markov decision processes (MDP) in the off-policy learning context and with the simulation-based least squares temporal difference algorithm, LSTD(λ). We establish for the discounted cost criterion that the off-policy LSTD(λ) converges almost surely under mild, minimal conditions. We also analyze other convergence and bounded...
متن کاملStable Moving Least-Squares
It is a common procedure for scattered data approximation to use local polynomial fitting in the least-squares sense. An important instance is the Moving Least-Squares where the corresponding weights of the data site vary smoothly, resulting in a smooth approximation. In this paper we build upon the techniques presented by Wendland and present a somewhat simpler error analysis of the MLS approx...
