A scalable parallel FEM surface fitting algorithm for data mining
The development of automatic techniques to process and detect patterns in very large data sets is a major task in data mining. An essential subtask is the interpolation of surfaces, which can be done with multivariate regression. Thin plate splines provide a very good method to determine an approximating surface. Unfortunately, obtaining standard thin plate splines requires the solution of a dense linear system of order n, where n is the number of observations. Thus, standard thin plate splines...[Show more]
