Fitting sparse multidimensional data with low-dimensional terms
Description
Abstract An algorithm that fits a continuous function to sparse multidimensional data is presented. The algorithm uses a representation in terms of lower-dimensional component functions of coordinates defined in an automated way and also permits dimensionality reduction. Neural networks are used to construct the component functions. Title of program: RS_HDMR_NN Catalogue Id: AEEI_v1_0 Nature of problem Fitting a smooth, easily integratable and differentiatable, function to a very sparse (~2-3 points per dimension) multidimensional (D >= 6) large (~10 4 -10 5 data) dataset.
