This describes the behavior of reuse of points in constructing polynomial chaos expansion models.


  • Alias: reuse_samples

  • Arguments: None

  • Default: no sample reuse in coefficient estimation


The reuse_points option controls the reuse behavior of points for various types of polynomial chaos expansions, including: collocation_points, collocation_ratio, expansion_samples, or orthogonal_least_interpolation. If any of these approaches are specified to create a set of points for the polynomial chaos expansion, one can specify reuse_points so that any points that have been previously generated (for example, from the import_points file) can be reused.
