摘要：

We consider the problem of interpolation by linear combinations of ridge functions. A ridge function is a function of the form f{hook}(a · x) where f{hook}: R → R, a ∈ Rd\{0} is a fixed vector, and x ∈ Rd is the variable. The solvability of the interpolation problem is characterized by geometric properties. © 1993 Academic Press. All rights reserved.
