Basis-Function Trees as a Generalization of Local Variable Selection Methods for Function Approximation
–Neural Information Processing Systems
Function approximation on high-dimensional spaces is often thwarted by a lack of sufficient data to adequately "fill" the space, or lack of sufficient computational resources. The technique of local variable selection provides a partial solution to these problems by attempting to approximate functions locally using fewer than the complete set of input dimensions.
