Bernstein polynomial estimation provides a robust nonparametric technique for approximating both density and distribution functions. Based on the properties of Bernstein polynomials, which ...

Within this framework, polynomial threshold functions (PTFs) represent a class of Boolean functions expressed as the sign of a polynomial, bridging the gap between algebraic methods and ...

A robust procedure is developed for estimating density functions from data. It requires the existence of a parametric function, called the key function, to give a first approximation to the density ...
