Abstract: Let $X$ be a set of points whose coordinates are known with limited accuracy;our aim is to give a characterization of the vanishing ideal $IX$ independentof the data uncertainty. We present a method to compute a polynomial basis $B$of $IX$ which exhibits structural stability, that is, if $\widetilde X$ isany set of points differing only slightly from $X$, there exists a polynomialset $\widetilde B$ structurally similar to $B$, which is a basis of theperturbed ideal $ I\widetilde X$.
