We study generalized Horn-Kapranov rational parametrizations of inhomogeneous sparse discriminants from both a theoretical and an algorithmic perspective. We show that all these parametrizations are birational and prove some results on the corresponding implicit equations. We also propose a combinatorial algorithm to compute the degree of inhomogeneous discriminantal surfaces associated to uniform matrices.

Sparse implicitization by interpolation: Characterizing non-exactness and an application to computing discriminants
TLDR
The method may yield a multiple of the implicit equation: it is characterized and quantify this situation by relating the nullspace dimension to the predicted support and its geometry, thus yielding a method of sparse approximate implicitization, which is important in tackling larger problems.
