Detailed Description

Sparse Gaussian field coupling with a fixed, user-defined projection.

Unlike FieldCoupling (which learns a full weight matrix), GaussFieldCoupling uses an explicit list of GaussCoupling descriptors. Each descriptor projects activity from a source location x_i to a target location x_j with a Gaussian spread. This is useful for hand-crafted or evolution-derived projections where the exact connectivity is known in advance.
