Connectionist Structure: Approaches

• Assume a fixed-valence tree, treat each of the terminals as a vector, and build a machine that can encode and decode vectors representing the tree structure.
• Assume a frame-like structure, bind roles and fillers by "multiplying" the corresponding vectors, add these products to get a representation for the whole frame. Unbind using the inverse of the "multiplication" operation.
• Implement feature binding by treating units with the same "phase" as representing features associated with a single object.
• Present an input sequence embodying some sort of structure to a trainable sequential network with an output task which requires it to derive the structure. Hope for the best.
