We present an approach to the structure unification problem using distributed representations of hierarchical objects. Binary trees are encoded using the recursive auto-association method (RAAM), and a unification network is trained to perform the tree matching operation on the RAAM representations. It turns out that this restricted form of unification can be learned without hidden layers and producing good generalization if we allow the error signal from the unification task to modify both the unification network and the RAAM representations themselves.
