[Andreas Stolcke]

The following short paper is available from the ICSI techreport archive.
Instructions for retrieval can be found at the end of this message.
Please ask me for hardcopies only if you don't have access to ftp.

The paper will be presented at the Workshop on Integrating Neural and Symbolic
Processes at AAAI-92 later this year.  We are making it generally available
mainly for the benefit of several people who had expressed interest in our
results in the past.

	Tree Matching with Recursive Distributed Representations
	Andreas Stolcke and Dekai Wu
	TR-92-025
	April 1992

		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.
