PAPERS

When it is appropriate, I organize my research perspective on certain themes into a monograph. Here are two books that have resulted.

The Informational Complexity of Learning: Perspectives on Neural Networks and Generative Grammar
Kluwer Academic Publishers , 1998.

The Computational Nature of Language Learning and Evolution
MIT Press , 2006.

Here are my other publications partially sorted by area. Some of them are downloadable.
