Low-Rank Approximation of Weighted Tree Automata
Guillaume Rabusseau, Borja Balle, Shay B. Cohen
We describe a technique to minimize weighted tree automata (WTA), a powerful formalisms that subsumes probabilistic context-free grammars (PCFGs) and latent-variable PCFGs. Our met…
Encoding Prior Knowledge with Eigenword Embeddings
Dominique Osborne, Shashi Narayan, Shay B. Cohen
Canonical correlation analysis (CCA) is a method for reducing the dimension of data represented using two views. It has been previously used to derive word embeddings, where one vi…
Diversity in Spectral Learning for Natural Language Parsing
Shashi Narayan, Shay B. Cohen
We describe an approach to create a diverse set of predictions with spectral learning of latent-variable PCFGs (L-PCFGs). Our approach works by creating multiple spectral models wh…
Parsing Linear Context-Free Rewriting Systems with Fast Matrix Multiplication
Shay B. Cohen, Daniel Gildea
We describe a matrix multiplication recognition algorithm for a subset of binary linear context-free rewriting systems (LCFRS) with running time where i…
