Sparsity in Dependency Grammar Induction
... We would like to penalize models that predict a large number of distinct dependency types. To en- force this penalty, we use the posterior regular- ization (PR) framework (Graça et al., 2007). PR is closely ... See full document

Dependency Grammar Induction with a Neural Variational Transition-Based Parser
... Universal Dependency (UD) Treebank, we find that our model with posterior regularization outperforms the best un- supervised transition-based dependency parser (Rasooli and Faili 2012), and approaches the ... See full document

A convex and feature rich discriminative approach to dependency grammar induction
... Richer feature set. In our experiments, we fo- cused on assessing the usefulness of our con- vex, discriminative approach, and thus considered only relatively simple features based on parts-of- speech. Inspired by ... See full document

Lateen EM: Unsupervised Training with Multiple Objectives, Applied to Dependency Grammar Induction
... Of the meta-heuristics that use more than a stan- dard, scalar objective, deterministic annealing (DA) (Rose, 1998) is closest to lateen EM. DA perturbs objective functions, instead of manipulating solu- tions directly. ... See full document

Unsupervised Dependency Parsing without Gold Part of Speech Tags
