Báo cáo khoa học: "Constituent Parsing with Incremental Sigmoid Belief Networks" ppt

... syntactic parsing with latent variables based on a form of dynamic Sigmoid Belief Networks called Incremental Sigmoid Belief Networks. We demonstrate that a previous feed-forward neural network parsing ... framework for constituent parsing based on dynamic Sigmoid Belief Networks with vectors of latent variables. Exact inference with the proposed graphical model (cal...

Case assigner, a node associated with the property rec must be capable of being assigned Case, and a node associated with the property 0 must be neutral with respect to Case. The Cas...

This kind of coupled generative process can be naturally formalized with tree ... the rich literature on tree automata. This paper makes the connection concrete with a tree transducer based semantic parsing model and suggests that other models can be interpreted in a simi...
