Unsupervised and Constrained Dirichlet Process Mixture Models for Verb 


Speaker: Andreas Vlachos Computer Laboratory Cambridge 


University Abstract:  

In this work we apply Dirichlet Process Mixture Models (DPMMs) to a learning task in natural language processing (NLP): lexical-semantic verb clustering. Furthermore, we propose a novel method of guiding the DPMM towards a particular clustering solution using pairwise constraints. The quantitative and qualitative evaluation performed highlights the benefits of both standard and constrained DPMMs compared to previously used approaches

Tutorial on Grammar induction

key words:


Bayesian learning

signal '--> concept



making up a grammar:


we start with a grammar where each rule describe one of the sentence of the corpus: so there are the same number of non terminal nodes/symbols as a terminal nodes or words at the corpus.


2 operations:

Merge - > reduce the number of nodes.

Chinking - > increase the number of nodes.


Selecting operations the grammar become more and more open.



The objective is to compare trees analysis, so the accuracy is measure as how near get the tree analysis of the emerge parser compared with the tree of a stablish parser.

(??? not very clear point)


for artificial grammars it give a very good results.

For real data sets not very good.

Version 2.09, 15-aug-2008 (latest): Interface to XTAL regression package was added the STPRtool. XTAL implements the following regression methods:
  • Projection pursuit regression (SMART)
  • Multilayer perceptron
  • Multivariate adaptive regression splines
  • k-nearest neighbors and Constrained topological mapping
  • Constrained topological mapping
