In the previous posts we covered in detail the theoretical background of the method and we described its mathematical representationsmu and ways to construct it. In this post we will try to link the theory with the practice by introducing two models DPMM: the Dirichlet Multivariate Normal Mixture Model which can be used to cluster Gaussian data and the Dirichlet-Multinomial Mixture Model which is used to cluster documents: ...

The target of this article is to define the Dirichlet Process Mixture Models and discuss the use of Chinese Restaurant Process and Gibbs Sampling: http://blog.datumbox.com/the-dirichlet-process-mixture-model/ Vasilis Vryniotis <en-support@xing.com> http://www.xing.com/app/forum?op=showarticles&id=46672637&articleid=46672637#46672637 Mon, 23 Jun 2014 08:48:11 GMT http://www.xing.com/app/forum?op=showarticles&id=46606094&articleid=46606094#46606094 The 2014 2nd International Symposium on Computational and Business Intelligence (ISCBI-II 2014) will be held in New Delhi, India during December 7-8, 2014. The aim as well as objective of ISCBI-II 2014 is to present the latest research and results of scientists working in the fields related to Computational and Business Intelligence. This Symposium provides opportunities for the delegates to exchange new ideas and application through face-to-face discussions, to establish business or research ...

In the previous article we had an overview of several Cluster Analysis techniques and we discussed some of the problems/limitations that rise by using them. Moreover we briefly presented the Dirichlet Process Mixture Models, we talked about why they are useful and we presented some of their applications. In this article I will briefly present some important distributions that we will need, we will use ...

The DPMMs is a “fully-Bayesian” unsupervised learning technique which unlike other Cluster Analysis methods does not require us to predefine the total number of clusters within our data. Large companies, such as Google, use these infinite Dirichlet mixture models in a variety of applications including Document ...
