Robust Bayesian Cluster Enumeration Based on the $t$ Distribution

no code implementations29 Nov 2018 Freweyni K. Teklehaymanot, Michael Muma, Abdelhak M. Zoubir

Hence, we propose a two-step cluster enumeration algorithm that uses the expectation maximization algorithm to partition the data and estimate cluster parameters prior to the calculation of one of the robust criteria.

Bayesian Cluster Enumeration Criterion for Unsupervised Learning

1 code implementation22 Oct 2017 Freweyni K. Teklehaymanot, Michael Muma, Abdelhak M. Zoubir

We derive a new Bayesian Information Criterion (BIC) by formulating the problem of estimating the number of clusters in an observed data set as maximization of the posterior probability of the candidate models.
