label.switching: An R Package for Dealing with the Label Switching Problem in MCMC Outputs [PDF]
Journal of Statistical Software, 2016 Label switching is a well-known and fundamental problem in Bayesian estimation of mixture or hidden Markov models. In case that the prior distribution of the model parameters is the same for all states, then both the likelihood and posterior distribution

Alleviating Label Switching with Optimal Transport [PDF]
arXiv, 2019 Label switching is a phenomenon arising in mixture model posterior inference that prevents one from meaningfully assessing posterior statistics using standard Monte Carlo procedures. This issue arises due to invariance of the posterior under actions of a group; for example, permuting the ordering of mixture components has no effect on the likelihood ...

Overfitting Bayesian Mixture Models with an Unknown Number of Components. [PDF]
PLoS ONE, 2015 This paper proposes solutions to three issues pertaining to the estimation of finite mixture models with an unknown number of components: the non-identifiability induced by overfitting the number of components, the mixing limitations of standard Markov ...

A new scheme for interconnecting LANs with label switching bridges [PDF]
The IEEE Conference on Local Computer Networks 30th Anniversary (LCN'05)l, 2005 Ethernet, which has traditionally been the dominant technology in Local Area Networks, is now facing new challenges due to the fact that networks have scaled and today's applications require more bandwidth and increased robustness against failures.

Label-controlled optical switching nodes [PDF]
, 2006 Optical networks are evolving from initially static optical circuits and subsequently optical circuit switching towards optical packet switching in order to take advan- tage of the high transport capacity made available by WDM systems in a more °exible and e±cient way.

Bayesian Solutions to the Label Switching Problem [PDF]
, 2009 The label switching problem, the unidentifiability of the permutation of clusters or more generally latent variables, makes interpretation of results computed with MCMC sampling difficult. We introduce a fully Bayesian treatment of the permutations which performs better than alternatives.

A viral load-based model for epidemic spread on spatial networks
Mathematical Biosciences and Engineering, 2021 In this paper, we propose a Boltzmann-type kinetic model of the spreading of an infectious disease on a network. The latter describes the connections among countries, cities or districts depending on the spatial scale of interest.
