Population divergence time estimation using individual lineage label switching [PDF]
G3: Genes, Genomes, Genetics, 2022 Divergence time estimation from multilocus genetic data has become common in population genetics and phylogenetics. We present a new Bayesian inference method that treats the divergence time as a random variable. The divergence time is calculated from an

Allocation Variable-Based Probabilistic Algorithm to Deal with Label Switching Problem in Bayesian Mixture Models. [PDF]
PLoS ONE, 2015 The label switching problem occurs as a result of the nonidentifiability of posterior distribution over various permutations of component labels when using Bayesian approach to estimate parameters in mixture models.

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

Fine-Tuning BERT for Multi-Label Sentiment Analysis in Unbalanced Code-Switching Text
IEEE Access, 2020 Previous research on sentiment analysis mainly focuses on binary or ternary sentiment analysis in monolingual texts. However, in today's social media such as micro-blogs, emotions are often expressed in bilingual or multilingual text called code ...

A track-before-detect labelled multi-Bernoulli particle filter with label switching [PDF]
arXiv.org, 2016 This paper presents a multitarget tracking particle filter (PF) for general track-before-detect measurement models. The PF is presented in the random finite set framework and uses a labelled multi-Bernoulli approximation.

Multiprotocol Label Switching [PDF]
Advances in Electrical and Electronic Engineering, 2007 The up to this time known networks with the IP protocol have worked as connection-less and they have not guaranteed the quality of services. Implementing the MPLS protocol, an overlay connection-oriented network with guaranteed quality of services QoS is

SERVICE MODEL OF THE VOICE TRAFFIC IN MULTIPROTOCOL LABEL SWITCHING NETWORKS [PDF]
Information and Telecommunication Sciences, 2013 This paper proposes and investigates a service model of the voice traffic in multiprotocol label switching networks. The study of Multiprotocol label switching networks (MPLS) requires a formal description of processes occurring in them, development of ...

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 ...

Boltzmann-type equations for multi-agent systems with label switching [PDF]
Kinetic and Related Models, 2020 In this paper, we propose a Boltzmann-type kinetic description of mass-varying interacting multi-agent systems. Our agents are characterised by a microscopic state, which changes due to their mutual interactions, and by a label, which identifies a group ...
