Dealing With Label Switching in Mixture Models [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2000 Summary In a Bayesian analysis of finite mixture models, parameter estimation and clustering are sometimes less straightforward than might be expected. In particular, the common practice of estimating parameters by their posterior mean, and summarizing joint posterior distributions by marginal distributions, often leads to nonsensical ...

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

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

The Effect of Food Label Use on Nutrient Intakes: An Endogenous Switching Regression Analysis [PDF]
Journal of Agricultural and Resource Economics, 2000 This study examines the impact of consumers' use of food labels on selected nutrient intakes of Americans. Endogenous switching regression techniques are employed to control for heterogeneity in the label use decision.

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.

Optical Fiber Communication Conference and International Conference on Quantum Information, 2001 Summary form only given. The design and implementation of a optical label switched router for packet switched WDM networks will be presented. The algorithms of generating optical labels, look-up tables, routing protocols, and a scaleable network architecture similar to IP/MPLS in optical domain will also be discussed.

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]
IEEE Transactions on Aerospace and Electronic Systems, 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.

Improving Label Space Usage for Ethernet Label Switched Paths [PDF]
2008 IEEE International Conference on Communications, 2008 Ethernet is becoming the dominant aggregation technology for carrier transport networks; however, as it is a LAN technology, native bridged ethernet does not fulfill all the carrier requirements. One of the schemes proposed by the research community to make ethernet fulfill carrier requirements is ethernet VLAN-label switching (ELS).
