Dealing With Label Switching in Mixture Models [PDF]

open access: bronzeJournal 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 ...

Population divergence time estimation using individual lineage label switching [PDF]

open access: yesG3: 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]

open access: greenJournal 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]

open access: yesPLoS 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 label switching

open access: bronzeOptical 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]

open access: yesJournal 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

open access: yesIEEE 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 ...

Improving Label Space Usage for Ethernet Label Switched Paths [PDF]

open access: green2008 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).

Mean-field analysis of multi-population dynamics with label switching [PDF]

open access: greenSIAM Journal on Mathematical Analysis, 2019
The mean-field analysis of a multi-population agent-based model is performed. The model couples a particle dynamics driven by a nonlocal velocity with a Markow-type jump process on the probability that each agent has of belonging to a given population. A

Effects of Switching to the Tobacco Heating System 2.2 Menthol, Smoking Abstinence, or Continued Cigarette Smoking on Biomarkers of Exposure: A Randomized, Controlled, Open-Label, Multicenter Study in Sequential Confinement and Ambulatory Settings (Part 1) [PDF]

open access: hybridNicotine & Tobacco Research, 2016
Introduction The menthol Tobacco Heating System 2.2 (mTHS) is a newly developed candidate modified-risk tobacco product intended to reduce exposure to the harmful and potentially harmful constituents (HPHCs) of conventional cigarette (CC) smoke.
