Bayesian Analysis of Dynamic Linear Topic Models
In dynamic topic modeling, the proportional contribution of a topic to a document depends on the temporal dynamics of that topic’s overall prevalence in the corpus. We extend the Dynamic Topic Model of Blei and Lafferty (2006) by explicitly modeling document-level topic proportions with covariates and dynamic structure that includes polynomial trends and periodicity. A Markov Chain Monte Carlo ...
متن کاملBayesian Model Averaging of Dynamic Linear Models
In this paper we aim to compare the performance of three different Bayesian model averaging (or mixture) methods applied to regression dynamic linear models for beverage data from Zimbabwe. The models are chosen to reflect different plausible causal structures of association between beverage sales and other variables, thought to influence beverage sales, such as prices, temperature and maize cr...
متن کاملSparsity-Promoting Bayesian Dynamic Linear Models
Sparsity-promoting priors have become increasingly popular over recent years due to an increased number of regression and classification applications involving a large number of predictors. In time series applications where observations are collected over time, it is often unre-alistic to assume that the underlying sparsity pattern is fixed. We propose here an original class of flexible Bayesia...
متن کاملCost Analysis of Acceptance Sampling Models Using Dynamic Programming and Bayesian Inference Considering Inspection Errors
Acceptance Sampling models have been widely applied in companies for the inspection and testing the raw material as well as the final products. A number of lots of the items are produced in a day in the industries so it may be impossible to inspect/test each item in a lot. The acceptance sampling models only provide the guarantee for the producer and consumer that the items in the lots are acco...
متن کاملBayesian Checking for Topic Models
Real document collections do not fit the independence assumptions asserted by most statistical topic models, but how badly do they violate them? We present a Bayesian method for measuring how well a topic model fits a corpus. Our approach is based on posterior predictive checking, a method for diagnosing Bayesian models in user-defined ways. Our method can identify where a topic model fits the ...
