Experiments with Latent Dirichlet Allocation
نویسنده
چکیده
Latent Dirichlet Allocation is a generative topic model for text. In this report, we implement collapsed Gibbs sampling to learn the topic model. We test our implementation on two data sets: classic400 and Psychological Abstract Review. We also discuss the different evaluation of goodness-of-fit of the models how parameter settings interact with the goodness-of-fit.

متن کاملLatent Dirichlet Allocation with Topic-in-Set Knowledge
Latent Dirichlet Allocation is an unsupervised graphical model which can discover latent topics in unlabeled data. We propose a mechanism for adding partial supervision, called topic-in-set knowledge, to latent topic modeling. This type of supervision can be used to encourage the recovery of topics which are more relevant to user modeling goals than the topics which would be recovered otherwise...
متن کاملLanguage model adaptation using latent dirichlet allocation and an efficient topic inference algorithm
We present an effort to perform topic mixture-based language model adaptation using latent Dirichlet allocation (LDA). We use probabilistic latent semantic analysis (PLSA) to automatically cluster a heterogeneous training corpus, and train an LDAmodel using the resultant topicdocument assignments. Using this LDA model, we then construct topic-specific corpora at the utterance level for interpol...

In this paper, we propose an acceleration of collapsed variational Bayesian (CVB) inference for latent Dirichlet allocation (LDA) by using Nvidia CUDA compatible devices. While LDA is an efficient Bayesian multi-topic document model, it requires complicated computations for parameter estimation in comparison with other simpler document models, e.g. probabilistic latent semantic indexing, etc. T...
