Implements Sequential Latent Dirichlet allocation (Sequential LDA). textmodel_seqlda() allows the users to classify sentences of texts. It considers the topics of previous document in inferring the topics of currency document. textmodel_seqlda() is a shortcut equivalent to textmodel_lda(gamma = 0.5). Seeded Sequential LDA is textmodel_seededlda(gamma = 0.5).

Usage

textmodel_seqlda(
  x,
  k = 10,
  max_iter = 2000,
  auto_iter = FALSE,
  alpha = 0.5,
  beta = 0.1,
  batch_size = 1,
  model = NULL,
  verbose = quanteda_options("verbose")
)

Arguments

x

the dfm on which the model will be fit.

k

the number of topics.

max_iter

the maximum number of iteration in Gibbs sampling.

auto_iter

if TRUE, stops Gibbs sampling on convergence before reaching max_iter. See details.

alpha

the values to smooth topic-document distribution.

beta

the values to smooth topic-word distribution.

batch_size

split the corpus into the smaller batches (specified in proportion) for distributed computing; it is disabled when a batch include all the documents batch_size = 1.0. See details.

model

a fitted LDA model; if provided, textmodel_lda() inherits parameters from an existing model. See details.

verbose

logical; if TRUE print diagnostic information during fitting.

Value

The same as textmodel_lda()
