In g-l-mansell/MSLDA:

Description

Run LDA as in the Blei 2003 paper

Usage

lda_original(docs, K, max_iter = 50, thresh = 1e-04, seed = NULL)

lda_original_par(
  docs,
  K,
  max_iter = 50,
  thresh = 1e-04,
  seed = NULL,
  cores = NULL
)

lda_noalpha(
  docs,
  K,
  max_iter = 50,
  thresh = 1e-04,
  seed = NULL,
  cores = NULL,
  alpha = NULL
)

Arguments

docs	a list containing all the documents, with the vocabulary encoded e.g. docs[[1]] = c(1, 5, 2) would represent the word indices from a pre-defined vocabulary
K	the number of topics to look for
max_iter	the maximum number of EM iterations to run
thresh	threshold for L convergence, (L_i - L_i-1)/L_i < thresh
seed	set a seed for the random documents to initialise beta
cores	number of cores to run the E-step in parallel, if NULL all detected cores are used
alpha	if you want to set the exchangeable Dirichlet parameter for theta, if NULL a default value of 1/K is used

Value

A list of all parameters

Functions

• lda_original_par: Runs E-step in parallel

• lda_noalpha: Alpha is fixed
