new_simple_lda_config: new_simple_lda_config
In lejon/pcldar: R Wrapper for our Partially Collapsed LDA (PCLDA)

Create a new LDA config file

new_simple_lda_config(dataset_fn, nr_topics = 20, alpha = 0.01,
  beta = (nr_topics/50), iterations = 2000, rareword_threshold = 10,
  optim_interval = -1, stoplist_fn = "stoplist.txt",
  topic_interval = 10, tmpdir = "/tmp",
  topic_priors = "stoplist.txt")

`dataset_fn`	filename of dataset (in LDA format)
`nr_topics`	number of topics to use
`alpha`	symmetric alpha prior
`beta`	symmetric beta prior
`iterations`	number of iterations to sample
`rareword_threshold`	min. number of occurences of a word to be kept
`optim_interval`	how often to do hyperparameter optimization (default is off = -1)
`stoplist_fn`	filenname of stoplist file (one word per line) (default "stoplist.txt")
`topic_interval`	how often to print topic info during sampling
`tmpdir`	temporary directory for intermediate storage of logging data (default "tmp")
`topic_priors`	text file with 'prior spec' with one topic per line with format: <topic nr(zero idxed)>, <word1>, <word2>, etc
