priors: Constructor for prior object

In MansMeg/PerspectiveTopicModel: Samples a perspetice topic model

Description

Constructor for prior object

Usage

priors(
  x = NULL,
  alpha = 0.1,
  betax0 = 0.01,
  betax1 = 0.01,
  alpha_pi = 0.1,
  beta_pi = 0.1,
  non_zero_type_topics = NULL,
  non_zero_doc_topics = NULL,
  perspective_topics = NULL,
  annealing_iterations = NULL
)

Arguments

x	NULL or a list with priors to set
alpha	The alpha parameter
betax0	The betax0 parameter
betax1	The betax1 parameter
alpha_pi	The alpha_pi parameter (prior weight on perspective)
beta_pi	The beta_pi parameter (prior weight on non-perspective)
non_zero_type_topics	List of priors on wordtypes. See details.
non_zero_doc_topics	List of priors on documents. See details.
perspective_topics	Topics that contain perspectives. If NULL, all topics have perspectives. If 0, no topic has perspectives.
annealing_iterations	If simulated annealing is used. Indicate at which iteration the same position in hyper-parameter prior vector that should be used.

Details

The parameter non_zero_type_topics is a list named with types with prior settings. Each element is a type that contains a vector of non_zero probability topics. The parameter non_zero_doc_topics List of priors on documents. See details.

Value

A priors object
