Uses of NestedCrpNode in org.knowceans.sandbox.hlda

Fields in org.knowceans.sandbox.hlda declared as NestedCrpNode

(package private) NestedCrpNode[][]	HldaGibbsSampler.c c[m][ell] is the restaurant corresponding to the ell'th topic for document m.
(package private) NestedCrpNode	HldaGibbsSampler.ncrp the nested CRP structure into which c points
NestedCrpNode	NestedCrpNode.parent parent restaurant (root = null)

Fields in org.knowceans.sandbox.hlda with type parameters of type NestedCrpNode

private java.util.Vector<NestedCrpNode>

NestedCrpNode.children children = list of occupied tables in the nested CRP

Methods in org.knowceans.sandbox.hlda that return NestedCrpNode

NestedCrpNode	HldaGibbsSampler.getNcrp() Retrieve estimated nested topic structure.
private NestedCrpNode	NestedCrpNode.sampleCrp() returns the child node sampled from the CRP.
protected NestedCrpNode[]	HldaGibbsSampler.sampleCrpFullConditional(int m) Sample a tree path c_m from the full conditional distribution: p(c_m | c_-m, w_-m, z) \propto p(w_m | c, w_-m, z) p(c_m | c_-m), where p(c_m | c_-m) = m_i / (gamma + m - 1) for occupied tables and = gamma / (gamma + m - 1) for unoccupied tables is the CRP prior.
NestedCrpNode[]	NestedCrpNode.sampleHierarchical() given tbe probability assignments in the nodes and the L-vector newprob for new CRP paths, sample a path hierarchically.
NestedCrpNode[]	NestedCrpNode.samplePath() sample once from the nested CRP and update the occupation numbers
NestedCrpNode[]	NestedCrpNode.samplePath(int doc) calculates the word conditionals, which, in conjunction with the CRP prior, yield the path probabilities.
private NestedCrpNode	NestedCrpNode.sampleProb(boolean crp) Sample according to probability assignments in the prob field.

NestedCrpNode.updateCounts(NestedCrpNode[] path, int doc) updates the counts for the current sample.
