infer.cutset {CRF} | R Documentation |
Computing the partition function and marginal probabilities
infer.cutset(crf, cutset, engine = "default")
crf |
The CRF |
cutset |
A vector of nodes in the cutset |
engine |
The underlying engine for cutset decoding, possible values are "default", "none", "exact", "chain", and "tree". |
Exact inference for graphs with a small cutset using cutset conditioning
This function will return a list with components:
node.bel |
Node belief. It is a matrix with |
edge.bel |
Edge belief. It is a list of matrices. The size of list is |
logZ |
The logarithmic value of CRF normalization factor Z. |
