sub.crf {CRF} | R Documentation |
Generate sub CRF by selecting some nodes
sub.crf(crf, subset)
crf |
The CRF generated by |
subset |
The vector of selected node ids |
The function will generate a new CRF from a given CRF
by selecting some nodes. The vector subset
contains the
node ids selected to generate the new CRF. Unlike
clamp.crf
, the potentials of remainning nodes and edges are
untouched.
The function will return a new CRF with additional components:
original |
The original CRF data. |
node.id |
The vector of the original node ids for nodes in the new CRF. |
node.map |
The vector of the new node ids for nodes in the original CRF. |
edge.id |
The vector of the original edge ids for edges in the new CRF. |
edge.map |
The vector of the new edge ids for edges in the original CRF. |
