maxParents_penalty {exametrika} | R Documentation |
Utility function for searching DAG
Description
Function to limit the number of parent nodes
Usage
maxParents_penalty(vec, testlength, maxParents)
Arguments
vec |
gene Vector corresponding to the upper triangular of the adjacency matrix |
testlength |
test length. In this context it means a number of nodes. |
maxParents |
Upper limit of number of nodes. |
Details
When generating an adjacency matrix using GA, the number of edges coming from a single node should be limited to 2 or 3. This is because if there are too many edges, it becomes difficult to interpret in practical applications. This function works to adjust the sampling of the randomly generated adjacency matrix so that the column sum of the upper triangular elements fits within the set limit.
