Parameters:

dependencies - the set of dependencies

log - the reference log

Method Detail

connectedComponents

public RoleSet connectedComponents(double tau_w)

This method extract the roles, as the connected components, after cutting the edges with weight below the tau_w threshold.

Parameters:

tau_w - the weight threshold

Returns:

the set of roles as the connected components after cutting the edges

extractRoles

public RoleSet extractRoles(double tau_w,
                            double tau_rho)
