Class MCCluster

One found cluster as a result of MCluster-Miner data-mining task
inherits from LMWrap
namespace: lm.tasks.results

Constructor

No constructor available. Objects of this class could not be instantiated from Lua scripts.

Properties List

CenterVectorSize	Size of center-vector (same as the number of attributes used for clustering)
ClassCategory	the most frequent category in this cluster or nil if no class attribute has been provided in task setting
ClassFrequency	Number of objects belonging to the most frequent class or zero if no class attribute provided in task setting
ClusterIndex	Index of this cluster among clusters on the same level
ClusterLevel	Level of this cluster (for hierarchical clustering)
Frequency	Number of objects in this cluster
HypothesisMC	the HypothesisMC, this cluster belongs to
ID	Unique identifier (primary key) of the object
IntraDistanceAvg	Average intra-cluster distance
IntraDistanceMax	Maximal intra-cluster distance
IntraDistanceMin	Minimal intra-cluster distance
LeafFlag	Whether this cluster is a leaf (has no childrens)
LevelIndexString	Text representation of this cluster using levels and indexes
MCParentCluster	the parent cluster for this cluster or nil if this cluster is the top-most
TopMostFlag	Whether this cluster is the top most (has no parents)

Methods List

canDel ()	Returns true if the object could be deleted (is not used)
getCenterVector ()	Returns array of floats representing the center of this cluster. The size of the array is equal to number of attributes used for clustering in this hypothesis.
getCenterVectorSize ()	Returns size of vector of center values, the value of CenterVectorSize property
getClassCategory ()	Returns the most frequent category in this cluster or nil if no class attribute has been provided in task setting. the value of ClassCategory property
getHypothesisMC ()	Returns the HypothesisMC, the hypothesis this cluster belongs to, the value of HypothesisMC property
getID ()	Returns unique identifier (primary key) of the object
getMCParentCluster ()	Returns the parent cluster of this cluster (optional). the value of MCParentCluster property
onAdd ()	Store the newly created object into metabase
onDel ()	Delete the object from metabase (fails if canDel returns false)
onUpdate ()	Save changes made to the object into metabase
