Class HypothesisET

Decision/exploration tree as a result of a ETree-Miner data-mining task
inherits from Hypothesis
namespace: lm.tasks.results

Constructor

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

Properties List

FrequencyClass  number of objects with the most frequent class in each leaf
FrequencyTotal  Number of objects this hypothesis covers
ID  Unique identifier (primary key) of the object
Order  Order-index of this hypothesis
Quality  Quality of the tree as a ratio of FrequencyClass to FrequencyTotal
Task  the Task, this hypothesis belongs to
Text  Textual representation of this hypothesis
TextHTML  HTML representation of this hypothesis
Weight  Property used for storing eg. primary interest measure value for LM ReverseMiner

Methods List

createDerivedDataColumn () Creates a new derived DataColumn with values representing class indexes based on this hypothesis decision tree results (i.e. the value for each row will be the zero-based index of the class category this row was classified into)
getFrequencyClass () Returns the value of FrequencyClass property
getFrequencyTotal () Returns the value of FrequencyTotal property
getID () Returns unique identifier (primary key) of the object
getOrder () Returns the value of Order property
getQuality () Returns the value of Quality property
getTask () Returns the Task this hypothesis belongs to, the value of Task property
getWeight () Returns the value of Weight property
checkMutualInfluence () Returns a type of relationship between hypothesis and given mutual influence, see HypothesisMutualInfluenceRelationship codes
prepareFTPartialCedentArray () Returns array of FTPartialCedents, partial cedents of a given type in this hypothesis
setOrder () Sets the value of Order property
setWeight () Sets the value of Weight property
