Sets parameters used during the data indexing.- Specified by:
initin interfaceDataIndexer- Parameters:
indexingParameters- TheTrainingParametersto be used.reportMap- TheMapused for reporting.
-
getContexts
public int[][] getContexts()- Specified by:
getContextsin interfaceDataIndexer- Returns:
- Retrieves a 2-dimensional array whose first dimension is the event index and array this refers to contains the contexts for that event.
-
getNumTimesEventsSeen
public int[] getNumTimesEventsSeen()- Specified by:
getNumTimesEventsSeenin interfaceDataIndexer- Returns:
- Retrieves an array indexed by the event index indicating the number of times a particular event was seen.
-
getOutcomeList
public int[] getOutcomeList()- Specified by:
getOutcomeListin interfaceDataIndexer- Returns:
- Retrieves an array indicating the outcome index for each event.
-
getPredLabels
- Specified by:
getPredLabelsin interfaceDataIndexer- Returns:
- Retrieves an array of predicate/context names indexed by context index.
These indices are the value of the array returned by
DataIndexer.getContexts().
-
getOutcomeLabels
- Specified by:
getOutcomeLabelsin interfaceDataIndexer- Returns:
- Retrieves an array of outcome names indexed by outcome index.
-
getPredCounts
public int[] getPredCounts()- Specified by:
getPredCountsin interfaceDataIndexer- Returns:
- Retrieves an array of the count of each predicate in the events.
-
getNumEvents
public int getNumEvents()- Specified by:
getNumEventsin interfaceDataIndexer- Returns:
- Retrieves the number of total events indexed.
-
getValues
public float[][] getValues()- Specified by:
getValuesin interfaceDataIndexer- Returns:
- Retrieves the values associated with each event context or
nullif integer values are to be used.
