Class PerformanceMeasuresNode

java.lang.Object
edu.tufts.hrilab.action.db.performanceMeasures.PerformanceMeasuresNode
public class PerformanceMeasuresNode extends Object
Tree to keep track of the probability an action will succeed and the expect time given arguments Using tree instead of table for easier lookup of queries using unbound args

    • updatePerformanceModels

      public void updatePerformanceModels(List<Symbol> argValues, boolean isSuccess, double time)
      incremental update of experience and time distribution
      Parameters:
      argValues - input values to action parameters, used to find correct performance node
      isSuccess - did the effect hold / did the action succeed
      time - time to complete the action

      public void updateEffectPerformanceModels(Map<Predicate,Boolean> effectHolds, List<Symbol> argValues)
      incremental update of effect models
      Parameters:
      effectHolds - map from effect predicate to boolean value
      argValues - input vaules to aciton parameters, used to update correct performance node

      batch update of time distribution (reading performance measures from file)
      Parameters:
      argValues - input values to action parameters, used to find correct performance node
      experience - total number of times action has been executed
      holds - number of times the effect hold / did the action succeed
      successTimeMean - mean time to complete the action with specified args
