Classes [hide private]
  BestDetector
Determine whether the last value in a sequence is the best one given some criterion.
  StoppingCriterion
Base class for all functors to decide when to stop RFE (or may be general optimization... so it probably will be moved out into some other module
  MultiStopCrit
Stop computation if the latest error drops below a certain threshold.
  FixedErrorThresholdStopCrit
Stop computation if the latest error drops below a certain threshold.
  NStepsStopCrit
Stop computation after a certain number of steps.
  NBackHistoryStopCrit
Stop computation if for a number of steps error was increasing
  ElementSelector
Base class to implement functors to select some elements based on a sequence of values.
  RangeElementSelector
Select elements based on specified range of values
  TailSelector
Select elements from a tail of a distribution.
  FixedNElementTailSelector
Given a sequence, provide set of IDs for a fixed number of to be selected elements.
  FractionTailSelector
Given a sequence, provide Ids for a fraction of elements
