| 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
