Public Member Functions

virtual string info () const
 returns a bit more informative string about object (default returns classname())

virtual void init (int inputsize)
 Call this method once with the correct inputsize.

virtual void update (const Vec &input)

void PLearn::StddevStatsIterator::declareOptions OptionList ol  )  [static, protected]
 

redefine this in subclasses: call declareOption(...) for each option, and then call inherited::declareOptions(options) ( see the declareOption function further down)

ex: static void declareOptions(OptionList& ol) { declareOption(ol, "inputsize", &MyObject::inputsize_, OptionBase::buildoption, "the size of the input\n it must be provided"); declareOption(ol, "weights", &MyObject::weights, OptionBase::learntoption, "the learnt model weights"); inherited::declareOptions(ol); }

Reimplemented from PLearn::StatsIterator.

Definition at line 234 of file StatsIterator.cc.

References PLearn::declareOption(), and PLearn::OptionList.

bool PLearn::StddevStatsIterator::finish  )  [virtual]
 

Call this method when all the data has been shown (through update) If the method returns false, then a further pass through the data is required.

Implements PLearn::StatsIterator.
