Member Function Documentation

virtual HoldoutCrossVal* clone (   )  const [inline, virtual]

Create a new object by replicating itself. Returns: A pointer to the new copy. The code for a derived class Derived is always return new Derived(*this); Though seemingly redundant, it helps to copy an object without knowing the real type of the object. See also: C++ FAQ Lite 20.6 Implements CrossVal. Definition at line 125 of file crossval.h. References HoldoutCrossVal::HoldoutCrossVal().

virtual HoldoutCrossVal* create (   )  const [inline, virtual]

Create a new object using the default constructor. The code for a derived class Derived is always return new Derived(); Implements CrossVal. Definition at line 124 of file crossval.h. References HoldoutCrossVal::HoldoutCrossVal().

std::vector< REAL > cv_round (   )  const [protected, virtual]

one round of the cross-validation operation Implements CrossVal. Definition at line 203 of file crossval.cpp. References dataset::append(), HoldoutCrossVal::p_test, LearnModel::ptd, and randu.

REAL holdout (   )  const [inline]

Definition at line 128 of file crossval.h. References HoldoutCrossVal::p_test.

virtual const id_t& id (   )  const [virtual]

Returns: Class ID string (class name) Implements Object.

bool serialize (  std::ostream &  , ver_list &  )  const [protected, virtual]

Reimplemented from CrossVal. Definition at line 190 of file crossval.cpp. References HoldoutCrossVal::p_test, and SERIALIZE_PARENT.

void set_holdout (  REAL  p, UINT  r = 0 )  [inline]

set the holdout portion and optionally set the number of rounds Definition at line 130 of file crossval.h. References HoldoutCrossVal::p_test, and CrossVal::set_rounds(). Referenced by HoldoutCrossVal::HoldoutCrossVal().

bool unserialize (  std::istream &  , ver_list &  , const id_t &  = NIL_ID )  [protected, virtual]

Reimplemented from CrossVal. Definition at line 196 of file crossval.cpp. References Object::NIL_ID, HoldoutCrossVal::p_test, and UNSERIALIZE_PARENT.
