Date:

2007-10-27 The constructor

------------------------------- Parameters ------------------------------- float balance The balance float support The support BinaryMatrix* bm The truth matrix

BSEvaluator::BSEvaluator

(

const BSEvaluator &

src

)

Member Function Documentation

bool BSEvaluator::badBalance

(

)

const [virtual]

Tests to see if the balance is bad, each rowset will need to only appear 0 times

--------------------------------- Return --------------------------------- true: The balance is too low false: The balance is fine

unsigned int BSEvaluator::getMinRowset

(

)

const [virtual]

Gets the minimum rowset size

--------------------------------- Return --------------------------------- The minimum rowset size

unsigned int BSEvaluator::getUpperBound

(

const vector< unsigned int > &

counts

)

const [virtual]

Given a set of rowsets, this determines the upper bound

------------------------------- Parameters ------------------------------- const vector<unsigned int>& counts The rowset sizes

--------------------------------- Return --------------------------------- A the upper bound on the support of the itemset that generated these sizes

Implements Evaluator.

unsigned int BSEvaluator::getUpperBound

(

)

const [virtual]

Gets the largest itemset size possible given the matrix

--------------------------------- Return --------------------------------- The largest itemset size possible

Implements Evaluator.

BSEvaluator & BSEvaluator::operator=

(

const BSEvaluator &

rhs

)

[virtual]

The = operator

------------------------------- Parameters ------------------------------- const BSEvaluator& rhs The right hand side

--------------------------------- Return --------------------------------- A reference to the evaluator

void BSEvaluator::setBinaryMatrix

(

BinaryMatrix *

bm

)

[virtual]

Sets the binary matrix

------------------------------- Parameters ------------------------------- BinaryMatrix* bm The binary matrix

Reimplemented from Evaluator.
