Member Function Documentation

void ClusterRep::addTerms (  const vector< int > &    tids )  [inline]

add 1 to each element in the vector specified in tids. Destructively modifies the vector

void ClusterRep::addVal (  int    id, double    val )  [inline]

add val to each element in the vector. Destructively modifies the vector

void ClusterRep::addVec (  const ClusterRep *    v2 )  [inline]

adds vector to rep. Destructively modifies the vector

double ClusterRep::dotProd (  const ClusterRep *    v2 )  const [inline]

computes dot product between two reps.

FloatFreqVector* ClusterRep::getRep (    )  const [inline]

This should not be exposed...

void ClusterRep::normalize (    )  [virtual]

divide each element by the square root of the sum of the squared elements in the vector.

void ClusterRep::subtract (  const ClusterRep *    v2 )  [inline]

subtracts vector from rep. Destructively modifies the vector

double ClusterRep::sum2 (    )  const [inline]

sum of the squared elements in the vector.

void ClusterRep::weigh (  double    val )  [inline]

multiply each element by val. Destructively modifies the vector

void ClusterRep::weigh (  const double *    vals )  [inline]

multiply each element by the corresponding entry in vals. Destructively modifies the vector
