the number of classes for attribute attributeIndex

getVotes

double[] getVotes(int outputAttributeIndex)

The votes for a given output attribute

Returns:

the votes for a given output attribute outputAttributeIndex.

getVote

double getVote(int outputAttributeIndex,
               int classIndex)

The vote assigned to a class of an output attribute

Returns:

the vote for an output attribute outputAttributeIndex and a class classIndex.

setVotes

void setVotes(int outputAttributeIndex,
              double[] votes)

Sets the votes for a given output attribute

setVotes

void setVotes(double[] votes)

setVote

void setVote(int outputAttributeIndex,
             int classIndex,
             double vote)

Sets the vote for class of a given output attribute

getVotes

double[] getVotes()

The votes for the first output attribute

Returns:

the votes for the first output attribute outputAttributeIndex.

hasVotesForAttribute

boolean hasVotesForAttribute(int outputAttributeIndex)

Checks if there are votes for a given output attribute

Returns:

the votes for the first output attribute outputAttributeIndex.

size

int size()
