示例1: compare
import gnu.trove.map.TIntFloatMap; //导入方法依赖的package包/类
public double compare(
TIntFloatMap v1,
TIntFloatMap v2,
boolean sorted)
{
//it does not matter if the vectors are sorted or not
double DKL = 0.0;
TIntFloatIterator iter = v1.iterator();
while (iter.hasNext())
{
iter.advance();
int key = iter.key();
if (!v2.containsKey(key))
{
continue;
}
double P = iter.value();
double Q = v2.get(key);
DKL += Math.log(P/Q) * P;
}

示例2: getSortedIndices
import gnu.trove.map.TIntFloatMap; //导入方法依赖的package包/类
public static int[] getSortedIndices(TIntFloatMap vector)
{
// NOTE: it's probably possible to do this using purely primitive
// operations without having to resort to pushing things into an
// Index[]. However, this code is much cleaner to have and since we
// sort at most once per vector and the result is memoized, we don't
// lose too much from the Object-based sorting.
Index[] keyValPairs = new Index[vector.size()];
TIntFloatIterator iter = vector.iterator();
int i = 0;
while (iter.hasNext())
{
iter.advance();
keyValPairs[i++] = new Index(iter.key(), iter.value());
}

int[] sortedIndices = new int[keyValPairs.length];
for (i = 0; i < keyValPairs.length; ++i)

return sortedIndices;
