List of valueSparse() Examples

Examples of valueSparse()

weka.core.Instance.valueSparse()
Returns an instance's attribute value in internal format. Does exactly the same thing as value() if applied to an Instance. @param indexOfIndex the index of the attribute's index @return the specified value as a double (If the correspondingattribute is nominal (or a string) then it returns the value's index as a double).

      if (m_KernelIsLinear) {

  for (int p1 = 0; p1 < inst1.numValues(); p1++) {
    if (inst1.index(p1) != m_data.classIndex()) {
      m_weights[inst1.index(p1)] += 
        y1 * (a1 - alph1) * inst1.valueSparse(p1);
    }
  }
  Instance inst2 = m_data.instance(i2);
  for (int p2 = 0; p2 < inst2.numValues(); p2++) {
    if (inst2.index(p2) != m_data.classIndex()) {
