Examples of org.apache.hama.ml.math.DoubleVector.dot()

org.apache.hama.ml.math.DoubleVector.dot()
Calculates the dot product between this vector and the given vector. @param s the given vector s. @return the dot product as a double.


    double errorInstance = 0;
    for (DoubleVector vector : vecInstanceList) {
      DoubleVector decoded = encoder.getOutput(vector);
      DoubleVector diff = vector.subtract(decoded);
      double error = diff.dot(diff);
      if (error > 0.1) {
        ++errorInstance;
      }
    }
    Log.info(String.format("Autoecoder error rate: %f%%\n", errorInstance * 100 / vecInstanceList.size()));
