1)
zero-center (0-center) the normalized values in the model vectors, and then
precalculate each feature vector element based on the offset, and then
pass the sum to each support vector calculation.
assumption: median is close to the mean.
2)
cache individual values in the input feature vector, have 13000 values
assumption: memory won't be too big
