示例1: plusEqualsHyperbolicPriorGradient
import cc.mallet.util.Maths; //导入方法依赖的package包/类
public void plusEqualsHyperbolicPriorGradient (Factors other, double slope, double sharpness) {
// TODO This method could use some careful checking over, especially for flipped negations
assert (initialWeights.length == finalWeights.length);
double ss = slope * sharpness;
for (int i = 0; i < initialWeights.length; i++) {
// gsc: checking initial/final weights of crf.parameters as well since we could
// have a state machine where some states have infinite initial and/or final weight
if (!Double.isInfinite(initialWeights[i]) && !Double.isInfinite(other.initialWeights[i]))
initialWeights[i] += ss * Maths.tanh (-other.initialWeights[i]);
if (!Double.isInfinite(finalWeights[i]) && !Double.isInfinite(other.finalWeights[i]))
finalWeights[i] += ss * Maths.tanh (-other.finalWeights[i]);
}
double w, ow;
for (int i = 0; i < weights.length; i++) {
if (weightsFrozen[i]) continue;
// TODO Note that there doesn't seem to be a way to freeze the initialWeights and finalWeights
// TODO Should we also obey FeatureSelection here? No need; it is enforced by the creation of the weights.
if (!Double.isInfinite(defaultWeights[i])) defaultWeights[i] += ss * Maths.tanh(-other.defaultWeights[i]);
for (int j = 0; j < weights[i].numLocations(); j++) {

if (!Double.isInfinite(w)) weights[i].setValueAtLocation(j, w + (ss * Maths.tanh(-ow)));
}
