Alex Herbert commented on MATH-1651:
------------------------------------
Or even refactor the extraction of the distances to a method:
{code:java}
final double[] distancesBefore = getDistances(net, dist, features);
final double[] distancesAfter = getDistances(net, dist, features);
private static double[] getDistances(Network net,
DistanceMeasure dist,
double[] features) {
return net.getNeurons()
.stream()
.sorted((a, b) -> Long.compare(a.getIdentifier(),
b.getIdentifier()))
.mapToDouble(n -> dist.applyAsDouble(n.getFeatures(), features))
.toArray();
}
{code}
