KahanSumAggregator

class KahanSumAggregator extends Aggregator[Float, KahanSum, Float] with Serializable with SynapseMLLogging

Implementation of Kahan summation (https://en.wikipedia.org/wiki/Kahan_summation_algorithm)

Kahan-Babushka-Neumaier sum aggregator make sure lots of small numbers are accumulated numerically stable.
