Class MeanSquaredError

  • All Implemented Interfaces:
    it.unibo.alchemist.loader.export.Extractor 
    
public final class MeanSquaredError<T>
 implements Extractor

    Exports the Mean Squared Error for the concentration of some molecule, given another molecule that carries the correct result. The correct value is extracted from every node, then the provided UnivariateStatistic is applied to get a single, global correct value. Then, the actual value is extracted from every node, its value is compared (subtracted) to the computed correct value, it gets squared, and then logged.
