1. A classifying device comprising: a processing unit; and a memory storing instructions in modules that when executed by the processing unit cause the classifying device to carry out a method comprising: adaptively classifying data values using a correntropy loss function, wherein adaptively classifying the data values comprises, in response to classifying a data value, calculating, based at least in part on the correntropy loss function, a correntopy statistical similarity between a predicted label for the data value determined by the classifying the data value and an actual label for the data value; and adjusting at least one weight of a plurality of weights of the classifying device based at least in part on the correntropy statistical similarity.
