PROCESSING DEVICE, PROCESSING METHOD AND PROCESSING PROGRAM

A processing device includes: a first processing unit that refers to function data including a labeling function that labels an input dataset or abstain if it cannot label, to output first output data that associates each input dataset with a probability of corresponding to each label from a result of labeling the input dataset by the labeling function; and an identifying unit that identifies an input dataset in which a variation in the probability of corresponding to each label in the first output data satisfies a predetermined condition among the input datasets. A labeling function newly created for the input dataset identified from the first output data by the identifying unit is inserted into the function data.
