The data processing apparatus includes a data extraction unit which extracts a candidate of teacher data, from time series data, a teacher data creation unit which creates the teacher data based on a label to classify the candidate of teacher data, and the candidate of teacher data which are labeled, and a teacher data complement unit which further extracts the candidate of the teacher data from the time series data that exists between a specific candidate of the teacher data at a specific timing and one of other candidates of the teacher data at a timing different from the specific timing, based on a degree of a variation between these candidates of the teacher data.
