Claim 2:
3. A non-transitory computer-readable medium having computer-executable instructions that, upon execution of the instructions by a processor of a computer, cause the computer to execute:
dividing, by a data division unit, time-series data of traffic into two data sets;
learning, by a learning unit, a dictionary Dr(t) using one of the two divided data sets, and learning, by the learning unit, a dictionary Dp(t) using the other of the two divided data sets;
obtaining, by a prediction unit, a sparse code YN(t) in representing the time-series data using the dictionary Dr(t) learned in the learning unit, and obtaining, by the prediction unit, a predicted value XN{circumflex over ( )}(t) of future traffic using the obtained sparse code YN(t) and the dictionary Dp(t) learned in the learning unit; and
correcting, by a prediction correction unit, a prediction error of the predicted value XN{circumflex over ( )}(t) through search for a stable region of a double queue of overestimation and underestimation.
