Claim 0:
1. A traffic fluctuation prediction apparatus, comprising:
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
divide time-series data of traffic into two data sets;
learn a dictionary Dr(t) using one of the two divided data sets, and learn a dictionary Dp(t) using the other of the two divided data sets;
obtain a sparse code YN(t) in representing the time-series data using the dictionary Dr(t), and obtain a predicted value XN{circumflex over ( )}(t) of future traffic using the obtained sparse code YN(t) and the dictionary Dp(t); and
using a search for a stable region of a double queue of overestimation and underestimation, a prediction error of the predicted value XN{circumflex over ( )}(t).
