Abstract
This invention provides a data processing apparatus which can store and recall more complicated time-series data than those processed in related art technologies. In the data processing apparatus, a recurrent neural network (RNN) of higher layer generates long-period parameter and supplies it to an input layer of RNN of lower layer via a computing block. The RNN uses this input as a parameter and computes short-period input.
