ABSTRACT:
A parallel data processing system uses a parallel learning method capable of having sufficient parallelness to shorten learning time and has plural data processing units, each connected to a data transfer unit and having a unit for holding execution parameters as are required for data processing, a unit for holding partial sample data which comprises at least part of the full sample data necessary for the required data processing, an adjustment value calculation unit which calculates, from partial sample data stored in the unit for holding partial sample data and from the execution parameters held in the execution parameter holding unit, adjustment amounts related to the execution parameters with regard to the partial sample data and, further, an accumulator which, when calculating the overall total of the execution parameter adjustment amounts with regard to the full sample data, accumulates the adjustment amounts related to the execution parameters with regard to the partial sample data at the data processing units and the adjustment amounts related to the execution parameters with regard to the partial sample data at other data processing units by the data transfer unit.
