Training Back-Propagation Neural Networks (BPNNs) on big datasets faces two challenges, the hight time cost and possibility of getting trapped into local optimum. MapReduce has been introduced to improve efficiency BPNN training in recent years. After each turn split dataset concurrently, lots BPNNs that are only convergent specific will be produced, a global candidate whole needs generated from them. This process is full challenges because it high impact as well accuracy. The paper...

Owing to its scalability and high fault-tolerance even on a distributed environment built up with personal computers, MapReduce has been introduced parallelise the training of Back Propagation Neural Networks (BPNNs) high-dimensional big datasets. Based evolution local BPNNs produced by Map tasks different data splits, paper proposes novel approach data-parallel in MapReduce. The provides reasonable measure get global convergent BPNN candidates from only specific splits. Further, it not can...
