摘要
精度要求是神经网络硬件实现的一个关键问题。本文提出了一种有限精度的BP高速算法,通过实例验证,该算法适于低精度,且收敛速度快。
The precision required for neural network algorithm is an important question for hardware architects. This paper gives an excellent high speed BP algorithm for feed-forward muitilayerneural network using limited precision calculation. The experimental results show that the algorithmimproves convergence speed with reduced precision bits.
