The backpropagation algorithm this numerical method was used by different research communities in different contexts, was discovered and rediscovered, until in 1985 it found its way into connectionist ai mainly through the work of the pdp group  it has been one of the most studied and used algorithms for neural. The backpropagation algorithm is based on widrow-hoff delta learning rule in which the weight adjustment is done through mean square error of the output response to the sample input [vel98] the set of these sample patterns are repeatedly presented to the network until the error value is minimized refer to the figure.
The back propagation algorithm has been modified to work with- out any multiplications and to one of the main problems for implementing the backpropagation algorithm in hard- ware is the large number of several researchers have tried to tl'ain networks where the weights are limited to powers of two (kwan and tang.
