Regional Economic Prediction Model Using Backpropagation Integrated with Bayesian Vector Neural Network in Big Data Analytics

Algorithm 1

Proposed BP Algorithm.

 Algorithm for BP

 Input:

  current step size

  prescribed tolerance

 Delta nodes Vectors

 Local variables:

  maximum factor by which step size is improved

  factor by which step size will reduce if tolerance is not met.

 safety factor so step size is just less than extreme suggested

 if then

 tolOK true

 Else

 tolOKfalse

 end if

 return .
