ANN Approach for Weather Prediction using Back Propagation
... For better understanding, the back propagation learning algorithm can be divided into two phases: propagation and weight update. Phase 1: Propagation Each propagation involves the following steps: 1. Forward propagation of a training pattern's input through the neural network in order to generate th ...
