203.5.7 The Neural Network Algorithm

In previous section, we studied about Neural Network Intuition

In all previous posts we progressed to this part. We will breakdown the steps how a neural network starts and ends.

The Neural Network Algorithm

  • Step 1: Initialization of weights: Randomly select some weights .
  • Step 2 : Training & Activation: Input the training values and perform the calculations forward.
  • Step 3 : Error Calculation: Calculate the error at the outputs. Use the output error to calculate error fractions at each hidden layer
  • Step 4: Weight training: Update the weights to reduce the error, recalculate and repeat the process of training & updating the weights for all the examples.
  • Step 5: Stopping criteria: Stop the training and weights updating process when the minimum error criteria is met.
