Day #66 - Maths behind backpropagation

Today it's mathematical learning for neural network fundamentals.
Keynotes
  • In Neural Network, Network forward propagates activation to produce output and it back propagates error to determine weight changes
  • Partial Derivative - Derivative of one of the variables holding the rest constant
  • Backpropagation uses gradient descent method, one needs to calculate the derivative of squared error function with respect to the weights of the network.
Happy Learning!!!
