In the previous part of our blog series, we discussed how to initialize a
neural network (NN) model with specified layers and hidden units. Now, in this
part, we will explore the forward propagation algorithm, a fundamental step in
the NN's prediction process.


Before we delve into the coding aspect, let's understand the mathematical

concepts underlying forward propagation. We will use the following notations:



  • Z[l]: Logit Matrix for layer l. It represents the

    linear transformation of the …
