πŸ€ Challenge: Backpropagation - 3 Layered Neural Network

As a challenge, code the backpropagation pass for a 3 layered neural network.

Problem statement

Code the backpropagation operation for the three layered neural network to compute the gradient of the cross-entropy loss function with respect to weights and biases of the neural network.

The cross entropy loss function is as follows:

L(y,s)=βˆ‘i=1cyiβ‹…log(si)\mathcal{L}(y, s) = \sum_{i=1}^{c} y_i \cdot log(s_i) ...
