"Specifically, I started with a very primitive approach, not relying on the magic of convenient libraries like PyTorch and TensorFlow, but understanding the basic calculations of deep learning (from forward propagation to backpropagation using the chain rule of differentiation) and then implementing a single-layer neuron from scratch using only Math, and then implementing XOR completely from scratch using only Numpy."
