): Delta_O1 = (Prediction - Target) * Prediction * (1 - Prediction) 2. Hidden Layer Gradients Next, pass that error backward to the hidden layer nodes ( H1cap H sub 1 H2cap H sub 2

In Python, you loop 10,000 times. In Excel, you traditionally needed VBA. With the "new" Excel, we use (enabled manually) or a simple Data Table . ): Delta_O1 = (Prediction - Target) * Prediction

This guide produces a working, trainable 1-hidden-layer neural network (input → hidden → output) that you can run, inspect, and train with backpropagation using only Excel formulas and built-in tools (no add-ins). Assumptions and defaults: With the "new" Excel, we use (enabled manually)

Before diving into the steps, let's clarify the scope of our project. We will build a :

Change W1 , W2 , b1 , b2 slightly and watch Loss change.
