He dragged the formula to cell I2 for the second hidden neuron. He set up the in cell K2, taking the hidden neurons as inputs, multiplying them by a second set of weights, and squashing them again.
Arthur opened a blank workbook. He wasn't just typing numbers; he was architecting a digital brain.

Multiply the hidden layer outputs by the output weights and add the output bias. =(N2*$L$2)+(O2*$M$2)+(P2*$N$2)+$O$2 Step 4: Calculate Final Prediction ( Ypredcap Y sub p r e d end-sub
This is where the network calculates a prediction based on inputs. Weighted Sum ( He dragged the formula to cell I2 for
This guide provides a full walkthrough for building a multi-layer perceptron (MLP) to solve a simple non-linear problem, such as the . 1. Structure Your Spreadsheet A basic neural network typically consists of three layers: Input Layer: Two nodes (
: Use the Excel Solver Add-in to automate this. Go to the Data tab and select Solver . He wasn't just typing numbers; he was architecting
We will build one row of calculations for the first training example (0,0). Then copy down.
New Weight = Old Weight - (Learning Rate * Gradient)
Set up your XOR truth table:
