If you are using or Excel 2021 , you can bypass Solver and create an interactive training loop using native formulas and a designated learning rate ( , e.g., 0.1 ).
Tip: Fill these cells with temporary values like 0.5 , -0.2 , 0.1 , etc. Do not use all zeros, or the network will fail to learn. Step 2: Forward Propagation (The Math)
Absolutely not.
To introduce non-linearity, apply the ReLU function, which keeps positive values and sets negative values to zero. Use this formula: =MAX(0, Weighted_Sum) . Step 2: Calculate Output Layer
Training means updating the weights and biases using Gradient Descent:
=D5 - $Learning_Rate * (Gradient_Output * Hidden_1)
You can now write these formulas in Excel, referencing the weight, bias, and input cells. For the Sigmoid function, use the built‑in EXP() function.
