While no one would use Excel for production AI, this exercise turns a "black box" neural network into a transparent, cell-by-cell calculation. You can now extend this to 3 hidden layers, ReLU activation functions, or even a regression task. The only limit is your row count and patience. | A | B | C | |
Introduction: Why Excel? When you hear "Neural Network," you typically think of Python, TensorFlow, or PyTorch. But beneath all those high-level libraries lies pure mathematics: linear algebra, calculus, and iterative optimization. Microsoft Excel, despite being a spreadsheet tool, is surprisingly capable of executing these operations manually. You can now extend this to 3 hidden
