Excel New: Build Neural Network With Ms

| Current Workarounds | Proposed Feature | | :--- | :--- | | Manual matrix multiplication with MMULT | Automatic forward/backward pass | | Solver add-in for tiny networks | True gradient descent with Adam | | No weight persistence | Save/load network as a formula | | Error-prone manual ReLU/Sigmoid | Built-in, optimized activation functions |

This is the chain rule: δ1 = (δ2 · W2^T) * ReLU_Prime(Z1) ReLU Prime = 1 if Z1 > 0 else 0. build neural network with ms excel new
