You no longer need to set up a Python environment to explain Gradient Descent to a business stakeholder. You can open Excel, show them the weights changing cell by cell, and prove that the network is "learning."
In cell M6 : =(I6# - K6) * (I6# * (1 - I6#)) 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
In the modern era of artificial intelligence, it seems like you need a PhD in mathematics, a powerful GPU cluster, and fluency in Python (TensorFlow or PyTorch) to build a neural network. However, a quiet revolution has occurred. You can now build a fully functional, learning neural network using the "new" dynamic array features of Microsoft Excel. You no longer need to set up a
Forget the old days of clunky VBA macros or manual matrix multiplication. With Excel’s and modern LAMBDA functions , you can build a Forward Propagation and Backpropagation engine from scratch inside a spreadsheet. However, a quiet revolution has occurred
