Deep learning is often seen as a black box. We know that it learns from data, but we rarely stop to ask how it truly learns.
What if we could open that box and watch each step happen right before our eyes?
With Excel, we can do exactly that, see how numbers turn into patterns, and how simple calculations become the foundation of what we call “deep learning.”
In this article, we will build a tiny Convolutional Neural Network (CNN) directly in Excel to understand, step by step, how machines detect shapes, patterns, and meaning in images.
