The Machine Learning and Deep Learning “Advent Calendar” Series: The Blueprint

An upcoming article series will demonstrate how to build machine learning and deep learning models from the ground up using only Excel. The purpose is to open the "black box" of algorithms that are often simplified by programming libraries, making the underlying mechanics transparent. By showing every calculation, the series aims to provide an intuitive understanding for students, developers, and managers alike. The models will be organized by their theoretical approaches, such as distance-based, tree-based, and mathematical functions, to clarify their inner workings and relationships. This approach helps to explain feature importance, model training, and the connections between different algorithms.
