Machine Learning Demystified, Part 3: Models

In Part 2 of our series, the ML novice realized that generalization is a key ingredient of a true ML algorithm. In today’s post we continue the conversation (the novice is in bold italics) to elaborate on generalization and take a first peek at how one might design an algorithm that generalizes well. Last time we started talking about how one would design an ML algorithm to predict the click-through-rate (CTR) on an ad impression, and you designed two extreme types of algorithms. The first one was the constant algorithm, which simply records the overall historical click-rate a, and predicts a for every new ad opportunity. This was fine for overall accuracy but would do poorly on individual ad impressions, because its predictions are not differentiated based on the attributes…
