SVM - Understanding the math - Part 1 - The margin - SVM Tutorial

This is the first article from a series of articles I will be writing about the math behind SVM. There is a lot to talk about and a lot of mathematical backgrounds is often necessary. However, I will try to keep a slow pace and to give in-depth explanations, so that everything is crystal clear, even for beginners. Part 1: What is the goal of the Support Vector Machine (SVM)? Part 2: How to compute the margin?
