It's another exciting week at RapidMiner and today Gandalf the Gray comes to the Cambridge office for Modern Analytics Platform training. That makes Ingo wonder if there is a connection between Lord of the Rings and Support Vector Machines (SVMs). Sure enough, he finds one by comparing the idea of large margin methods with the scene where the fellowship flees from Moria by crossing the bridge of Khazad-dûm.
As you will see, the fellowship doesn't take the risk of balancing on the edge of the bridge but keep enough safety space by running right down the middle.
Ingo explains this basic idea of overfitting control and develops the main formulas of SVMs with the support of Graeme's usual helpful questions and Gandalf's lovely magic.
It turns out that SVMs are "so very magical" at helping to avoid overfitting, are very efficient with respect to runtime, and can even solve non-linear classification and regression tasks by using kernel functions.
Also, Data Scientist #7 and Gandalf "horse around" at the office, Ingo joins their after hours dance party, Marla makes a brief appearance and math makes everyone happy.
For more information on SVMs, you can check out Ingo's SVM Deep Dive Lecture (http://youtu.be/woEwY0Zi6X4) where he explains all the underlying concepts and formulas in 11 minutes – not bad!
As for RapidMiner? It is the One Platform To Rule Them All.
