LM101-052: How to Use the Kernel Trick to Make Hidden Units Disappear

Today, we discuss a simple yet powerful idea which began popular in the machine learning literature in the 1990s which is called "The Kernel Trick". The basic idea of the "Kernel Trick" is that you specify similarity relationships among input patterns rather than a recoding transformation to solve a nonlinear problem with a linear learning machine. It's a great magic trick...check it out at: www.learningmachines101.com where you can obtain transcripts of this episode and download free machine learning software!
