00:06 demo a prebuilt version of the application
01:37 code the application
01:49 go over the training data used in this app.
02:47 go over the various classes that make up the app.
03:26 quick introduction to Support Vector Machine (SVM)
04:58 quick introduction to Sequential Minimal Optimization (SMO)
06:02 code the SupportVectorMachines class
