The Support Vector Machine instead solves the classification problem by finding the hyper-plane that best separates the data points according to the respective classes. This fact is then used to predict the class associated with a test sample, based on the side of the found plane it is located...
This is one of the two earpieces from my old pair of open-backed headphones with the light foam cover and the cable removed. Note that "open-backed" is a bit of an understatement for what you see here: the headphones are almost completely open to the air and built around a kind of ...
