f(x,w,b) = sign(w. x - b)<br />
Define the margin<br />
of a linear<br />
classifier as the<br />
width that the<br />
boundary could be<br />
increased by<br />
before hitting a<br />
datapoint.<br />

Linear SVM<br />
f(x,w,b) = sign(w. x - b)<br />
<strong>The</strong> maximum<br />
margin linear<br />
classifier is the<br />
linear classifier<br />
with the, um,<br />
maximum margin.<br />
This is the<br />
simplest kind of<br />
SVM (Called an<br />
LSVM)<br />
