I am trying to make sense of the following:
Taken from the MIT website.
So I understand that we want to maximize the distance between the planes H0 and H1, where H0 is defined as
wx+b=0 and H1 is defined as
wx+b=1. I am following with the definition that the distance betweena point
(x0,y0) and a line
What I don't understand is... What is
wx+b? So I understand
w is the weight vector,
x is an input and
b is the offset, so
wx+b gives an indication's of x's class as predicted using the model with weight vector
w. But, when we are looking at the distances between H0 and H1, which are both lines, what 'line' and what 'point' are we referring to?
