Adding to will indeed achieve that, since it will add to the quantity and what it adds agrees with in sign since the part is always positive.

Earlier I indicated having difficulty with reading the equations in problem 1.3.
It works but I'm concerned I'm updating weights with a rule that is "not so smart":
 the difference between the target function value and x2 (or the yvalue in a visual simulation) for a misclassified point.
Especially I don't recognize the product of "x transpose and x" part.
To summarize my questions:
 would insight into vector computation make 'everything easier'?
 what is p in the equation? A random symbol?
Thanks again.
