Target function formulation in Q8
I guess this is pretty basic, but I am unclear on this, so would like some help. As per requiremets of question 8
f(x) = 1 for Y=+1 f(x) = 0 for Y = 1 Is my understanding correct ? if yes, f(x) should be the step function of y*x. I am unable to formulate this in a form such that it is differentiable to use SGD. Can someone help me understand how to do it? Thanks

Or do we just use formula to minimize mean square error
sum ( sq(y1  wx1) + sq(y2  wx2) ...) ?

Re: Target function formulation in Q8
Understood. Thanks Prof Yaser. So in this case we can use the theta(s) as the sigmoid function as explained in the lecture, correct?
