Using vector dot-product form, with x0=1:
for D real numbers, f: RD → {+1, 0}
Engr Dr S Talha Ahsan
Alternatively, we say that classifier h is the result of
passing the linear function through a threshold
function:
hW(x) = Threshold(w ⋅ x)
where Threshold(z) = 1 if z ≥ 0
0 otherwise.
z = w.x
12
w.x = [w0 w1 w2] [ 1
x1
x2 ]
= -4.9 + 1.7x1 –x2
