Linear Classifier and Threshold Function Quiz

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 ]
