Also, since w.0, w.1 and w.2 are different numbers, do you need multiple points to assess the values of the three w's?

Further, is updated w like an array, dependent on which n is being chosen, or is it one uniform number that is applied to all x's?
Indeed, the different points in the training data set are treated one at a time by PLA, independently of the rest of the points.

All three components of the weight vector {\bf w}=w_0,w_1,w_2 are simultaneously updated by PLA at each iteration, and there is more than one data point to update {\bf w} depending on which points are misclassified at a given time as the algorithm runs.
Where everyone thinks alike, no one thinks very much
