Suppose you are given the following dataset: Example Number X1 X2 Y 1 -1 2 -1 2 -2 -2 +1 3 1 -1 +1 4 -3 1 -1 Perform the Single-Mode Perceptron algorithm on this data. Assume you start with initial weights a = [0,0,0] and learning rate n = 1. Pass through all of the examples in order of their example number. What would be the updated weight vector a after the first iteration?
