In this problem, we will try to understand the convergence of perceptron algorithm and its relation to the ordering of the training samples for the following simple example. Consider a set of n = d labeled d-dimensional feature vectors, {(x(t), y(t)), t = 1,..., d} defined as follows: (t) cos (nt) if it (4.7) (t) (4.8) 0 otherwise, = Recall the no-offset perceptron algorithm, and assume that . x = 0 is treated as a mistake, regardless of label. Assume that in all of the following problems, we initialize 0 = 0 and when we refer to the perceptron algorithm we only consider the no-offset variant of it. Working out Perceptron Algorithm 3 points possible (graded) Consider the d = 2 case. Let y(¹) = 1, y(²) = 1. Assume that the feature vector (¹) is presented to the perceptron algorithm before x(2). For this particular assignment of labels, work out the perceptron algorithm until convergence. Let Ô be the resulting value after convergence. Note that for d = 2, Ô would be a two-dimensional vector. Let's denote the first and second components of by ₁ and 2 respectively.
