1. Consider the following classification problem. The data is characterized by two features x and x2 with the classification shown in the figure below (Co are green circles, C1are red x's). Describe how you can use a linear discriminant to classify new examples (give a specific classifier, including weight vector). See Example 2 in the Linear Discriminants lecture for an idea of what to do. (Hint: the equation of the dotted curve is x2 (x1)2). Once you have created a classifier, demonstrate how you use it to classify the new points (-1, 2) and (1.5, 1) 6 xX 3 1. Consider the following classification problem.
