Question 1 (20 points) Consider a two-dimensional classification problem with two classes whose a priori probabilities are $P(\omega_1) = 0.75$ and $P(\omega_2) = 0.25$. The two classes follow Gaussian distributions, that is, $p(x|\omega_1) = N(\mu_1, \Sigma_1)$ and $p(x|\omega_2) = N(\mu_2, \Sigma_2)$ where $\mu_1 = \begin{bmatrix} 0 \ 0 \end{bmatrix}$, $\Sigma_1 = \begin{bmatrix} 2 & 0 \ 0 & 2 \end{bmatrix}$, $\mu_2 = \begin{bmatrix} 1 \ 1 \end{bmatrix}$, $\Sigma_2 = \begin{bmatrix} 1 & 0 \ 0 & 1 \end{bmatrix}$. 1. Design a Bayesian classifier that minimizes the error probability. 2. Design a Bayesian classifier that minimizes the average risk with the loss matrix $\Lambda = \begin{bmatrix} \lambda_{11} & \lambda_{12} \\ \lambda_{21} & \lambda_{22} \end{bmatrix} = \begin{bmatrix} 0 & 2 \ 1 & 0 \end{bmatrix}$

a) The two most common types of stepper motors are permanent magnet and variable reluctance. In the absence of a label on the motor, state two tests which would allow either stepper motor type to be distinguished from each other. b) Figure 2.1 shows a MOSFET drive circuit for one phase of a unipolar stepper motor where the supply voltage Vs = 12V; Phase resistance R = 70Ω; Phase inductance L = 56mH: I. What is the function of the diode in this circuit? II. How long does it take to establish the rated current of 0.19Amps in the motor coil once the MOSFET switch is turned on? III. What is the drawback of running the motor at a speed such that it cannot attain the rated winding current due to the L/R time constant of the coil? IV. What drive circuit is required to drive a bipolar stepper motor? Figure 2.1 MOSFET drive circuit for one phase of a unipolar stepper motor Phase Winding of a unipolar stepper motor Gate Drive Controller
