25. Let a, b, c be three 8-bit operands to a carry-save adder and their values be a = 00010110, b = 01101101 and c = 01001110. What are carry outputs of this carry-save adder? (A) 01001110 (B) 00110101 (C) 01010110 (D) 00111010 (E) 01101101

26. Which of the following activation functions can avoid the vanishing gradient problem? (A) ReLU (B) tanh (C) Sigmoid (D) ELU (E) None of the above

27. What is the status of a process if the process stops because its time slot is over? (A) Waiting (B) Running (C) Ready (D) Sleeping (E) Terminated

28. In machine learning, a confusion matrix is a table that is often used to describe the performance of a classification model on a set of test data for which the true values are known. One can use the matrix to calculate the evaluation metrics, such as accuracy, precision, recall, and F1 score. Suppose a confusion matrix contains TP (true positive) = 900, FN (false negative) = 100, FP (false positive) = 50, and TN (true negative) = 950. What is the value of precision for the model? (A) 1850/2000 (B) 900/1000 (C) 900/2000 (D) 50/950 (E) 900/950

30. For a Generative Adversarial Network (GAN) that can produce images of cars, which of the following statements is TRUE? (1) The generator aims to learn the distribution of car images. (2) After training the GAN, the discriminator loss eventually reaches a constant value. (3) The generator can produce unseen images of cars. (4) The discriminator can be used to classify images as car vs. non-car. (A) (1) and (2) (B) (2) and (3) (C) (1), (2) and (3) (D) (2), (3) and (4) (E) (1), (2), (3) and (4)
