An economist predicts consumer choice between banana (1), apple (2), and cheese (3) using two input features through the above artificial neural network. Based on the above figure, if the output of the softmax function for each class in the output layer are, 0.1 for banana, 0.2 for apple, and 0.7 for cheese, the consumer will purchase (1)____________ (a. banana, b. apple c. cheese; 2 points). This example is a case of (2) ___________ (a. regression, b. binary classification, c. multi-class classification; 2 points). Here, the output of the softmax function in the output layer is the probability of y, where y

44. The nurse is caring for a patient admitted with the early stages of septic shock. The nurse assesses the patient to be tachypneic, with a respiratory rate of 32 breaths/min. Arterial blood gas values assessed on admission are pH 7.50, CO2 28 mm Hg, HCO3 26. Which diagnostic study result reviewed by the nurse indicates progression of the shock state?
