Question

A neural network has been designed and created to assist day-traders improve efficiency when buying and selling commodities in a rapidly changing market. Suppose the test team executes a test on the neural network where each neuron is examined. For this network the shortest path indicates a buy, and it will only occur when the one-day predicted value of the commodity is greater than the spot price by 0.75%. The neurons are stimulated by entering commodity prices and testers verify that they activate only when the future value exceeds the spot price by at least 0.75%. Which of the following statements BEST explains the type of coverage being tested on the neural network?

Options

  • AThreshold coverage
  • BNeuron coverage
  • CSign-change coverage
  • DValue-change coverage
