Question 1

KnowYourPet is an app utilizing ML to determine whether a pet is hungry or not. It is understood that a dog is likely to be not hungry most of the time, as reflected in the training data. If the dog is mis-diagnosed as hungry then it may lead to overfeeding of the dog and this could lead to serious health issues.Which of the following metrics would you choose for determining the suitability of the model under test?

Options :

A : Accuracy

B : Recall

C : Precision

D : F1-Score

Answer: C

Question 2

A transportation company operates three types of delivery vehicles in its fleet. The vehicles operate at different speeds (slow, medium, and fast). The transportation company is attempting to optimize scheduling and has created an AI-based program to plan routes for its vehicles using records from the medium-speed vehicle traveling to selected destinations. The test team uses this data in metamorphic testing to test the accuracy of the estimated travel times created by the AI route planner with the actual routes and times. Which of the following describes the next phase of metamorphic testing?

Options :

A :

The team tests the time required for the fast and slow vehicles to travel the same route as the medium vehicle. Then, by calculating the speed difference, they then predict how much faster or slower the vehicles will travel. That information is then used to verify that the arrival time of the vehicles meets the expected result.

B :

The team decomposes each route into the relevant components that affect the travel time such as traffic density and vehicle power. The team then uses statistical analysis to characterize the influence of each component to calculate the fast and slow vehicle route times.

C :

The team uses an AI system to select the most dissimilar routes. With this information, any of the AI routes can be metaphorically transformed into a fast or slow route.

D :

The team uses the same AI route planner to create routes that are longer and shorter but follow the same track. Finally, by driving the fast vehicles on the long routes and slow vehicles on the short routes and vice versa, the AI system will have enough information to infer travel times for all vehicles on all routes.

Answer: A
