Question 1

What is the correction definition for the term “annotation”?

A : type of bias caused by the ML algorithm

B : type of specialized hardware designed to accelerate AI applications

C : activity of identifying objects in images with bounding boxes to provide labelled data for classification.

D : oftware licensing and delivery model in which AI and AI development services are centrally hosted.

Answer: C

Question 2

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?

A : curacy

B : call

C : ecision

D : -Score

Answer: C

Question 3

Consider a machine learning model where the model is attempting to predict if a patient is at risk for stroke. The model collects information on each patient regarding their blood pressure, red blood cell count, smoking, status, history of heart disease, cholesterol level, and demographics. Then, using a decision tree the model predicts whether or not the associated patient is likely to have a stroke in the near future. One the model is created using a training data set, it is used to predict a stroke in 80 additional patients. The table below shows a confusion matrix on whether or not the model mode a correct or incorrect prediction. The testers have calculated what they believe to be an appropriate functional performance metric for the model. They calculated a value of 2/3 or 0.6667.

A : F1 –source

B : Precision

C : Recall

D : Accuracy

Answer: D

Question 4

Which ONE of the most following statements is NOT true about system testing?

A : may take the form of field trials in the expected operational environment or testing within a simulator

B : is a test level in which many of the non-functional requirements for the system are tested

C : The ML functional performance criteria are re-tested to ensure that the test results from the initial ML model testing are not adversely affected when the model is embedded within a complete system during the testing

D : tests that the inputs from the data pipeline are received as expected by the model, and that any predictions produced by the model are exchanged with the relevant system components for effective use

Answer: D

Question 5

What is the correct definition of the term "artificial intelligence (AI)"?

A : measure of how well a classifier can distinguish between two classes

B : activity of identifying objects in images with bounding boxes to provide labelled data for classification

C : type of specialized hardware designed to accelerate AI applications

D : capability of an engineered system to acquire, process, create and apply knowledge and skills

Answer: D
