Options :

A : IBM Watson Studio

B : Apache MxNe

C : Keras

D : PyTorch

Answer: D

Question 2

Al systems like any other conventional system are created with a specific purpose. Testers make it possible to define the system requirement and validate the design specifications.Which ONE of the following is NOT a reason why AL the specification of AL based systems is challenging

Options :

A : The specification of the required logic from the start of the Al-based systems project

B : Poorly specified behavior requirements where the system goals call for replicating human behavior, rather than providing specific functionality

C : The acceptance of tolerances for some of the expected quality requirements

D : The accuracy of the AI-based system is often unknown until the test results from independent testing are available

Answer: A

Question 3

“The process of testing hyperparameters to achieve optimum performance”

Options :

A : ML Model Training

B : Logistic regression

C : ML Model Tuning

D : ML Model Evaluation

Answer: C

Question 4

Given the following descriptions:

I. Model performance is checked using validation data

II. The origin of test data used to test the model is identified

III. The tuned model is made ready for its target hardware

IV. Test data are used to ensure the agreed ML functional performance criteria are met

V. The model is created from source code

VI. The critical data features are identified

Which of the following options BEST matches the descriptions with the activities in the ML workflow?

Options :

A : V - Build & Compile Model / II - Prepare the Data / I - Evaluate the Model

B : III - Build & Compile Model / VI - Prepare the Data / I - Evaluate the Model

C : III - Build & Compile Model / II - Prepare the Data / IV - Evaluate the Model

D : V - Build & Compile Model / VI - Prepare the Data / IV - Evaluate the Model

Answer: A

Question 5

Which ONE among the following statements is FALSE?

Options :

A : The AUC for the ROC curve may be used for supervised classification problems.

B : There are no difficulties with establishing the relative efficacy of each new technology

C : Mean Square Error (MSE) is the average of the squared differences between the actual value and the predicted value

D : The receiver operating characteristic (ROC) curve is a graphical plot that illustrates the ability of a binary classifier as its discrimination threshold is varied
