Question 1

Biases introduce the chance of getting unwanted output from ML systems. Testing for biases allows the identification of errors and causal defects that can further help review datasets and remove unwanted biases.

Which ONE among the following options is not a bias in AI based systems?

A : Algorithmic bias

B : Sample bias

C : Autonomous bias

D : Inappropriate bias

Answer: C

Question 2

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?

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 3

Which of the following options is an open-source ML library operated by Facebook and used for apps applying image processing and natural language processing (NLP)?

A : IBM Watson Studio

B : Apache MxNe

C : Keras

D : PyTorch

Answer: D

Question 4

It is possible to use an AI-assisted test automation tool to recognize objects through image processing, rather than using references to their location.

To which type of AI software engineering technology is this example MOST likely referring?

A : Probabilistic Software Engineering

B : Clustering

C : Search-based Software Engineering

D : Classification, Learning and Prediction

Answer: D

Question 5

What is the correct definition for the term "classifier"?

A : A type of ML function that predicts the output class for a given input

B : A type of ML function that groups similar data points together

C : An ML model used for classification Synonym: classification model

D : The ability of a system to work for sustained periods without human intervention
