Questions # 21:

An airline has created an ML model to project fuel requirements for future flights. The model imports weather data such as wind speeds and temperatures, calculates flight routes based on historical routings from air traffic control, and estimates loads from average passenger and baggage weights. The model performed within an acceptable standard for the airline throughout the summer but as winter set in, the load weights became less accurate. After some exploratory data analysis, it became apparent that luggage weights were higher in the winter than in summer.

Which of the following statements BEST describes the problem and how it could have been prevented?

Options:

A.

The model suffers from drift and therefore should be regularly tested to ensure that any occurrences of drift are detected soon enough for the problem to be mitigated

B.

The model suffers from drift and therefore the performance standard should be eased until a new model with more transparency can be developed

C.

The model suffers from corruption and therefore should be reloaded into the computer system being used, preferably with a method of version control to prevent further changes

D.

The model suffers from a lack of transparency and therefore should be regularly tested to ensure that any progressive errors are detected soon enough for the problem to be mitigated

B.

Selecting training data by purposely including all known faulty conditions

C.

Selecting testing data from a different dataset than the training dataset

D.

Selecting testing data from a boat manufacturer's bolt longevity data

Options:

A.

Labeling the data correctly

B.

Minimizing the amount of time spent training the algorithm

C.

Selecting the correct data pipeline for the ML training

D.

Grouping similar products together before feeding them into the algorithm

Questions # 25:

You have been developing test automation for an e-commerce system. One of the problems you are seeing is that object recognition in the GUI is having frequent failures. You have determined this is because the developers are changing the identifiers when they make code updates. How could AI help make the automation more reliable?

Options:

A.

It could identify the objects multiple ways and then determine the most commonly used and stable identification for each object

B.

It could modify the automation code to ignore unrecognizable objects to avoid failures

C.

It could dynamically name the objects, altering the source code, so the object names will match the object names used in the automation

D.

It could generate a model that will anticipate developer changes and pre-alter the test automation code accordingly

Expert Solution

B.

Output data or intermediate data

C.

Video frame speed or aspect ratio

D.

Data frameworks or machine learning frameworks

Questions # 27:

A ML engineer is trying to determine the correctness of the new open-source implementation *X", of a supervised regression algorithm implementation. R-Square is one of the functional performance metrics used to determine the quality of the model.

Which ONE of the following would be an APPROPRIATE strategy to achieve this goal?

SELECT ONE OPTION

Options:

A.

Add 10% of the rows randomly and create another model and compare the R-Square scores of both the model.

B.

Train various models by changing the order of input features and verify that the R-Square score of these models vary significantly.

C.

Compare the R-Square score of the model obtained using two different implementations that utilize two different programming languages while using the same algorithm and the same training and testing data.

D.

Drop 10% of the rows randomly and create another model and compare the R-Square scores of both the models.

Questions # 28:

A company is using a spam filter to attempt to identify which emails should be marked as spam. Detection rules are created by the filter that causes a message to be classified as spam. An attacker wishes to have all messages internal to the company be classified as spam. So, the attacker sends messages with obvious red flags in the body of the email and modifies the "from" portion of the email to make it appear that the emails have been sent by company members. The testers plan to use exploratory data analysis (EDA) to detect the attack and use this information to prevent future adversarial attacks.

How could EDA be used to detect this attack?

Options:

A.

EDA can help detect the outlier emails from the real emails

B.

EDA can detect and remove the false emails

C.

EDA can restrict how many inputs can be provided by unique users

D.

EDA cannot be used to detect the attack

Their model accuracy and other functional performance parameters have not yet reached their desired level.

Which ONE of the following factors is NOT a factor affecting the ML functional performance?

SELECT ONE OPTION

Options:

A.

The data pipeline

B.

The quality of the labeling

C.

Biased data

D.

The number of classes
