Q

Which of the 4 guiding principles is:

Ensure that AI systems operate as they were originally designed, respond to unanticipated conditions, and resist harmful manipulation.

A

Reliability and safety -

To build trust, it’s critical that AI systems operate reliably, safely, and consistently under normal circumstances and in unexpected conditions. These systems should be able to operate as they were originally designed, respond safely to unanticipated conditions, and resist harmful manipulation.

Q

Which of the 4 guiding principles is:

Implementing processes to ensure that decisions made by AI systems can be overridden by humans.

A

Accountability -

The people who design and deploy AI systems must be accountable for how their systems operate. Organizations should draw upon industry standards to develop accountability norms. These norms can ensure that AI systems are not the final authority on any decision that impacts people’s lives and that humans maintain meaningful control over otherwise highly autonomous AI systems.

Q

Which of the 4 guiding principles is:

Provide consumers with information and controls over the collection, use, and storage of their data.

A

Privacy and security -
As AI becomes more prevalent, protecting privacy and securing important personal and business information is becoming more critical and complex. With AI, privacy and data security issues require especially close attention because access to data is essential for AI systems to make accurate and informed predictions and decisions about people. AI systems must comply with privacy laws that require transparency about the collection, use, and storage of data and mandate that consumers have appropriate controls to choose how their data is used Reference:

Q

T or F:

Providing an explanation of the outcome of a credit loan application is an example of the MS transparency principle for responsible AI.

A

T

Achieving transparency helps the team to understand the data and algorithms used to train the model, what transformation logic was applied to the data, the +nal model generated, and its associated assets. This information offers insights about how the model was created, which allows it to be reproduced in a transparent way.

A

F

Inclusiveness mandates that AI should consider all human races and experiences, and inclusive design practices can help developers to understand and address potential barriers that could unintentionally exclude people. Where possible, speech-to-text, text-to-speech, and visual recognition technology should be used to empower people with hearing, visual, and other impairments.

Accuracy is simply the proportion of correctly classi+ed instances. It is usually the +rst metric you look at when evaluating a classi+er. However, when the test data is unbalanced (where most of the instances belong to one of the classes), or you are more interested in the performance on either one of the classes, accuracy doesn’t really capture the effectiveness of a classi+er.

61
Q

T or F

For a regression model, labels must be numeric.

A

T

Box1:Yes-
For regression problems, the label column must contain numeric data that represents the response variable. Ideally the numeric data represents a continuous scale.

62
Q

T or F

For clustering model, labels must be used.

A

F

No-
K-Means Clustering -
Because the K-means algorithm is an unsupervised learning method, a label column is optional.
If your data includes a label, you can use the label values to guide selection of the clusters and optimize the model. If your data has no label, the algorithm creates clusters representing possible categories, based solely on the data.

63
Q

T or F

For a classification model, labels must be numeric.

A

F

No-
For classification problems, the label column must contain either categorical values or discrete values. Some examples might be a yes/no rating, a disease classification code or name, or an income group. If you pick a noncategorical column, the component will return an error during training.
