Responsible AI Development Quiz Answers

Question 1)
Human biases lead to bias in machine learning models. Unconscious biases exist in our data and exist in two forms. What are the two forms of unconscious biases in data?

• There are the human biases that exist in data because data found in “data silos” has existing biases with regard to properties like gender, race, and sexual orientation. We can also run into human biases which arise as part of our data collection and labeling procedures.
• First, there is human bias as a result of reporting, data collection, and labeling. Second, there is human bias as a result of data visualization and analysis.
• There are the human biases that exist in data because data found in “the world” has existing biases with regard to properties like gender, race, and sexual orientation. For example, there may be reporting bias by our subjects because they only choose to reveal certain aspects about themselves or their opinions. We can also run into human biases which arise as part of our data collection and labeling procedures.
• All of the options are correct.

Question 2)
The impact of biases in collecting data and labeling data affects the entire machine learning pipeline. The biases in the original data are going to be reflected downstream in our models and consequently are going to result in potentially biased outcomes. You need to create a checklist for situations where you should watch out for bias-related issues. What questions should this checklist include?

• Does your use case or product specifically use any of the following data: biometrics, race, skin color, religion, sexual orientation, socioeconomic status, income, country, location, health, language, or dialect?
• Does your use case or product use data that is likely to be highly correlated with any personal characteristics (for example, zip code or other geospatial data is often correlated with socioeconomic status and/or income; image/video data can reveal information about race, gender, and age)?
• Could your use case or product negatively affect individuals’ economic or other important life opportunities?
• All of the options are correct.

Question 3)
Fill in the blank. One of the key tools to help in understanding inclusion and how to introduce inclusion across different kinds of groups across your data is by understanding the __________________________.

• Confusion matrix
• Evaluation regression matrix
• Sigmoid matrix
• Equality of opportunity matrix

Question 4)
Which of the following is an example of a “false negative”?

• The label says there is no face, but the model finds a face. Perhaps there is a statue in the image and the model falsely identifies it as a face.
• When the label says something exists and the model doesn’t predict it—that’s a false negative. So, in the face detection example in this lesson, the model says that there is no face in the image—when the image’s label says there *is* a face.
• The label says there is a face, and the model finds a face.
• The label says there is no face, and the model finds no face.

Question 5)
Datasets can contain hundreds of millions of data points, each consisting of hundreds (or even thousands) of features, making it nearly impossible to understand an entire dataset in an intuitive fashion. The key here is to utilize visualizations that help unlock nuances and insights in large datasets. Which tool would be most appropriate?

• SQL
• Firebase
• Facets
• Pandas

Question 6)
Which approach is followed to achieve a better performance across subgroups?

• Equality of opportunity
• Evaluation metrics
• Confusion matrix
• None of the options are correct.

Question 7)
The confusion matrix helps which of the following?

• Understanding inclusion and how to introduce inclusion across different subgroups within your data
• Evaluating performance in machine learning
• Both of the options are correct.
• None of the options are correct.

Question 8)
What is it called when the label says something doesn’t exist, but the model says it exists?

• False negative
• False positive
• True positive
• None of the options are correct.
