Week 02: Big Data, Artificial Intelligence, and Ethics Coursera Quiz Answers

Natural Language Processing (NLP) Assignment Task

Q.1. For this assignment, you will gain insight on two ‘personalities’ by doing Natural Language Processing on a sample speech from each personality. This quiz is designed to assign different learners two personalities at random, so you might see slight variances than your peers.

Y​ou are being assigned the following two personalities:

D​onald Trump and Hillary Clinton

Y​ou can click on each of their names to access their speeches or you can find them as a resource under “Course Resources” in this course.

A​re you ready to get started?

  • Y​es, I have obtained both speeches for my two personalities and am ready to get started.
  • N​o, I am not ready to do this assignment, but I know my two personalities and have either already downloaded their speeches through the links above or will access them later under “Course Resources”.

Module 2 Quiz

  • The consultant must have hacked Twitter, which is unethical
  • Doing this is illegal
  • This data may not be representative

Q.3 In lecture, we have seen an example of a big data study that used mobile phone trace data. It seemed to suggest that in an African country, there are many more young women than in Latin America. What did we take away from this?

  • Data-fusion led to the end of theory, which can be tackled with artificial intelligence
  • Many young men left Africa as economic refugees to Europe, while women are better treated in Latin America
  • Skewed mobile phone penetrations introduced a sampling bias
  • Mobile phones are the best source to identify population characteristics in developing countries

  • Algorithm prediction doesn’t mean it happens or will happen in reality
  • It is immoral to use algorithm to make such decisions on human life in reality
  • Algorithm prediction is not higher than human psychologists’ prediction

Q.7. Why is data mining, per definition, “always statistical (and therefore seemingly rational) discrimination”? Because the point of data mining is to:

  • Statistically make sense of social hierarchical structure
  • Conclude the general rules that applies to everyone
  • Use machine learning, which uses code manipulated by computer scientists
  • Provide a rational basis upon which to distinguish between individuals

Q.8. According to Washington Post, Trump’s administration alleged that manufacturing decline increases abortion, infertility, and spousal. What is the mistake in this allegation?

  • Summer might be a confounding variable
  • Eating ice could cause people to watch baseball
  • The study might not be replicated and might be a victim of the replication crisis

Q.10 The original ‘Google Flu Trend’ algorithm predicted the outbreak of the flu from Google searches. Why did the algorithm from 2009 not work anymore when it was applied again in 2013?

  • Replication studies always fail (“replication crisis”)
  • It was not Google itself, but some academics who did the 2013 study
  • There was less flu variation in 2012/2013, so less data to work with
  • Reality changed: people Googled different things a few years later

Q.11What does Lucas’ critique point out?

  • Making the world a better place will require help from artificial intelligence, but it is dangerous to empower machines
  • Unethical big data work has to be regulated, especially automated weapons like slaughterbots
  • Changes in policy will systematically alter econometric results if the used computer simulations are agent-based
  • Using data to design interventions, one cannot assume that the same predictions will still hold after the intervention

More About This Course

This course gives you context and first-hand experience with the two major catalyzers of the computational science revolution: big data and artificial intelligence.

With more than 99% of all mediated information in digital format and with 98% of the world population using digital technology, humanity produces an impressive digital footprint.

In theory, this provides unprecedented opportunities to understand and shape society. In practice, the only way this information deluge can be processed is through using the same digital technologies that produced it.

Data is the fuel, but machine learning is the motor to extract remarkable new knowledge from vast amounts of data.

Since an important part of this data is about ourselves, using algorithms in order to learn more about ourselves naturally leads to ethical questions.

Therefore, we cannot finish this course without also talking about research ethics and about some of the old and new lines computational social scientists have to keep in mind.

In hands-on labs, you will use IBM Watson’s artificial intelligence to extract the personality of people from their digital text traces, and you will experience the power and limitations of machine learning by teaching two teachable machines from Google yourself.

WHAT YOU WILL LEARN

  • Define and discuss big data opportunities and limitations.
  • Work with IBM Watson and analyze a personality through Natural Language Programming (NLP).
  • Examine how AI is used through case studies.
  • Examine and discuss the roles ethics play in AI and big data.
