Opinion: Using Artificial Intelligence May Not Eliminate Biases

One of the major tools of artificial intelligence is the neural net, which models the way the neurons in our heads behave. Although the implementation of a neural net on the computer is mathematically complicated, below I describe an example that closely models the way that implementation works but is easier to understand. This will enable me to answer three questions about neural nets: (1) Do they make unbiased decisions? (2) Can we know the rules a specific neural net uses when making a decision? (3) Do neural nets think?

Suppose you want to organize a group of people to decide whether to grant a mortgage after reading the application. You decide to create a number of teams to read the application. Each team evaluates a different factor affecting the possibility of default; each team member evaluates a different component of that factor. For example, one team might evaluate the finances of the applicant. Another team might evaluate the future financial climate, etc. For the team evaluating the applicant's finances, one member might evaluate the applicant's current income. Another team member might evaluate the applicant's assets, etc. A team then makes a team decision via a yes-or-no vote. These team decisions then become individual votes on a final yes-or-no decision. This process may seem cumbersome, but it closely resembles the structure of a neural net.

An important feature of this voting procedure is that the votes are weighted according to how successful the voters have been in the past in predicting that an applicant avoided defaulting on the mortgage loan. You start by allocating each team member 1,000 votes and each team 1,000 votes. When a loan is in default, those team members who voted to grant the loan lose a few of their votes, while those team members who voted against granting the loan gain a few votes. Conversely, when the loan is not in default those who voted yes gain a few votes, and the naysayers lose a few votes. The same actions are taken for the votes of the teams. In neural net terminology this "feedback" is the mechanism for "reinforcement."

Now, assume that all the members of the teams have lots of leisure and we can train their network by having them read the applications of thousands of mortgage applications without telling the team members that they were already given a green light (ignoring those that have been rejected) and whose fate – successful completion or default – have been recorded. After they read an application, they make a decision, and the number of votes they have are adjusted. After this training, the system stabilizes and can now be used to evaluate new applications.

In technical terms, the members of the teams are "nodes" (objects that receive or send data) as are the team captains. The number of votes each team member has measures the strength of the "connection" between the team member node and the captain node. And the number of votes the captains have measure the strength of the "connection" between the captain nodes and the overall decision, itself a node. The member nodes constitute one "layer," the captains a second layer, and the decision a third layer. In practice, neural nets can have various numbers of layers.

Now, to answer the questions I posed at the beginning.

(1) Do they make unbiased decisions?

For the sake of discussion, assume the members of the net above are all unbiased. The choice of the training set (the thousands of mortgage applications) may bias the net's output. For example, if most of the mortgage applicants were white males, the net may be trained to ignore relevant characteristics of female or black applicants. Then the net may be biased in favor granting mortgages to those applicants or it may be biased in favor of denying their applications.

(2) Can we know the rules a specific neural net uses when making a decision?

An algorithm is a set of rules for solving a problem. For example, in tic-tac-toe, one rule states that the person making the first move can avoid losing by placing a mark in the center box. In the example above I state an algorithm for a mechanism for deciding when to grant a mortgage. But that algorithm tells us nothing about the actual basis for the decision. In that sense, I have designed a "black box" process that provides no insight into the reasoning behind the decision; its decision algorithm is hidden. Neural nets suffer from this problem; we cannot explain their decisions.

(3) Do neural nets think?

When it comes to thinking, there is no there there.

Carroll University Launches Major In Artificial Intelligence

Subscribe to BizTimes Daily – Local news about the people, companies and issues that impact business in Milwaukee and Southeast Wisconsin.

Beginning this fall, Carroll University will offer a new artificial intelligence major for its students, the university announced on Tuesday.

Amid a time of growing demand for AI skills in the workforce, Carroll University's upcoming AI major will provide students with courses covering machine learning algorithms, natural language understanding, speech synthesis, image recognition, logical reasoning, data analysis and robotics, according to the university's news release.

While higher education institutions have increasingly been working to provide AI education opportunities, majors focused solely on AI are rare.

"We are extremely excited to offer this new undergraduate major in AI, building on the success of our recent offering of an AI minor," said Margaret Polk, an associate professor of computer science at Carroll University. "From all accounts, while there are AI courses and concentrations within majors found at other universities, our new major is one of only two strictly focused and so-named 'Major in Artificial Intelligence' offerings at the university undergraduate level in our geographic area."

The University of Wisconsin-Eau Claire announced earlier this month that it would begin offering a major in artificial intelligence beginning in fall 2025.

Carroll University, located in Waukesha, joins a growing list of Milwaukee area higher education institutions that are expanding AI education opportunities. Last fall, Waukesha County Technical College began offering a two-year AI degree, becoming the first technical college in the state to offer this type of program.

Milwaukee School of Engineering also recently began offering three AI certificates in fall 2024. MSOE also incorporates AI education in its computer science and machine learning degree programs.

"There are undergraduate computer science majors and engineering majors degrees that have an AI concentration, but the actual named (AI) major is the rarity," Polk said.

Ohio State Students To Incorporate Artificial Intelligence In Every Major

Bellamkonda, executive vice president and provost, said.Students at Ohio State will also be required to take an AI Skills seminar and the university will implement workshops into existing class framework.The university emphasized that the focus on AI is not meant to allow students to use AI to claim AI-generated content as their own work for assignments.At least six university offices will be tasked with issuing guidance for helping students maintain academic integrity while using AI.

COLUMBUS, Ohio —

Beginning this fall, every Ohio State University student will be asked to use artificial intelligence in the classrooms.

The effort for students to use AI more in their studies comes as part of the university's AI Fluency Initiative, which is designed to embed AI into the undergraduate curriculum.

The program will prioritize Ohio State's incoming freshmen class.

Ohio State aims to have each 2029 graduate fluent in the use of AI in their respective educational fields.

"Through AI Fluency, Ohio State students will be 'bilingual' — fluent in both their major field of study and the application of AI in that area," Ravi V. Bellamkonda, executive vice president and provost, said.

Students at Ohio State will also be required to take an AI Skills seminar and the university will implement workshops into existing class framework.

The university emphasized that the focus on AI is not meant to allow students to use AI to claim AI-generated content as their own work for assignments.

At least six university offices will be tasked with issuing guidance for helping students maintain academic integrity while using AI.
