Cracking the Code on Credit Cards at Datathon 2018

Anyone who has ever tried to formulate and answer their own research question knows that it means entering uncharted waters. This past weekend the hundreds of students in Duke Datathon 2018 did just that, using only their computer science prowess and a splash of innovation.

Here’s how it worked: the students were provided three data sets by Credit Sesame, a free credit score estimator, and given eight hours to use their insight and computer science knowledge to interpret the data and create as much value for the company as they could. Along the way, Duke Undergraduate Machine Learning (DUML), the organization hosting the event, provided mentors and workshops to help the participants find direction and achieve their goals.

This year was the first such ‘Datathon’ event to take place at Duke. The event attracted big-name sponsors such as Google and Pinterest and was made possible by the DUML executive team, headed by co-presidents Rohith Kuditipudi and Shrey Gupta (to see a full list of event sponsors, click here).

DUML faculty advisor Dr. Rebecca Steorts said that even the planning of the event transcended disciplines: one of her undergraduate students and co-president of DUML, Shrey Gupta, found a way to utilize statistics to predict how many people would be attending. “It’s all about finding computational ways of combining disciplines to solve the problem,” Steorts said, and it’s very apparent that her students have taken this to heart.

After more than an hour of deliberations, the eight top teams were selected and five finalists were asked to present their findings to the judges. The winning team (Jie Cai, Catie Grasse, Feroze Mohideen) proposed a way to gauge which customers who create trial accounts are most likely to be profitable, by using a computer filtering program to predict likely customer engagement based on customer-supplied data and their interaction with the free trial. Other top teams discussed similar topics with different variations on how Credit Sesame might best create this profile to determine who the “valuable” customers are likely to be.

DUML hosts other events throughout the year to engage students such as their MLBytes Speaker Series and ECE Seminar Series. To learn more about Duke Undergraduate Machine Learning, click here.

Falling Out of Love With Science and Our Civic Duties

Last Friday, I attended Falling Out of Love with Science, a lunch function during which Milan Yager,executive director of the American Institute for Medical and Biological Engineering, discussed why those of us interested in scientific research should care about the actions of prominent politicians, especially those that relate to the underfunding of scientific research.

Milan Yager of AIMBE

Milan Yager is the executive director of the American Institute for Medical and Biological Engineering.

Before attending Yager’s talk, I guess I didn’t quite realize how much of innovation was enabled by government funding. Many revolutionary discoveries are made possible through the NIH (https://www.nih.gov) that we don’t even realize we use on a daily basis.

However, as I came to realize, public support for research funding is jeopardized by the propagation of fake news defeating the need for concrete scientific research, hence propelling research under-funding. Over time, funding for the NIH and other government research funding has declined, which has slowed American innovation.

What I enjoyed most about his talk however, was the unexpected motivational turn that it took at the end. He discussed how we, as young researchers invested in finding our personal truths through science, needed to use our voices to stand up against the proliferation of myths in politics in favor of concrete facts.

NIH funding trends

Here’s a curve we definitely want to bend: NIH research funding has flattened and fallen.

Though this can be done in different ways, Yager made sure to point out how essential it is for Americans to vote, citing a statistic that points out that 20 percent of Americans don’t vote because they are “simply too lazy.” (Learn how to register to vote in North Carolina.)

He also encouraged us to send letters to our senators, rally for what we believed in, and not give up on our goals in the face of adversity — something that he called “sitting at the table.” Yager points out that if you don’t “sit at the table,” then your issue won’t get the necessary exposure needed for it to be fixed.

What can we, as Duke students, take away from what Yager had to say? Mainly this: Duke is a research institution that is partially made capable by government funding; for our capacity for research to be continued to be fully realized, we must use our voices to make sure that the propagation of ‘fake news’ does not cut funding for factual research.

This is mainly achieved by voting– those who perpetuate false “facts” in order to remain in power must be replaced with those who realize the importance of scientific research.

Perhaps, for society to fall back in love with science, we need to fall out of love with the myths propagated by tribal politics.

New Blogger Rebecca Williamson: The Moon and Some Stars

Hello! My name is Rebecca Williamson, and I am a freshman here at Duke University. Coming into college, I plan to major in economics, but that could very well change. As for my interests outside of the classroom, I enjoy singing and theater and am a member of Out of the Blue, one of the all-female a cappella groups here at Duke!

Rebecca Williamson, Duke 2022

I fell in love with Duke the second I stepped on campus. I am excited to see what Duke has to offer me, but more importantly, what I can offer to Duke.

My interest in science, specifically astronomy, was piqued at a very young age. By age six, I had not one, but three,  Moon in my Room light up toys (remote controlled models of the Moon that scrolled through the waxing and waning phases of the Moon at the touch of a button) mounted in my bedroom. By nine, I had the entire planetary system (yes, including Pluto) hanging from my ceiling. Though I cannot say that my interests remain with astronomy, it is what first got me invested in science. I have since gained interest in the natural sciences and animal sciences, though every so often I do press some of the buttons on my Moon in my Room remote.

My love of writing, however, was spawned by my love of theater. As an active member of my high school’s theater community, I was roped into being a part of, and eventually became the president, of my school’s Cappies Critics team. As a Cappie, I was expected to watch local high school plays and musicals and write critical, holistic reviews of them. This program jump-started my love for writing and helped me to develop my own unique journalistic voice.

I also hope to incorporate my interests in music and theater into my inquiries and document scientific research surrounding music and the arts in the Duke community.
