LA JOLLA, CALIF., April 1, 2019 – Developing how the heart forms and brain works. How to analyze sarcasm computationally. Harnessing computers to develop campaign rhetoric that delivers voters across the political spectrum. The Halıcıoğlu Data Science Institute (HDSI) at the University of California San Diego has announced new funding for these and other innovative research projects helping develop the next generation in data science leadership.

HDSI has awarded research undergraduate scholarships to 17 students funding 14 projects total this spring quarter. In the inaugural year of the Undergraduate Scholarship Program, each project is granted a total $2,500-$6,000. The scholarship program goal is to provide hands-on training in real-world projects to emerging data science talent, noted Bradley Voytek, an HDSI Fellow and associate professor in the Department of Cognitive Science at UC San Diego.

More than 50 students competed for the 14 scholarship project awards for the spring academic term. “It’s impressive what a hunger our students have developed to use the newest data science tools to uncover answers to important questions,” said Voytek, who directs the Institute’s scholarship program.

This is the first full academic year for the Halıcıoğlu Data Science Institute (pronounced Haw-li-jyo-loo), which oversees one of the largest data science majors in the nation. The cross-disciplinary program educates more than 600 undergraduate students, and has an expanding graduate program. The newest funded undergraduate research projects drew students from more than 14 different academic disciplines – from mathematics to music, and data science to cognitive science. That diversity highlights the breadth of need and appeal of data science applications in society, noted Voytek.

Winning projects include data-science-based research exploring such subjects as: Quantum mechanics, how the brain works, how the heart forms, and even enhancing leisure activities such as fantasy sports games. The scholarships have proven to be a successful step in fulfilling the mission of the unique institute to serve as a data science hub drawing across academic boundaries, notes HDSI Director Rajesh Gupta.

“Our scholarships are a good way to develop research strengths in the undergraduate cohort, and for faculty and industry partners to work directly with our students on dynamic projects,” said Gupta, who is also a UC San Diego Distinguished Professor and the Qualcomm Endowed Chair in the Department of Computer Science and Engineering at the Jacobs School of Engineering.

Among the award-winning projects:

The Importance of Political Rhetoricbeing researched by a team of Data Science majors: Sravya Voleti, Austin Le and Zahra Masood. The team plans to analyze how politicians can boost their approval ratings by optimizing language to appeal to voters outside their target demographics. The Data Science students to use statistical modeling and make predictions about how a politician’s word choice could affect campaign outcomes. “We hope to discover what kind of language makes politicians successful,” their proposal states, “to create a definitive model that will help future politicians optimize their success in elections.”

Deep Learning for Sarcasm Detection. Data Science major Takashi Yabuta will use his scholarship to develop algorithms that help machines better understand nuances of human language. Yabuta notes that the challenge of Natural Language Processing (NLP), which is basically talking to voice recognition computer applications like Siri and Alexa, has been in the classification of sarcasm. Sarcasm tends to confound computers because it’s negative speech that appears positive. He hopes to create new approaches to improve algorithm performance for NLP.

The HDSI Undergraduate Research Scholarship program is geared to producing results, with scholars submitting final reports highlighting accomplishments. Each awardee works with a mentor to develop analytical skills, data science portfolios, and foster novel data-driven approaches to problem solving. Mentors include: Virginia de Sa, professor of Cognitive Science and HDSI Associate Director; Pavel Pevzner, an HDSI faculty affiliate in Computer Science and Engineering; Federico Rossano, and Eran Mukamel, of the Department of Cognitive Science; Erin Rose Glass, Digital Scholarship Librarian, Geisel Library; Robert Twomey, lecturer in Data Science and postdoctoral scholar with the Arthur C.
