*Saturday, August 1, 1:00 p.m. - 3:50 p.m., Philadelphia Marriott Downtown, Grand Ballroom C*

Analyzing complex data requires both a strong theoretical foundation and applied data science skills to ensure that data is used responsibly and ethically. However, many definitions of data science focus only on the intersection of statistics and computer science, without any focus on what mathematical skills are needed to be a successful data scientist. As the mathematics community continues to grapple with the field of data science, educators are producing recommendations on data science curriculum and how to best prepare the future data scientist workforce. Therefore, it is crucial to consider the role of mathematics in the data science curriculum, and how to broaden access to data science career paths for mathematics students.

This session features leaders in the intersection of mathematics and data science who will discuss the role of mathematics in data science, in many different forms. This session is formatted as talks from six experts in the applications of mathematics in data science. The session will appeal to any MathFest attendees interested in strengthening skills needed for data science, understanding the applications of mathematics to data science, or pathways into data science careers.

### The Convergence of Multiple Traditional Disciplines Catalyze the Field of Data Science

*1:00 p.m. - 1:20 p.m.*

**Talitha Washington**, *Howard University*

**Erick Jones**, *University of Texas at Arlington*

#### Abstract

With the abundance of data, new skills will be needed to prepare students for jobs that do not yet exist. Via the convergence of mathematics with other disciplines, such as engineering, we can enhance the student's ability to solve complex societal problems. This presentation will share recent advancements in the innovation ecosystem that utilize data science which are grounded in mathematics.

### When Life is Linear: Data Science and Linear Algebra

*1:30 p.m. - 1:50 p.m.*

**Tim Chartier**, *Davidson College*

#### Abstract

Data is a huge and growing part of our world. A major tool to manipulate and study this data is linear algebra. This talk will discuss concepts of matrix algebra that lay at a foundation of data science. We will see how to use linear algebra in such areas as compression, clustering, ranking, and text analysis.

### Machine Learning Analysis for Fulfillment of Per Diem Nurse Shifts

*2:00 p.m. - 2:20 p.m.*

**Semere Habtemicael**, *Wentworth Institute of Technology*

#### Abstract

This project was done as part of the MAA PIC Math program. PIC Math aims to increase awareness among math faculty and students about non-academic career options; teach faculty how to make industry connections to provide research experiences for their students to work on real problems coming directly from business, industry, or government; and prepare students for industrial careers. Over spring of 2019, I had three industrial collaborators from IntelyCare, Mitre, and AIR-WorldWide. IntelyCare is a nursing agency that aims to solve the per diem nurse-staffing issue by matching qualified nursing professionals with health care facilities. They have built an on-demand, tech-enabled, health care staffing platform that serve longterm facilities in six different states. The problem is twofold, first how to forecast the demand for nurses so that hospitals can have a better way to know how many substitute nurses may be needed for any time period. The second problem is to determine how long does it take for a nursing shift to fill at a given price. Several statistical analysis like machine learning and survival analysis are implemented to provide health care facilities with an understanding as to how they can increase the likelihood of their posted shifts being filled, and how long they can expect to wait for the shifts to be filled.

### Preparing for Data Science: A Math Educator and Industry Scientist Perspective

*2:30 p.m. - 2:50 p.m.*

**Elin Farnell**, *Amazon Web Services*

#### Abstract

After eight years in academia, I transitioned into a data scientist role in industry. In this talk, I will draw on my experience in academia, my involvement as a faculty member in the PIC Math program, my work in industry, and a variety of conversations and short interviews with other data scientists in order to engage with the question of how mathematics plays a role in the field of data science. Topics of discussion will include foundational math classes, important mathematical techniques, and the data scientist skillset.

### Underneath the Hood: Teaching the Theory and Practice of Optimization for Data Science

*3:00 p.m.- 3:20 p.m.*

**Emily Evans**, *Brigham Young University*

#### Abstract

Nearly every question in data science is, or can be formulated as, an optimization problem. How can I carry out a task with the fewest resources? How can I minimize my risks? How can I do the most good? All of these are optimization problems. In this talk, I will address why a strong knowledge of optimization techniques is important, some of the key algorithms to know for data science, and best practices for teaching optimization to an aspiring data scientist.

### The Necessity of a Math for Data Science Course

*3:30 p.m. - 3:50 p.m.*

**Chris Malone**, *Winona State University*

**Todd Iverson**, *Winona State University*

**Brant Deppa**, *Winona State University*

**Lee Windsperger**, *Winona State University*

**Aaron Wangberg**, *Winona State University*

#### Abstract

Mathematical foundations is one of the key competencies of the 2016 Park City Math Institute’s Curriculum Guidelines for Undergraduate Programs in Data Science. A recent five-year program review of the Data Science program at Winona State University highlighted the necessity of additional learning outcomes centered on mathematical foundations. As a result, a new course is currently being developed to address the mathematical shortcomings of our existing curriculum. The topics to be covered in this new course will be centered around optimization, linear algebra, and probability. Methods and applications will be the primary focus of this course.
