NFL Rushing Analytics

Aaron Augustine

For my project, I studied various predictors that influence rushing yards in the National Football League. I used Random Forests to predict the number of yards gained on a rushing play. I will talk about the steps I went through to clean and prepare the data, my model building processes, and some issues that I encountered along the way. Visualizations were constructed to further investigate some of the more important predictors in the model.



Dr. Hooks Awarded WSU Professor of the Year


Winona State University statistics and data science Professor Tisha L. Hooks has been selected as Professor of the Year.

The Professor of the Year designation is awarded annually by the WSU Student Senate on behalf of the student body. Students vote for a professor that goes above and beyond for their students. These professors serve as exemplars in being accommodating, accountable, engaging to students, making an effort to have their curriculum relevant to daily life, and aiming to make their courses affordable for students to participate in. This award is run through Student Senate, but it is voted and decided by all students.

A professor in the WSU Department of Mathematics and Statistics, Hooks has been teaching at Winona State since 2006. She received her Bachelor of Science degree in Mathematics from the University of Nebraska at Kearney and a PhD in Statistics from the University of Nebraska – Lincoln.

Hooks, who initially had no intention of teaching, heeded the call to the classroom during graduate school, and she has never looked back. “Showing students the value of statistics and helping them succeed – especially when they thought they couldn’t, was extremely fulfilling. It still is today.”

Initially taken by surprise, Hooks is honored and grateful to have been chosen among “so many gifted teachers across campus…we pour so much of ourselves into our jobs as educators, and though we don’t expect to be recognized for our efforts, hearing that we have made a difference certainly helps to fill us back up again.”

Hooks honors the collective experience and professional collaboration of her WSU colleagues, with special thanks to her fellow statisticians and data scientists, saying “They are continually striving for excellence, which also pushes me to be the best teacher I can be. Together we have spent countless hours developing a curriculum that is relevant, engaging, and effective.”

“This award is special to me because it comes from the students, confirmation that I am helping students in the ways I had hoped when I changed my career path years ago. I just feel lucky to be a part of it all.”

Implementing SQL for Table Toolz, Project Structures for Data Science

Daniel Lew

I will be talking about implementing SQL for Tabletoolz, which is a data manipulation library inspired by R’s Dplyr in Python, what I did and what I learned from the project. Also, I will be sharing about using a project structure for data science.

Internship Experience: Supply Chain Intern at Fastenal

Danielle Buoy

Fastenal, an industrial supplies company based in Winona, MN has worked for years distributing goods used by hundreds of businesses. Inventory movement is emphasized in their supply chain department, where I’ve contributed my internship skills. Handling product redistribution amongst the branches, facilitating vendor returns, and assisting with liquidations of non-moving parts are three main areas of focus. An essential part of the process as a whole is to minimize and reduce noncontributing inventory via utilization of programs, tools, and databases. Optimization of productivity and profitability throughout the company is a major takeaway of my supply chain duties.





      Internship: Fastenal Supply Chain and Data Team

Peyton Schumacher

I will speak about my duties at Fastenal as a Supply Chain Analyst and Data Team Member, as well as creating and refining new and existing processes in our Supply Chain.

Methods of Data Imputation

Carson Howells

Imputation is the process of filling in missing values in data sets. This project is exploring which method of data imputation is best for different data types.





      Deep Learning Classification of Retina Images: Detecting Diabetic Retinopathy

Mikolaj Wieczorek

Diabetic retinopathy (DR) is a common eye disease that causes vision loss for people with diabetes. It is one of the fastest growing causes of preventable blindness, and about 45% of Americans diagnosed with diabetes have some stage of DR. As the disease has no symptoms in early stages and treatments begin after the vision is already somewhat affected, early detection is of pivotal value to diabetic patients. The aim of this project is to build a deep learning classification model that could assist in early detection and severity grading of DR. The final results are obtained by implementing a Dense Convolutional Network Architecture model that yields 98% classification accuracy. Further study is being considered with application of larger training data and to deploy the final model as a web app.

Using Natural Language
Processing to Analyze News Bias

Bradley Erickson

As we live in the information age, finding reliable information becomes more and more difficult. All news sources contain bias, thus anything someone reads could be misinformation or interpreted differently. This research scrapes thousands of articles from many sources relating to 5 controversial topics: the impeachment, abortion, immigration, gun control, and climate change. We use unsupervised learning techniques to rank and filter out the top sentences by giving more weight to unbiased, more credible sources. This information will form an extractive-based summary. Finally, we compare the language used among 3 bias groups: left bias, no bias, and right bias. The research provides insights into the current bias state of news reporting.





      Social Influence and the Freshman Experience

Adam Funk

We investigated the relationship between time at a university and who freshmen are most influenced by at that given time. The study took a subset of 1000 freshmen from the Winona State University class of 2023 and asked about different influence factors and changes in behavior over the course of 10 weeks. Different surveys were sent out at 1 week, 3 weeks, 6 weeks, and 10 weeks. Questions on who they were influenced by, both negatively and positively, were asked, as well as groups they were a part of and whether they felt they had changed as a person. We also attempted to monitor the change over time of specific individuals through an identification code, which was unsuccessful. However, summary statistics of each time point were successfully collected and reported.

Identifying Pulsar Stars

Alexander Phillips

Pulsar stars, neutron stars that appear as rhythmic pulses of radio waves, are of great importance to astronomers as measuring devices. Scientists from two observatories in Australia and Germany compiled a dataset of 17,898 potential pulsar signals, recording data on each signal’s integrated profile and dispersion measure. This study considers variations on a logistic regression model to classify radio signals as pulsar stars or noise. The optimal predictive model considers the mean, standard deviation, skewness, and kurtosis of both the integrated profile and the dispersion measure, though a model with only the four best predictors also reaches a high level of accuracy.




      Analyzing Filings Sentiment for Applications in Finance

Marshall Will

There has been increasing use of using sentiment in financial reports to create a better understanding of what is being read and how that can affect market prices. Analyzing sentiment for financial research has been around for a while, but over the past decades, there has been an increasing interest in looking at how changes in sentiment can affect market prices. Past research has shown that measuring sentiment can be used to generate Alpha and gauge a firm’s fundamentals. For my capstone, I looked at the sentiment of 10-K and 10-Q filings for publicly traded securities in the NASDAQ and NYSE from 1993 to 2018 to see if it is possible to predict if a security will rise in price based on the change in word sentiment in these public filings.
