A Computer Vision Framework for Multi-Class Player Detection and Tracking in Soccer Broadcast Footage

Smart Soccer Insights

The use of artificial intelligence in soccer analytics is rapidly expanding, yet most professional tracking systems still rely on expensive multi-camera setups that limit accessibility for lower-resource teams. This paper investigates whether coordinate and event-level information can be reliably extracted from raw broadcast footage using a single-camera by developing a system that combines a YOLO object detection model, a keypoint pitch detector, and the ByteTrack tracking algorithm to identify and track players, referees, goalkeepers, and the ball. The model was trained on a custom dataset containing Bundesliga, NCAA, and UPSL broadcast footage. Results show that the pipeline achieves high performance in detecting players and on Oficials, with strong precision, recall, and mAP scores across most classes. Ball detection remains the primary challenge due to its small size, rapid movement, and frequent occlusion. Despite this limitation, the findings demonstrate that AI can reliably extract player-level spatial information from a single broadcast camera. This work highlights the potential for afordable, scalable computer vision systems in soccer analytics. By reducing the reliance on specialized hardware, the proposed approach opens the door for colleges, academies, and amateur clubs to adopt data-driven methods traditionally accessible only to professional teams.

Player Performance Lab

Developed an interactive R Shiny application for soccer scouts, fans, and coaches to explore and facilitate player discovery. Integrated an external API to retrieve real-time player statistics, with filtering options for key performance indicators. The app generates custom visualizations of KPI-metrics and salary prediction models to determine if are worth their earnings. Designed to support data-driven recruitment decisions, the tool combines exploratory data analysis with predictive modeling in an accessible, user-friendly interface.

Predicting Credit Card Approvals: A Machine Learning Study

Learn more

Classification Models for Risk Assessment and Fair Decision-Making

I built a machine learning pipeline to predict credit card approval decisions using applicant data, exploring models like logistic regression, decision trees, random forests, and gradient boosting to understand the tradeoffs between accuracy and interpretability. Along the way, I addressed class imbalance and evaluated performance using cross-validation and standard classification metrics. I also looked beyond model performance by analyzing fairness across sensitive attributes and reflecting on the ethical implications of using automated systems in financial decision-making, ultimately presenting the results with practical takeaways.

Evaluating Education Access for Conflict-Affected Girls in Mali

contributed to the evaluation of PASCOFI, a program focused on improving educational access and outcomes for girls affected by conflict in Mali. My work involved supporting data collection and analysis to understand the program’s impact on enrollment, attendance, and retention. I helped design surveys, cleaned and validated student- and school-level data, and produced summary statistics and visualizations to communicate key findings. Working with multilingual teams, I also helped ensure that context-specific education indicators were interpreted accurately, contributing to recommendations for scaling the program in conflict-affected regions.

Assessing Middle School Math Outcomes through Mixed-Methods Evaluation

I contributed to a U.S. Department of Education–funded evaluation of Citizens Math lessons in middle school classrooms, conducted by the American Institutes for Research in partnership with WestEd. The project examined the program’s impact on students’ math skills and their perceptions of the subject. In my role, I tracked participating schools, automated the extraction and processing of district administrative records, and cleaned and analyzed student and teacher survey data. I also coordinated with district and school partners to manage communications and conducted preliminary quality checks to ensure data accuracy throughout the study.

Randomized Controlled Trial Evaluation in Côte d’Ivoire, Democratic Republic of Congo, and Senegal

As part of an IDRC-funded partnership between the American Institutes for Research and Dalberg, I contributed to a large-scale randomized controlled trial evaluating the impact of FLIP programming on multilingual foundational learning. My work included designing quantitative research instruments, collecting data through teacher surveys, student assessments, and classroom observations, and analyzing teacher and student outcomes using OLS regression with covariates for precision. I supported sample selection, power calculations, and the adaptation of validated tools to measure educational outcomes in multilingual contexts.

Analyzing Patterns in Emergency Care Access and Utilization

This project analyzed 2021 U.S. hospital emergency department (ED) visit data to understand patterns in after-hours utilization. The findings showed that nearly half of ED visits occur between 5 p.m. and 8 a.m., when other care options are limited. The analysis highlighted higher after-hours usage among pediatric patients, rural populations, and those experiencing trauma, overdose, or poisoning. Insights from this study supported policy discussions on the importance of maintaining 24/7 hospital access, especially as other healthcare sites close during off-hours.
