Past Projects

PennApps 2020

Mira Tellegen, Andrea Tongsak, Alyssa Tan, and Vivian Zhang

I created this app with my team at the PennApps '20 hackathon, and our work placed in the top ten, and won in the Education Route. The product is an iPhone app coded in Swift, which uses an embedded Mabox API to place data points on the map indicating danger of sexual assaults on campuses. The app also features authentication in Firebase.

HackDAVIS 2021

Mira Tellegen, Foad Olfat, and Harpreet Padda

I created this app with my team at the HackDavis '21 hackathon. The product is an Android app coded in java, and is based on the Kickstarter concept, but allows communities to advertise community service opportunities. This app had two full prototypes, one created as a java GUI using SceneBuilder and MongoDB, and a second iteration built in Android Studio.

Technica 2020

Mira Tellegen, Aastha Senjalia, Ash Freels, and Andy Tongsak

I created this app with my team at the Technica '20 hackathon. The product is a webapp coded in HTML/CSS with JavaScript functionality. The halloween-themed app uses public record CCTV, gun offender, and sex offender databases from Baltimore, which we processed and geo-tagged. The app utilizes the Mapbox API to mark danger in neighborhoods, as a safety tool for Trick-or-Treaters. 

Network Science 2020

Mira Tellegen and Caio Carnauba

I conducted this research with my team in my Network Science course. Our goal was to use Network Science techniques for text processing in Julia, to categorize short text fragments that constitute "unclean data". We found that much of the existing work with Network Science semantic text analysis concerned long documents, and existing work with short fragments was often through machine learning. We wanted to use text vectorization and hamming distance formulas to assess the sentiments of Amazon review titles in an existing dataset. We were able to create neighbors for review titles by their hamming distance from other vectorized texts, with bag of k-gram techniques, and eventually plot visibility clusters in Julia and create meaningful sentiment clusters. 

Abstract Algebra 2021

Mira Tellegen, Delaney Gaughan, and Lilith Hafner

I conducted this research with my team in my Abstract Algebra course. We aimed to survey current research and results in the field of Algebraic Statistics, to understand statistical methods through the lens of Algebra. We found that choosing random points in experimental design could be understood through creating polynomial functions through interpolation on the transects of an area, then randomly sampling the resultant algebraic varieties, and we also explored the effect of Gröbner bases, Riemann metrics, and contingency tables.
