DATA SCIENTIST AND DESIGNER

ABOUT ME

I am a data science and design student interested in exploring the intersection of computational sciences, design and fashion. Originally from Cape Town, South Africa, I am currently enrolled in Minerva Schools, a “mobile” university whose rotating campuses will take me to 7 different cities around the world over the course of my undergraduate program.  Between June and August 2018 I was based in Cape Town as a design/editorial intern for Design Indaba, an online design publication which hosts an annual international design festival. Currently, during my 2018 fall semester in Berlin, I am complementing my studies by working on marketing and communications at an online fashion magazine and creative agency, LISSOME

DATA SCIENCE

MACHINE LEARNING ACCOMPLISHMENT CLASSIFIER FOR THE MINERVA PROJECT

Link to full paper
The Python classifier model categorises the accomplishments submitted by Minerva applicants into 1 of 50 different categories. Over- and under-sampling methods are used due to the imbalanced nature of the data. The final accuracy of the classifier falls around 0.58 to 0.62.

MATCHING ALGORITHM FOR THE MINERVA PROJECT

Link to full paper
The matching algorithm optimises matches between student mentors and admitted students based on country of origin, secondary status (high school, gap year or transfer student) and interests, while distributing the admitted students so that each mentor has a manageable load.
