Nabeel Seedat
Hi ๐ I am a PhD student in Machine Learning at the University of Cambridge supervised by Prof. Mihaela van der Schaar. My research interests are data modality agnostic, focussing on: Data-Centric AI, Uncertainty Quantification, Synthetic Data & Trustworthy ML.
Since data is the fuel for ML, my research aims to develop systematic data-centric approaches applicable to different data modalities (tabular, image & text) — to make ML systems more reliable & trustworthy ๐ฆพ, whilst also improving model performance & training efficiency ๐. Most recently on Large Language Models (LLM)s!
I hold an Masters degree from Cornell University working on Bayesian Deep Learning, as well as a Masters from the University of the Witwatersrand (South Africa) working on Signal Processing & ML for Parkinson’s Disease. I also hold a dual-bachelors in Information Engineering & Biomedical Engineering from the University of the Witwatersrand (South Africa). Before starting my PhD I have spent time working on production ML systems as a Data Scientist focussed on Computer Vision at Shutterstock (USA) and an ML Engineer focussed on NLP at Multichoice (Africa’s largest multimedia company).
