About Me

I am a Computer Science with Artificial Intelligence graduate from the University of Nottingham, where I achieved a first-class honours. My main areas of interest revolve around Machine Learning and Computer Vision, having completed several projects in these fields. Since working with data is central to my projects, I expanded my focus into data science as well.

I enjoy exploring new ideas. This led me to pursue academic research and apply the knowledge on real-life projects. My personal workstyle is highly detail-oriented. For me, the fine details are what separates high-quality projects from normal ones. Because of this, I would rather submit a project slightly later than turn in unfinished work. That said, I am fully confident in my ability to complete tasks in a reasonable time frame.

Projects

  • Synthetic Data: Combining Realism and Unrealism

    For my individual dissertation, I was supervised by Professor Andrew French. I learnt Unreal Engine 5 from scratch to develop a image synthetic data generation pipeline. I then combined the synthetic data with the Cityscapes dataset to train a segmentation model on my university's remote GPU server, achieving a 6% increase in accuracy over the baseline model trained with only real data.
  • Obstructive Sleep Apnea (OSA) Prediction Webpage

    I led a team to consisting of me, Chen Ing Low and Gabriel Yong to develop a webpage capable of predicting OSA and its severity with an accuracy of 96%, effectively facilitating OSA diagnosis. I built the prediction models for the webpage using raw datasets collected from Malaysian hospitals which I cleaned and preprocessed.
