I'm an AI enthusiasts who enjoys participating in data science competitions and using machine learning and deep learning techniques to solve interesting problems. I'm also a developer who enjoys building applications to help my community. I'm currently an undergraduate at the National University of Singapore, pursuing a Double Degree in Mathematics and Computer Science. My current research interest is in copyright protection in the field of generative AI.

• [Investigating Copyright Issues of Diffusion Models under Practical Scenarios] An automated pipeline is built to create a dataset that tests for copyright infringement issues within the latest Stable Diffusion models, including Stable Diffusion XL. We published our results to show that even the most cutting-edge Stable Diffusion model suffers from the problem of generating copyrighted content.

• [Simple Maths Expression Solver] A web application that takes in a photo of a simple handwritten mathematical expression and evaluates the numeric answer. The neural network uses CNN layers and has an architecture that is inspired from the VGG-16 architecture.
• [Address Extraction] A neural network is built using the BERT model to extract street names and point of interests from a dataset containing messy Indonesian addresses.
• [Stock Prices Analysis] By engineering features from historical data, a neural network using 1D-CNN and LSTM layers is built to predict the short-term trend of a particular stock's price.

• [Registration Platform] A web application that is built during the Covid-19 pandemic to help a church to keep track of the number of people who will be attending the physical Sunday worship service.
• [Centralised Database] A web application that is built to aid a company to share training resources with the rest of their employees. The web application automatically synchronises the resources uploaded to Google Drive by the admin.
• [Bus Search] A web application that displays the cheapest and shortest route between two bus stops in Singapore.

• [Productivity Bot] A discord bot that keeps track of the number of hours put into working/studying through a clocking in and out system. A leaderboard ranked by hours of work done can be generated by the admin through the bot.
